CP5 HLOS: "Not all doom and gloom"

This is article was originally published in Rail Magazine in 2019.

In 2012 the Department for Transport published its high-level output specification (HLOS) for control period 5 (CP5), covering the period from April 2014 to March 2019. The 5 year, £38bn plan promised to deliver 1,360 route km of electrification by 2019, and to transform rail travel across the length and breadth of the country. 4 months prior to the start of CP5 Rail magazine published a map created by Engineering Focus, which highlighted many of the schemes which were promised to be completed by 2019. Now that CP5 has come to an end and CP6 has begun, it is a good time to see what has been achieved, which schemes were postponed, which were cancelled and which schemes are behind schedule.

As work got underway at the start of 2014 passengers were reassured that any disruption between 2014 and 2019 would pay off, as new services, new trains and quicker journeys would be delivered once the work had been completed. Unfortunately only 1 year into CP5 it was clear that electrification of the GWML between London Paddington, Bristol, Cardiff and Swansea was not going to plan. By the summer of 2015 the original budget of £800m had more than tripled to £2.8bn, therefore in a bid to keep costs under control and to keep electrification of the GWML on track, the government announced that a number of electrification schemes would be "paused".

Initially, it was announced that Midland Main Line (MML) and Transpennine electrification would be paused, whilst electrification of a number of GWML routes would be deferred. The routes deferred included Didcot Parkway to Oxford, Bristol Parkway to Bristol Temple Meads, and lines to Henley and Windsor. The electric spine which promised to provide an electrified route for freight services from Southampton to the Midlands and across to the MML was also paused.

The pause was intended to allow the DfT and Network Rail to assess which schemes should receive priority and it was thought that some schemes would simply be pushed into CP6. However in 2017 the government made the announcement that the line between Cardiff and Swansea would not be electrified at all, and worst still electrification of the Valleys lines would also be cancelled altogether. Electrification of the Midland Main Line north of Kettering and Corby was also cancelled, as was the electrification of the line between the WCML and Windermere.

Funding for the electrification of the East-West route between Oxford and Bedford was withdrawn and electrification between Reading and Oxford was deferred. It is now unclear if any part of the proposed electric spine will be delivered. Conversion of the line between Basingstoke and Southampton from 3rd rail to overhead is also now off the table, so any hopes that freight operators had of an electrified link between Southampton and the North have been dashed.

It is now hoped that electrification between Bristol Parkway and Cardiff will be completed by January 2020, over a year behind schedule. Whilst passengers have benefited from the introduction of new class 800 bi-mode units which began to enter service in late 2017, those travelling from South Wales have yet to feel the full benefits of electrification, such as the promised reduction of the Cardiff to London journey time of 15 minutes. 





The original article was accompanied by a map which showed which projects were completed, delayed or cancelled. Correct as of spring/summer 2019. A full-size PDF can also be viewed here

The North West electrification programme (NWEP) also suffered a number of setbacks. Whilst Transpennine Express did begin to operate electric services between Manchester Airport and Scotland via Chat Moss/WCML from December 2013, electric services between Liverpool Lime St and Manchester Airport did not begin until March 2015, 3 months behind schedule. The 3 month delay although relatively modest, was a sign of further delays to come. As the NWEP progressed the timescale for the opening of subsequent phases began to slip. Poor ground conditions, known and unknown mine workings were blamed for the delays, which in August 2015 led to Balfour Beatty pulling out of the project after completing only 2 out of 7 phases. The route from Manchester to Preston via Bolton was originally scheduled to be complete by December 2016, however delays meant that class 319s did not begin to operate on the line until February 2019.



 319 362 stands at Liverpool Lime St before setting off for one of the first electric services between Liverpool and Manchester in March 2015.

A report by the Nation Audit Office published in November 2016 found that there were major failings by Network Rail which lead to the cost of electrification of the GWML between Maidenhead and Cardiff to rise to £2.8 billion. The NAO stated that Network Rail “was too optimistic about the productivity of new technology”, and that “It [NR] underestimated how many bridges it would need to rebuild or modify”. The report also highlighted the fact that NR failed to manage the challenges of using new electrification equipment, which had not been tried or tested previously anywhere in the world.


The NAO report acknowledged that electrification of the GWML was complex and the fact that the railway passed through heritage areas and areas of outstanding natural beauty, which provided additional challenges. The report also attributed some of the blame to the DfT, which it said: “did not produce a business case bringing together all the elements of what became the Great Western Route Modernisation industry programme until March 2015”. This was more than 2 years after placing the order for new trains and over a year after Network Rail began work to electrify the route.

So far, of the electrification schemes paused or deferred, announcements have only been made regarding Transpennine and MML electrification. Transpennine electrification will now take place during CP6, although NR is yet to release any concrete plans. As for the MML, it will now only be electrified as far north as Market Harborough, in order to provide a connection of the newly electrified sections between Kettering and Corbyn to the National Grid.

It wasn't only electrification schemes that faced cutbacks and delays, with the full Northern Hub programme yet to be realised and uncertainly remains over when or if key elements will be delivered. A crucial element of the Northern Hub project was to unblock the bottleneck between Manchester Piccadilly and Oxford Rd, this was to be achieved with the construction 2 new through platforms at Piccadilly and widening of the viaduct between Oxford Rd and Piccadilly, in addition, Oxford Rd station was to be substantially remodelled. Yet to date no work has taken place and there are questions over whether or not the proposal will ever commence.

The £85m Ordsall Chord which formed part of the Northern Hub project was complete in 2017, allowing trains to travel between Manchester Victoria and Manchester Piccadilly for the first time, and a number of smaller schemes have been completed or are underway across the Pennines, which seek to improve reliability and reduce East-West journey times.

It's impossible to talk about CP5 without mentioning Crossrail, although not strictly part of the CP5 HLOS, it was expected that trains would begin operating from Heathrow and Reading through central London to Shenfield and Abbey Wood by the end of 2018. However, just months before services were expected to begin it was announced that the opening date would be pushed back to autumn 2019. Now it is thought the section through central London will not be fully completed until 2020 or possibly 2021. The budget for the project has risen by £3bn, with the cost rising from £14.8bn to £17.6bn. 


(The central section of Crossrail is now not expected to open until 2020)

It's not all doom and gloom however, the North West electrification programme was largely completed during CP5, with the exception of the line between the WCML and Windermere. Despite the delays, services across the North West have been transformed and now finally new trains are beginning to enter service.

In Scotland the Edinburgh Glasgow Improvement Programme (EGIP) saw the electrification of 150 route kilometres of railway between Cumbernauld and Newbridge Junction which allowed new class 385 EMUs to enter service between the 2 cities. Electric services between Edinburgh Waverley and Glasgow Queen Street via Falkirk High commenced in 2017, initially operated by class 365s and class 380s up until summer 2018, when class 385s built by Hitachi at Newton Aycliffe were finally signed off for passenger use.

Although improved East-West connections across London are delayed for now, North-South connectivity has been transformed, thanks to the £7bn Thameslink programme which had been underway since 2009 and was complete towards the end of CP5, allowing trains to operate from Bedford and Cambridge through the capital to Brighton and Gatwick Airport.

I think to say that CP5 didn't go to plan is somewhat of an understatement, however, whilst the updated version of the map does highlight those schemes which have been delayed or cancelled, it should also serve to highlight some of the great achievements accomplished during the 5 years between 2014 and 2019. And many passengers are starting to see the benefits, now that a large number of new trains are finally beginning to enter service.

Trans-Pennine electrification and Crossrail North


I feel that I should begin this post with a disclaimer as I know investment in the North is a contentious issue, however I do believe there needs to be some balance brought to the debate. So to begin, I am based in the North and I wholeheartedly agree that at the very least the Trans-Pennine rail route between Manchester, Leeds, York and Selby should be electrified, in addition the government should be investigating options for a new Trans-Pennine rail route.

However, with no decision yet made regarding electrification other than to say it has not been cancelled (to date Aug 2017), I feel I should point out that electrification is just one part of the project to upgrade east-west rail links otherwise known (currently) as the Great Northern Rail Project.

The only 2 statements from the government which provides any indication of their position on electrification are the following:

"Major upgrades to the Manchester – Leeds – York route are currently being designed and developed, to enable us to deliver better journeys for passengers from 2022", DfT spokesperson told Railway Gazette 24th of July 2017.

and

If there are bits of the TransPennine network that are complicated to do and we have a bi-mode train, we can say: ‘Here is a section we can have a diesel.’ We will be electrifying TransPennine but we can do it in a smarter way" Chris Grayling Financial Times 21st of July 2017.

I have already covered the cancellation of Swansea - Cardiff and MML electrification in detail, which helps to explain some of the reasons why it is not possible to simply throw money at a project. Instead this post will focus on the Trans-Pennine route, the challenges ahead and what is being done to improve services. I will also examine the differences between Trans-Pennine links and potential investment in Crossrail 2


New Trains

First of all, there are big changes on the way for both Northern and TransPennine Express which will vastly improve services for passengers without the need for further electrification.

Northern will begin to introduce brand new diesel and electric trains from Dec 2019 and in the meantime will introduce 8 "Flex" bi-mode trains converted from electric class 319s to diesel-electric class 769s. The new Flex trains will be able to operate solely on electric power on the parts of the network already electrified, but will also be able to operate off of the electrified network to places such as Windermere.

Northern already has 20 electric class 319s in service, operating between, Liverpool, Manchester and Preston and from May 2018 will be in operation between Preston and Blackpool. 

TransPennine Express have already begun to fully refurbish their fleet of 51 class 185 trains which will feature plug and USB sockets at each pair of seats, bigger tables, refitted toilets, wifi and LED lighting.

From 2018 brand new five car trains will be introduced to operate between Liverpool, Manchester, Huddersfield, Leeds, York, Scarborough and Newcastle. From 2019 the new trains will also begin operating to Middlesbrough. 

New trains will also allow the introduction of direct links between Liverpool and Glasgow from 2018. In addition from 2019 the Liverpool to Newcastle service will be extended to Edinburgh.

Between 2018 and 2020 a total of 44 brand new trains will be introduced on the TransPennine Express network which will provide 20,000 addition peak time seats per day.


Infrastructure upgrades

To facilitate new services and increased capacity Network Rail have already been busy upgrading the Network between Liverpool - Manchester and Leeds. The projects listed below are just some of the key improvements that are underway, planned or already complete.

The projects listed below are ones that are underway, completed or planned and will provide tangible benefits for passengers. I have tried to focus on upgrades that will improve capacity and or journey times rather than just like for like renewals.
  • Liverpool Lime Street Improvement Programme is part of a £340m package of upgrades and renewals across the Liverpool City Region. This complex phase will be vital in order improve capacity and service reliability. Once complete the upgrade will allow for 3 new services an hour to operate from the station.
  • Huyton Roby 4th track will be complete later this year and will allow intercity services to overtake local stopping services along the route which will improve journey times between Liverpool and key northern towns.
  • Weaver to Wavertree re-signalling works will take place over the summer and will result in improved reliability.
  • Halton Curve which will be complete by Dec 2018 will allow new services to operate initially between Chester and Liverpool Lime St via Helsby, Frodsham, Runcorn, Liverpool South Parkway. In the future it is hoped that services will be extended to serve North Wales.
  • Ordsall Chord will connect Manchester Victoria and Piccadilly stations for the first time. The new chord will allow direct trains to operate between Manchester Airport and the North of England and will reduce congestion at Manchester Piccadilly.
  • Calder Valley upgrade phase 1 which was completed in 2016 saw the renewal of track and signalling between Manchester Victoria and Littleborough which will lead to improved journey times and reliability. In December 2016 a new bay platform at Bradford was also delivered, the new platform removed a conflict between trains to and from Manchester and other onward services.
  • Phase 2 will see further renewals of track and signalling between Littleborough and Bradford Interchange. The upgrade once complete will "paving the way for faster journeys between Manchester Victoria and Bradford interchange" Network Rail
  • North West electrification which has already transformed journeys between Liverpool - Manchester and Scotland will be fully completed in early 2018 when the final section between Preston and Blackpool is finished. The £300m project has increase capacity and reliability between Liverpool and Manchester and between Manchester and Scotland. 
Smaller renewal projects, upgrades and vegetation management schemes are underway across the Network with some work already underway or planned to support future electrification of the Pennine route,  

The problem with new rolling stock and rail upgrades is that they take time to be delivered. New franchises for Northern and Transpennine Express were let in April 2016, yet passengers will not begin to benefit from New trains until 2018. Until the new trains arrive passengers will not fully benefit from work being undertaken by Network Rail, so it is easy for passengers to feel as though nothing is being done to improve services, which is far from the truth.


Crossrail North ("HS3", "Northern Powerhouse Rail")

People in the North have always felt as if we get a rough deal when it comes to transport investment, a feeling which has been recently exacerbated with growing uncertain about Trans-Pennine electrification and the Transport Sectary's apparent support for Crossrail 2, although the project has yet to gain funding.

Having followed a number of projects in the North recently I can't say I fully support the view that we are hard done to, however I know that if the North is to grow and thrive east-west rail links must be improved and believe that proposals for a new line should be explored in detail.

In order to examine the potential causes for the discrepancy between spending in the North and in London I have explored 3 potential proposals for Crossrail North (CRN) and compared them with the proposals for Crossrail 2. In order to do this I have estimated distances for CRN and CR2 so that they may be compared.

As we do not yet know what a "Crossrail North" would look like I have calculated some approximate distances for 3 potential routes.

  • Liverpool to the ECML at the junction with the Leeds and Selby railway via Manchester, Halifax, Bradford and Leeds. Potential distance 135km with 25-30km of mountainous or hilly terrain.
  • Liverpool to the ECML at the junction with the Leeds and Selby railway via Manchester, Huddersfield and Leeds. Potential distance 125km with 20-25km of mountainous or hilly terrain.
  • Manchester West to a junction with HS2 North of Garforth via Leeds, bypassing Halifax, Huddersfield and Bradford. Potential distance 72km with 25-30km of mountainous or hilly terrain.
A true east-west railway should span from Liverpool to Hull, a distance of approximately 190km, this could include new sections of track, upgrades to the existing infrastructure and further electrification. E-W journey times could potentially be improved with infrastructure improvements between Manchester and Leeds, but would people living in Liverpool and Hull argue that they are missing out on investment in favour of Manchester and Leeds?

Would CRN have to be a high-speed line (say 200 to 225 km/h)? With a potential line distance of 60km or more between Manchester and Leeds, trains would have to travel at an average speed of 120km/h non-stop to achieve the 30 minute journey time which IPPR are campaigning for.

120km/h (75mph) is easily achievable however that is simply the average speed and does not factor in acceleration or additional stops at or close to Halifax, Huddersfield or Bradford. The terrain between Manchester and Leeds is also challenging which could require sections of track with a maxim speed lower than 120km/h.

IPPR North currently has a petition running calling for "More money for transport in the North", whilst I do not fully support the Crossrail 2 vs Crossrail North argument I would urge people to show support for improved transport in the North.


Crossrail 2

The route from Broxbourne to Epsom and Shepperton would be approximately 60km in length with approximately 30km of tunnelling underneath central London between Tottenham Hale and Wimbledon with a spur between Severn Sister and Alexandra Palace. The tunneled sections would constitute the only genuinely new sections of railway that would be constructed. As with the Elizabeth Line (Crossrail) the above ground sections of the line would use existing lines, with upgrades, renewals and improved stations. 

The estimated cost for CR2 is said to be £30bn of which 50% would be paid for by London itself through fares and by other means.

CR2 if built to the same standard as the Elizabeth Line would have a maximum speed of 140km/h and be designed to handle 24 trains per hour.

Comparison

It is difficult to compare CR2 and CRN as they are completely different types of railway, CRN would be a regional railway linking distant population centres spanning 180km, whereas CR2 connects suburban lines through a densely populated region to central London spanning just 50km

Looking at population and GVA (Gross Value Added) of the North vs London also demonstrates difficulty in comparing CR2 to CRN.

The combined GVA of the North West, North East and Yorkshire and Humber regions combined in 2015 was £316bn, whereas the GVA for London alone was £378bn, generating 22% of the UK's entire wealth.

At first glance, the £316bn generated by the North seems comparable to the £378bn generated by London, but when you compare the "North" as described above which spans an area of 37,000 km² compared with London just 1,500 km² you see that providing transport connectivity over such a large area is not straight forward. Building a "Crossrail North" on its own would not unlock the potential of the North as a whole.

If we look at population spread also, we find that combined population of the 6 city regions spanning 180km east to west which could potentially benefit from improved east-west links has a combined population of 8.4m, whilst the population of Greater London spanning just 50km north to south is 8.5m.


Conclusion?

Can a satisfactory conclusion be drawn from all this? It's difficult to say, but I do know that whilst investment is vital, simply securing funding is only the beginning. As we have witnessed with electrification, providing fully costed proposals, robust plans and the skilled workforce required are the first hurdles to overcome before work can begin. Construction of course brings its own set of challenges and if not planned correctly can fall foul of unforeseen complications which can add to the cost and delay completion.

Would the £59 billion ‘catch-up cash’ demanded by IPPR North solve all of the North's transport problems? That all depends on how it is spent and over what period, it is all well and good having funding available, but are there £59bn worth of costed 'shovel ready' transport proposals in the pipeline and is there a large enough skilled workforce available to undertake the work? 

Perhaps as the Glasgow-Edinburgh and GWML electrification programmes come to an end the government can reassess its position on electrification and which lines to prioritise next. I doubt Network rail will want its new multi million point electrification trains sitting idle once the GWML is complete.

The only thing that I feel certain of is that improving transport links in the North will not be simple and any comparison between spending on improvements in the North vs investment in Crossrail 2 are unproductive.

Electrification - what went wrong?

I don't normally like to write negative or political headlines, however reading the news about the announcement that electrification schemes are to be scrapped on Thursday (20th July) caused me to reflect on promises made by Government back in 2012

The CP5 HLOS (Control Period 5, High Level Output Specification) published in 2012 was full of promises and seemed a real boon for the rail industry. Electrification of the GWML between London to Cardiff, Oxford and Newbury was finally given the go ahead after being delayed in 2010.

Midland Mainline, North West, Transpennine and other electrification schemes were also announced, all due to begin in or be completed during CP5 which covered the period from 2015 to 2019. A map produced by the Department for Transport which set out ambitious plans can still be found here.

Now it seems that a number of these electrification projects will not go ahead, on Thursday (20th July) the Department for Transport announced that electrification of the GWML between Cardiff and Swansea will no longer go ahead, nor will the electrification of the Midland Main Line. Planned electrification of the section of railway in the Lake District between Oxenholme and Windermere has also been cancelled. 

GWML electrification


Cost overruns and delays to the GWML electrification programme could be one reason why the government has lost its appetite for further electrification. The upgrade of the GWML was first costed at around £600m to £800m, however the budget now stands at £2.8bn. 


Great Western Railway will begin to phase out HSTs later in 2017 as they begin to deploy new bi-mode IEP sets. 


Problems such as Network Rail's approach to planning in which permissions were sought for changes to each individual structure rather than for large sections [1], the much lauded high output electrification train did not initially deliver the intended level of output and difficulty designing and installing OHLE on listed structures all contributed to cost overruns and delays.

In hindsight it seems that government plans to electrify so much of the network in a relatively short period of time were overly ambitious. After years of under investment and not having electrified a main line since the ECML was completed in 1991 the UK rail industry simply did not have the skilled workforce, expertise required nor the right equipment to undertake such a large programme of electrification.

There were problems too with the North West electrification programme, although 2 key sections between Liverpool and Manchester were completed in 2015, phases 3 to 7 were delayed after Network Rail and main Contractor Balfour Beatty agreed that the company would not continue with the project.

What went right?

It's not all doom and gloom, it would be unfair to say that Network Rail has failed or that improvements have not been delivered. Key projects across the network have been completed in the 5 years since the CP5 HLOS was announced.

Electric trains began operating between Liverpool and Manchester in March 2015 providing improved journeys for passengers and more capacity. In 2013 new electric trains were operating between Manchester and Scotland which was one of the most crowded routes outside of London. It is also anticipated that the final phases of the North West electrification programme will be completed in early 2018, with the exception of Oxenholme and Windermere.

The very first public passenger service using electric trains between Liverpool and Manchester

A £750m project to improve Birmingham New St Station was also completed in 2015, with a new 3,300 square metre atrium which is now filled with light thanks to an impressive plastic and steel roof. 

The ETFE roof that now covers the "Grand Central" atrium at Birmingham New St
 

The Edinburgh Glasgow Improvement Programme (EGIP) which aims to upgrade key junctions and infrastructure as well as electrification has been underway since 2013, with electrification between Glasgow and Edinburgh expected to be complete by Autumn 2017.

Crossrail may steal the show in London (in terms of rail infrastructure) but the ThamesLink Programme which hasn't been without its controversy has been steadily transforming a crucial part of London's rail network since 2009. 12 car trains began operating between Bedford and Brighton in 2011 and brand new class 700 trains began arriving in 2016.

New look platforms at London Birdge which had already been completed by 2015
 

The last element to be completed which is also one of the largest and most complex elements of the project has been the transformation of London Bridge, work began back in 2013 and due to be completed by 2018.

There are numerous other projects planned, underway or complete which are listed on Network Rail's website

The future is bi-mode?

Part of "what went wrong" isn't anything to do with budget or planning, but rather Government oversight. In the past 5 years rolling stock technology has advanced significantly. The bi-mode class 800 IEP trains once thought to be a stopgap have turned out better than many expected, even with diesel engines fitted, passengers will enjoy benefits of modern trains, quicker journeys and extra capacity.

Hull Trains, Transpennine Express and Abellio East Anglia have all ordered various bi-mode diesel-electric trains, which will be able to take advantage of the parts of the network that are electrified, whilst also being able to operate on non-electrified lines.

Alternative forms Motive power have also advanced significantly, Alstom has already begun testing a hydrogen fuel cell powered train in Germany and a battery powered train has already been tested on the UK rail network.

The fuel cell powered Coradia iLint built by Alstom has already been tested up to a speed of 80km/h, with hopes to operate the first test passenger services in 2018.

In 2015 Network Rail trialled a battery-powered passenger train between Harwich International and Manningtree, a Class 379 Electrostar was fitted with lithium iron magnesium phosphate batteries which provided enough power to propel the train for about 96km

In the West Midlands battery technology will be retrofitted to 21 of Midland Metro Urbos 3 trams in order to remove the need for the installation of OHLE "in architecturally sensitive areas". The extension of the Midland Metro from New Street station to Centenary Square, which is due to open in 2019 will run through Victoria Square without the installation of overhead line equipment.

Birmingham New St, currently the last stop until the new extension is completed in 2019
 


So, what can we conclude from all this? Despite my initial feeling of pessimism on Thursday morning, after reflecting on the news and reading Nigel Harris' comment about bi-mode technology in Rail issue 831, I feel that whilst it is not a good news story, it is not particularly bad news for the industry or passengers either.

The story will make news headlines for a few days, there will be plenty of analysis for weeks if not months and it will also fuel more anti HS2 feeling. But I think that when all is said and done commuters will go on as normal, not paying much attention to the improvements going on around them, just glad to get a seat, decent wifi, charging point and for the train to be on time.

Isn't it really only people (myself included) who are interested in the railway who care what actually powers the trains? 

My only one concern and it's a big one, is the environment. Diesel fuelled bi-modes will undoubtedly have their place on the network for decades, but I hope and I would urge the government to seek to quickly move to other (greener) forms of power such as battery and or fuel cell technology sooner rather than later. 

I also believe electrification should continue as and when budget and resources allow, but it is unrealistic to think that the remaining 60% UK's network that is not yet electrified can be done so quickly.

Infrarail 2016

On Tuesday I was at the opening day of Infrarail 2016 to see what's new in the world of rail infrastructure.

For those who haven't heard of Infrarail before, it is an exhibition which is held every 2 years which brings together leading railway infrastructure companies from across the world. Attracting upwards of 5000 industry professionals it is the "UK's definitive rail infrastructure event".

One of the first exhibits that caught my eye was that of Aerialtronics who are exhibiting a range of remotely piloted aircraft (or drones). As an engineering photographer and blogger this was bound to catch my attention.

These aircraft are becoming more commonplace and an important tool for inspecting sites. Most people would have seen by now some of the stunning footage Network Rail have published using drones.


Another exhibit of interest was that of the joint venture between Tarmac and Max Bogl. They were exhibiting a slab track system that is aimed squarely at HS2. They envisage that the entire line from London to Birmingham and beyond could be constructed using their slab track system.

I'll be covering this system in more detail in a future blog.


I also had time to catch the latest Crossrail update presented by Director of Operations Howard Smith. With tunnelling complete the emphasis of the project has moved to station fit out, installation of track and systems.

The fit out of the underground stations is now well underway and work has started to improve or build new stations on the western section of the line above ground.

The specialist concreting train that was last used to build the track bed for HS1 is now advancing though the new cross city tunnels. Sections of track under Barbican and Soho are using floating track due to the sensitive nature of the buildings above.

Work on the floating track system has been advancing for some time given the complex nature of the task.

Cossrail is another subject I will be covering in more detail soon.


One of the largest stands at this years event belonged Chinese train manufacturer CRRC Corporation. Rolling stock manufacturers usually exhibit at Railtex which is held on alternate years to Infrarail, however CRRC are clearly keen to enter into the UK market and are pitching high speed trains aimed at HS2 and a conventional EMU model which could also be sold in the UK.

To date CRRC hasn't managed to win any UK rolling stock contracts, however with ongoing electrification and HS2 going ahead there are certainly plenty contracts for them to bid for in the pipeline.

Crossrail

Crossrail is currently the largest construction project in Europe, employing over 10,000 engineers working across 40 work sites. Construction began back in 2009 and is expected to be fully complete by 2019.

The £15bn project will provide London with a new 100km East-West route linking Reading and Heathrow to the West, with Shenfield and Abbey Wood to the East. The route is being made possible with the construction of 42km of new tunnels through the centre of the city.

8, 1000 tonne tunnel boring machines (TBMs) have been busy tunnelling 24 hours a day underneath the streets of London since 2012 and now tunnelling is over 90% complete.

There will be 40 stations on the Crossrail route including 10 new stations at Paddington, Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, Whitechapel, Canary Wharf, Custom House, Woolwich and Abbey Wood.

The new route will increase capacity by 10%, provide more connections with underground lines than any other route and reduce journey times between key locations. Crossrail will provide a direct route between Heathrow and Central London, reducing journey times by up to 10 minutes. The journey time from Heathrow to Canary Wharf for example will be reduced from 48 minutes requiring 2 changes, to 40 minutes with no changes.

The new transformational route will be provided with new modern and spacious trains capable of transporting up to 1500 passengers. The 200m long trains to be built by Bombardier will be able to operate at up to 140km/h, they will contain on-train passenger information systems to deliver real-time travel information and be air conditioned.

The trains will be based on Bombarier's Aventra family of electric trains which will be constructed using lightweight materials making them energy efficient. For Crossrail the 345 classification of Electric Multiple Units (EMUs) will be formed of 9 cars each.

In total 65 of the trains will be built at Bombardier's plant in Derby, this will allow up to 24 trains per hour to operate through the central section of the route between Paddington and Whitechapel.

Fact and Figures,
  • Cost £14.8bn
  • Length 118km
  • Tunnel lenght 42km
  • 4.5 million tonnes of material excavated
  • 10% increase in capacity (the largest increase since World War 2)

One of the most visible aspects of the project so far is the construction of a new station at Canary Wharf. Due to the limited space the new station had to be constructed inside the North Dock of West India Quay. 

The 256 metre long station sits 28 meters below the water level, the station consists of 4 above ground floors and 3 below, providing 100,000 square feet of retail space, as well as a public garden housed under a large arched roof.

The public gardens and retail space are expected to open in May this year (2015), a full 3 years before any trains are planned to stop at the station.
