The Anonymous Widower

Green Light For Revived West Midlands Passenger Service

The title of this post, is the same as that of this article on Rail News.

This is the introductory paragraph.

Passenger trains are set to return to the line between Walsall and Wolverhampton, having been withdrawn 12 years ago. Since then, the line has been used for freight.

These points are made about the proposed service.

The West Midlands Mayor; Andy Street is quoted as saying he’s pleased with the scheme.

And well might he be!

This to me is a classic reopening scheme.

  • There is a fully-electrified freight route, that runs between Walsall and Wolverhampton.
  • There used to be three intermediate stations; Darlaston James Bridge, Willenhall Bilston Lane and Portobello.
  • The first two intermediate stations closed in 1965 and the last in 1973.
  • Network Rail have said, it will be possible to run the extra trains needed.
  • The direct Walsall and Wolverhampton service will complete an hourly or better triangular service between Birmingham, Walsall and Wolverhampton.
  • This triangular route is also fully-electrified.
  • If extra rolling stock is needed, there are quite a few suitable electric multiple units, that are sitting in sidings or will be replaced by new trains in the next couple of years.

Except for the building of the new intermediate stations, nothing would appear to be high cost.

The project must have a high benefit cost ratio.

A Possible Extension From From Walsall To Aldridge

In the Wikipedia entry for Walsall station, this is said.

There are also plans to reopen a terminus single platform at Aldridge for trains to Birmingham New Street via Walsall but not to Sutton Coldfield and Water Orton.

This service would be on part of the freight-only Sutton Park Line between Walsall and Water Orton stations and is regularly used by freight trains avoiding Birmingham New Street station.

This Google Map shows the Sutton Park Line through Aldridge.

Note.

  1. The Sutton Park Line is double track and not electrified.
  2. The road running South of the railway is called Station Road.

There would appear to be space for a reopened station. between the railway and Station Road.

  • It could have a single platform.
  • There could be adequate car parking.
  • There would be no need for an expensive bridge.
  • The station could be designed to be converted into a two-platform station if a full service were to be run on the Sutton Park Line at a future date.

As the station would be no more than about five miles from Walsall station and its electrification, the extended service from Walsall could be run by a battery-electric train.

Conclusion

I predict, that if this route is reopened and it is a success, other parts of the UK will want to open more freight lines to passenger traffic.

These similar projects have already been widely mentioned.

Most of these reopening, would just need refurbishment and some new stations.

Camp Hill Line Set To Gain Third Station

The title of this post, is the same as that of a sub-section on this page on Rail News.

This is said.

PLANS to build a station at Moseley on the Camp Hill line in Birmingham have been submitted. If approved, Moseley will be the third station on the restored route, where Birmingham City Council has already given the go-ahead to stations at Kings Heath and Hazelwell. The line was closed to passengers as a ‘wartime economy’ in January 1941, but the withdrawal was confirmed in November 1946.

 

Under Future Plans on the Wikipedia entry for the Camp Hill Line, this is said.

In July 2018, the Midlands Rail Hub was unveiled which would see reopening of Moseley, Kings Heath and Hazelwell with the chords built to connect Birmingham Moor Street with the line to Kings Norton and another to Water Orton.

In September 2018, the designs of the new stations were revealed as Kings Heath, Hazelwell and Moseley were planned for reopening by 2021 with a frequency of 2 trains per hour.

It looks to me, that Birmingham City Council are going to make the Camp Hill Line an important route across the city.

First Passenger Train In 80 Years Runs On Camp Hill Line

The title of this post is the same as that of this article on Rail Technology Magazine.

These two paragraphs described the route, that the train took on the Camp Hill Line.

On Monday morning a train carrying the Mayor, West Midlands Railway’s customer experience director Jonny Wiseman and other representatives from across the rail industry, travelled along the line.

The train followed the route of what would be the re-opened line, stopping at the Moseley, Kings Heath and Hazelwell sites before arriving into Kings Norton, and later returning to Birmingham New Street.

The article has a picture showing the VIPs showing boards indicating the stations at Moseley, Kings Heath and Hazelwell, that will be reopened.

Wikipedia says this under Future for all three stations.

In 2019, the project to re-open the stations at Moseley, Kings Heath and Hazelwell received £15 million in Government funding, with construction due to start in 2020 and aimed for completion in time for the 2022 Commonwealth Games.

£15million seems good value to reopen three stations.

Let’s hope the world has solved the COVID-19 crisis before the 2022 Commonwealth Games.

Trains For The Service

The picture in the article, shows the test service was run by a two-car Class 170 train. This is an ideal train to do the testing, but as the Camp Hill Line is not electrified, self-powered trains will be needed for the passenger service.

West Midlands Trains will have a good selection of self-powered trains with which to run the service.

  • They already have a selection of Class 170 and Class 172 Turbostar diesel multiple units in very good condition, which total thirty-seven two-cars and twenty-one three-cars.
  • I’m sure Vivarail will pitch diesel-electric or battery-electric versions of their Class 230 trains.
  • Alstom will probably pitch the Breeze hydrogen-powered train.
  • Porterbrook will probably pitch their proposed Battery/FLEX conversion of Class 350 trains.

I don’t think there will be a problem finding a suitable fleet for this route.

I suspect some form of battery-electric train will be used, as there is lots of 25 KVAC overhead electrification in the Birmingham area, that can be used to charge the batteries.

Battery-electric trains with a range of perhaps forty miles would also open up the possibilities for other electric services for West Midlands Trains.

A Thought On Construction

Because of COVID-19, there will probably be numbers of unemployed in this part of Birmingham, who have skills that could be useful to do the building work.

So should the non-railway related parts of the reopening be accelerated to put money in the pockets of the local unemployed.

Boris Johnson Vows New Life For High Streets And Axed Rail Lines

The title of this post is the same as that of this article in The Times.

This is the introductory paragraph.

Boris Johnson is promising to revitalise “left behind” high streets through tax cuts for pubs and shops and reversing some of the Beeching rail cuts to branch lines.

The article gives a map of the lines and here is a list of them.

  • Newcastle and Ashington/Blyth.
  • Bristol and Portishead
  • Camp Hill Line
  • Willenhall and Darlaston
  • Thornton-Cleveleys and Fleetwood
  • Okehampton and Exeter
  • March and Wisbech
  • Uckfield and Lewes
  • A new station he building of a station at Skelmersdale.

I will suggest other possibilities and add them here.

There could be several!

The Technology Is With Us!

Anyone who follows railway technology, as I do, knows that technology coming on stream will ease the creation of these routes.

  • Modern digital in-cab signalling, as already used on Thameslink.
  • Battery-electric trains.
  • Innovative charging for battery-electric trains.
  • Hydrogen-powered trains.
  • Tram-trains
  • Automatic train control
  • Remote services in simple depots.
  • Better bridge-raising and other construction techniques.

Many of these new routes will be able to use a standard train.

Axed Rail Routes May Be Reopened Under New Department for Transport Plans

The title of this post is the same as that on this article on Sky News.

This is the first two paragraphs.

The Department for Transport has confirmed it is actively working with a number of groups to explore the possibility of reopening old rail routes, axed under the so-called Beeching cuts of the 1960s.

It follows a call by Transport Secretary Chris Grayling a year ago, encouraging those in the public and private sector to submit proposals for potential projects to regenerate old lines.

It also quotes a Department of Transport spokesman.

This is on top of exploring reopening the Northumberland Line for passenger use, supporting the reinstatement of stations on the Camp Hill Line, developing new rail links to Heathrow and a new station at Cambridge South

He apparently, didn’t say more because of confidentiality.

The article then talks about the success of the Borders Railway in Scotland.

So is this just a good news story for Christmas or is there a plan to reopen old railway lines?

I feel that a several factors are coming together, that make the reopening of railway lines and the creation of new ones more likely.

Digital Signalling

Signalling is expensive, but where you have rolling stock to a high modern standard, with digital in-cab signalling, does this mean that new or reopened rail lines can be built without conventional signalling?

In addition, installing digital signalling on some routes, would probably make it easier to add a new station. Surely, it must just be a reprogramming of the route!

It could be a problem that, I would expect that on a digitally-signalled line, all trains must be capable of using it. But in many areas of the country, like East Anglia, these routes will be run by new trains.

Digital signalling must also make it easier to design more efficient single-track railways, with perhaps a passing loop to allow higher frequencies.

More Efficient Track Construction

Network Rail and their contractors and suppliers are getting better and more efficient at building track and bridges through difficult terrain and places, judging by some of their construction in recent years, such as the Acton Dive-Under and the Ordsall Chord. They have also overseen some notable successes in the refurbishment of viaducts and tunnels.

It should also be noted that the reopening of the Borders Railway was a successful project in terms of the engineering and was completed on budget and on time.

According to Wikipedia, though there was criticism of the infrastructure.

This is said.

The line’s construction has been described as resembling a “basic railway” built to a tight budget and incorporating a number of cost-saving features, such as using elderly two-carriage diesel trains and running the line as single track.

But looking back on the line from over three years since it opened, it has certainly been judged by many to be an undoubted success.

Would it have had the same level of success, if it had been built as a double-track electrified railway?

Single-Track Lines

The Borders Railway is a good example of an efficient single-track railway, that runs a half-hourly service.

Other routes like the East Suffolk Line and the Felixstowe Branch Line, show how good design can handle more than the most basic levels of traffic, with perhaps selective double track or a well-placed passing loop.

They may be dismissed by rail purists as basic railways, but when well-designed, they are able to provide the service that is needed along the route, for a construction cost that is affordable.

I would though advocate, that if a new single-track railway is built, that provision is made where possible to be able to add the second track. But not at too great an expense or to provide a service level that will never be needed.

I believe that good design of a new railway can cut the construction cost by a fair amount.

Single-Platform Stations

Several of the new stations built in recent years have been stations with only a single-platform.

  • Cranbrook – A station in Devon on the West of England Main Line to serve a new housing development.
  • Ebbw Vale Parkway – A parkway station in Ebbw Vale.
  • Galashiels – A station, that handled 356,000 passengers last year. It is a unique station on a narrow site, that shares facilities with a large bus station on the other side of the road. It is a very functional transport interchange.
  • James Cook – A basic but practical station, that serves the hospital in Middlesbrough. – It cost just over £2million in 2014.
  • Newcourt – A £4million station handling over 100,000 passengers per year.
  • Pye Corner – A basic station in Newport handling nearly 100,000 passengers per year.

The stations have several common characteristics.

  • They can all handle at least a four-car train.
  • The single-platform is used for services in both directions.
  • Disabled access is either level or by a gently-sloping ramp.

Only James Cook station has a footbridge over the track.

These single-platform stations must cost less, as for instance a footbridge with lifts costs upwards of a million pounds.

Note that of the nine stations on the Borders Railway only three have two platforms.

Single-Platform Terminal Stations

There are also several terminal stations in the UK with only one platform.

  • Aberdare – Handling over 500,000 passengers per year.
  • Aberystwyth – Handling around 300,000 passengers per year.
  • Alloa – Handling around 400,000 passengers per year.
  • Aylesbury Vale Parkway – Handling over 100,000 passengers per year.
  • Blackpool South – Handling over 100,000 passengers per year.
  • Exmouth – Handling nearly a million passengers per year.
  • Felixstowe – Handling around 200,000 passengers per year.
  • Henley-on-Thames – Handling around 800,000 passengers per year.
  • Marlow – Handling nearly 300,000 passengers per year.
  • Merthyr Tydfil – Handling around 500,000 passengers per year.
  • North Berwick – Handling around 600,000 passengers per year.
  • Redditch– Handling over a million passengers per year.
  • Seaford – Handling over 500,000 passengers per year.
  • Shepperton – Handling around 400,000 passengers per year.
  • Sheringham – Handling around 200,000 passengers per year.
  • Walton-on-the-Naze – Handing around 130,000 passengers per year
  • Windsor & Eton Central – Handling nearly two million passengers per year.

Many of these stations have only a single hourly train. whereas Redditch and Windsor & Eton Central stations have three trains per hour (tph).

As a single terminal platform can probably handle four tph, I suspect that most terminals for branch lines could be built with just a single platform.

No Electrification

Chris Grayling has said that the East West Rail Link will be built without electrification.

I wasn’t surprised.

  • Network Rail has a very poor performance in installing electrification.
  • There have been complaints about the visual intrusion of the overhead gantries.
  • Electrification can cause major disruption to road traffic during installation, as bridges over the railway have to be raised.

In addition, I’ve been following alternative forms of low- or zero-carbon forms of train and feel they could offer a viable alternative

Bi-Mode, Hydrogen And Battery-Electric Trains

When the Borders Railway was reopened, unless the line had been electrified, it had to be run using diesel trains.

But in the intervening three years, rolling stock has developed and now a new or reopened railway doesn’t have to be electrified to be substantially served by electric trains.

  • Bi-Mode trains are able to run on both diesel and electric power and Hitachi’s Class 800 trains are successfully in service. They will be shortly joined by Porterbrook’s innovative Class 769 trains.
  • Hydrogen-powered trains have already entered service in Germany and they are being developed for the UK.
  • Battery-electric trains have already been successfully demonstrated in the UK and will enter service in the next few years.

All of these types of train, will be able to run on a new railway line without electrification.

Bi-mode trains are only low-carbon on non-electrified lines, whereas the other trains are zero-carbon.

The trains on the Borders Railway must be prime candidates for replacement with hydrogen-powered or battery-electric trains.

Adding It All Up

Adding up the factors I have covered in this section leads me to conclude that rail developments over the last few years have made it possible to create a new railway line with the following characteristics.

  • An efficient mainly single-track layout.
  • Single-platform stations.
  • A single-platform terminal station capable of handling well upwards of a million passengers per year.
  • Service levels of up to four trains per hour.
  • Zero-carbon operation without electrification.
  • Low levels of visual and noise intrusion.

The new railway will also be delivered at a lower cost and without major disruption to surrounding road and rail routes.

The Need For More Housing And Other Developments

There is a very large demand for new housing and other developments all over the UK.

Several proposed rail projects are about connecting new developments with the rail network.

In London Overground Extension To Barking Riverside Gets Go Ahead, I listed a few developments in London, where developers and their financial backers, were prepared to put up around £20,000 for each house to fund decent rail-based transport links.

Obviously, developments in London are expensive, but with all the new developments, that have been built close to stations in the last few years, I suspect that infrastructure financiers. like Legal and General and Aviva, know how much being by a rail station is worth.

Conclusion

Both public and private infrastructure financiers will take advantage of the good railway and rolling stock engineering, which will mean the necessary rail links to new developments will be more affordable and zero-carbon.

The Camp Hill Line Behind St. Andrew’s Stadium

I took these two pictures, as I left St. Andrew’s Stadium after the Ipswich game.

Note the railway track of the Camp Hill Line, with a bridge over it.

This Google Map shows the stadium.

Note the railway line behind the stand on the left.

As it is planned to reopen the Camp Hill Line to passenger services, if Birmingham City were higher in the Leagues, this would surely expect a station to be built here.

New Passenger Rail Routes In The West Midlands

Looking for possible privately-funded rail projects, I have come acrossseveral proposed rail route re-openings and improvement schemes in the West Midlands on Wikipedia.

Birmingham-Peterborough Line

The Birmingham-Peterborough Line is a major route between Birmingham and the East.

I am including it, as there are aspirations to add new stations at Castle Bromwich and Fort Parkway.

Between Birmingham and Nuneaton must be a candidate for in-fill electrification, especially as this section has two freight terminals.

Camp Hill Line

The reopening of the Camp Hill Line across Birmingham has been a long term ambition of the City Council for years.

The current status of the proposed development of the Camp Hill Line is given in Wikipedia under Future Plans.

This is the last part of that section.

In 2017, the newly elected Mayor of the West Midlands Andy Street pledged to get work started on restoring services to the line by 2020. And officials were said to be investigating the business case for a fourth station at Balsall Heath (previously called Brighton Road) This would mean Lifford and Camp Hill would be the only stations not to be reopened.

In August 2017, West Midlands Trains announced plans as part of their franchise deal that the line would reopen by December 2019 as part of a £1 billion investment in the West Midlands. This included a new station at Moseley.

In February 2018, Mayor of the West Midlands, Andy Street, said that the viaduct would not be needed, as Hereford to Birmingham New Street trains could be diverted along this line, meaning that extra capacity at Birmingham New Street was not required to open this line.

Note that the original completion date for this scheme was 2025 and it has now been moved forward to December 2019.

The current scheme seems to include the following.

  • Four new stations at Balsall Heath, Moseley, Kings Heath and Hazelwell.
  • A possible connection into Birmingham Moor Street station.
  • Birmingham New Street to Worcester services would use the Camp Hill Line.

It seems that this scheme provides a rail service to a new part of the city and also releases capacity at Birmingham New Street. I think there’s some Brummie cunning at work and that a simpler scheme is being created, that could involve.

  • The new stations.
  • None or very little new electrification, track and signalling.
  • No connection to Moor Street station.
  • Services from Birmingham New Street to Kings Norton, Redditch and Bromsgrove using new Aventra trains running on batteries on the Camp Hill Line, which would call at all stations.
  • An improved Birmingham New Street to the new Worcester Parkway station using new CAF Civity diesel trains, along the Camp Hill Line.
  • Will CrossCountry’s Cardiff-Nottingham service be rerouted via the Camp Hill Line?

The New Street to Worcester services could be rerouted earlier, if it was necessary to squeeze more capacity out of New Street station.

Note that if all services stopped at Bromsgrove, when it gets its electric service on the Cross-City Line in May 2018, passengers for a lot of destinations, would surely change at Bromsgrove, rather than New Street!

Darlaston Loop

The reopening of the Darlaston Loop has been suggested by Andy Street, who is now Mayor of the West Midlands.

I suspect that this reopening fits within a larger overall scheme.

South Staffordshire Line

Network Rail and Midland Metro, both seem to have aspirations to run services on the South Staffordshire Line.

Re-opening Proposals in the Wikipedia entry gives full details of the proposals. Included are.

  • Freight trains on a single track.
  • Midland Metro on a single track with passing places.
  • National Rail services.
  • Tram-trains sharing with freight trains.

This is the last entry.

In September 2017, the new franchise operators, West Midlands Trains, plans to restore disused railway lines including the South Staffordshire Line which would be an extension of the existing Birmingham to Stourbridge Junction service which it plans to extend to Brierley Hill in the future.

On the Wikipedia entry for the Midland Metro, under Wednesbury and Merry Hill – Extension, this is said.

From Line 1 in Wednesbury, the Brierley Hill Extension (WBHE) would follow the disused South Staffordshire Line, through Tipton to the vicinity of the former Dudley Town station (which closed in 1964 and was later the site of a freightliner terminal), then on-street into Dudley town centre. It would leave Dudley alongside the Southern Bypass to access the railway corridor, leaving it at the approach to the Waterfront/Merry Hill area and Brierley Hill and then on to Stourbridge.

Centro has stated that the WBHE would provide 10 trams per hour, alternately serving Wolverhampton and Birmingham. Journey time from Brierley Hill to West Bromwich was stated as 31 minutes.

There are a lot of possibilities.

Various things might help in the design.

  • There is space for two tracks. It has been suggested that one is for trams and one for freight.
  • Midland Metro’s trams can run on battery power, so no electrification is required, if all other trains are diesel-powered.
  • Midland Metro’s trams and West Midlands Trains’s new diesel trains are both built by CAF, so are they compatible enough to share a track?
  • Modern signalling gets better and better.

I think we might see a very innovative plan for the use of this line.

Sutton Park Line

The Sutton Park Line is another line in the est Midlands area, that could be re-opened.

Re-opening in the Wikipedia entry gives full details of the proposals.

In February 2008 it was announced that Birmingham City Council, Network Rail and Centro were launching a feasibility study to assess the possibility of re-opening the line to passenger services. In January 2015 the line was put on hold for reopening to passenger trains. In April 2017, the proposals were being looked at again as part of a spin-off to the HS2 scheme. In December 2017, it has been proposed that the line could reopen as part of the Governments plans to reopen lines closed in the 1960s and later cuts by British Rail.

I would think, that one of the main reasons, this line is being reopened is that is connects several of the other suburban lines in Birmingham. It also allows freight trains to by-pass Birmingham New Street station.

Walsall-Wolverhampton Line

This is said about reopening a passenger service on the Walsall-Woverhampton Line in Wikipedia under Future Plans.

The West Midlands Combined Authority have announced their intention to restore a passenger service to the line by 2027, along with new stations at Willenhall and Darlaston James Bridge.

Note.

  1. At the present time, this route is for freight.
  2. It has had passenger services on and off for fifty years.
  3. It can be used as a diversion route around engineering works.

If a direct service were to be reinstated it would take just twelve minutes, as opposed to an hour via Birmingham New Street station.

It strikes me that this would be a simple route to upgrade.

Walsall and Wolverhampton stations are electrified.

The route is surely short enough to be handled by a battery-powered train.

Signalling is probably up-to-date.

There is also this report in the Wolverhampton Express and Star, which is entitled Spring Satement: £350m Housing Deal For The West Midlands, which says this.

The deal comes after ministers revealed plans to bring the line between the town and city back into use, including new railway stations at Willenhall and James Bridge, Darlaston.

Things seem to be happening on this route.

Possible New Stations

I’ll summarise the possible new and reopened stations.

Could a common design be created, so that the cost of stations is reduced?

Is There A Plan?

The West Midlands Combined Authority and the train operation company for the area; West Midlands Trains, seem at a first look, taken all the freight and disused routes and seeing how they can be linked into a network to the benefit of Birmingham.

But I think it is more than that!

The trains and trams are a varied fleet.

  • CAF Urbos trams. – Can be fitted powered with batteries
  • Bombardier Aventra trains in three- and five-car units. – Might be possible to be powered with batteries
  • CAF Civity diesel-multiple units in two- and four-car units.

Full details have not been given about the Aventras, but it could be that all trams and trains are capable of moving for perhaps a dozen miles under their own power. Obviously, the CAF Civitiies can go a lot further on diesel fuel.

I have some questions.

  • Could all these trains, mean that the lines can be added to the current network without installing too much electrification?
  • Is it only the South Staffordshire Line and the Darlaston Loop, where new track needs to be laid?
  • CAF are a company noted for innovation, who are opening a factory in Wales. Have they got a Spanish Surprise to help the WMCA create a world-class network?
  • Are architects and engineers working on a unique platform design, that all trains can share?
  • Could the Camp Hill Line and the Walsall-Wolverhampton Line have a passenger service, as soon as there are trains to run the service?

I wonder if there is a plan to bring in new routes continuously!

  • Electric trains  on the Chase Line to Rugeley Trent Valley station and to Bromsgrove station will be first in 2018.
  • Walsall and Wolverhampton using the Wallsall-Wolverhampton Line
  • New Street and Worcester using the Camp Hill Line.
  • New Street and Bromsgrove using new stations on the Camp Hill Line.
  • Coleshill Parkway tand Walsall using the Sutton Park Line.
  • Walsall and Stourbridge Junction using the South Staffordshire Line and diesel trains.
  • Wednesbury and Merry Hill using the South Staffordshire Line and trams.

Note.

  1. The early bonus of the new electrification.
  2. Walsall and Bromsgrove will develop into well-connected hubs.
  3. Euston and Walsall will be introduced by West Midlands Trains.
  4. As the network expands, new trains are delivered.
  5. Stations will be added continuously.
  6. All parts of Greater Birmingham will benefit.

Is this the way, Andy Street will market the network to his customers?

A Detailed Look At A Three-Car Aventra

In Bombardier and CAF To Make 413 Carriages For New West Midlands Franchise, I wondered if the three-car Aventras ordered by West Midlands Trains had a battery capability.

The Train Weight

I need a good estimate of the weight of a typical Aventra carriage.

Wikipedia gives the following values.

  • Bombardier Aventra – A nine-car Class 345  train weighs less than 350 tonnes, which gives a figure of 39 tonnes per car.
  • Siemens Desiro City – A twelve-car Class 700 train weighs 410 tonnes, which gives a figure of 34 tonnes per car.
  • Bombardier Electrostar – A five-car Class 378 train weighs 159.5 tonnes, which gives a figure of 32 tonnes per car.

Bombardier seem to play their weight figures close to their chest, so I’ll just use a figure of 35 tonnes per car. But it does appear that Aventras, could be heavier than Electrostars.

The Battery Weight

I tend to think in terms of New Routemaster hybrid bus batteries, which have a capacity of 75 kWh.  Surely hybrid bus batteries are fairly common and if you were needing a battery for a new application, it might be where you will start.

The best estimate I can make is that a 75 kWh battery weighs about 600 Kg. I will use this until I find a better figure.

Could the weight of the battery explain the increase in weight between an Electrostar and an Aventra?

The Gangway Weight

One thing that could add to the weight of the Aventras of West Midlands Trains, is the fact that they will be built with a gangway.

Will they be able to split and join automatically in a couple of minutes?

Aventras Have A Lot Of Traction Motors

From what I’ve seen on the Internet, it appears that Aventras have a lot of powered bogies.

A Three-Car Aventra

I think that a three-car Aventra would have a formation something like.

  • DMSLW – Driver Motor Standard – Wheelchair and Universal Access Toilet
  • PMS – Pantograph Motor Standard
  • DMS – Driver Motor Standard

Note.

  1. I estimate it would have about 230 Standard Class seats in a traditional layout. or perhaps 150 in a Metro layout.
  2. There would be a couple of wheelchair spaces.
  3. Would a toilet be provided on the train? Crossrail puts them in the stations! Does Birmingham?
  4. Each car would be fully motored.
  5. Could each car have its own battery, so they handled their own regenerative braking efficiently?
  6. All the cars would be connected together by an electrical bus fed from the pantograph car.
  7. West Midlands Trains have said the new trains will be 90 mph units.

The capabilities are not unlike the current Class 323 trains.

The Aventras have advantages over the older trains.

  • They are articulated, which gives more space.
  • They are wider inside due to thin, strong car sides and underfloor heating.
  • Design of lobbies has improved.
  • A mixed traditional/metro interior can be used as in Crossrail’s Class 345 trains.

They could also be designed to a slightly longer length if required. But this might have operational and depot issues.

I expect Bombardier will have used every trick and dodge to get this order.

What Size Of Battery Is Needed To Handle Regenerative Braking?

I’ll do the calculation for one car with perhaps a hundred passengers running at 90 mph or 145 kph.

I’ll assume each passenger weighs 80 Kg with all their baggage, which gives a one-car mass of 43 tonnes.

The amount of energy in that one car is a very surprising figure of just 10 kWh.

How Far Could A Three-Car Aventra Go On Battery Power?

In an article in the October 2017 Edition of Modern Railways, which is entitled Celling England By The Pound, Ian Walmsley says this in relation to trains running on the Uckfield Branch.

A modern EMU needs between 3 and 5 kWh per vehicle mile for this sort of service.

The three-car Aventra will be an efficient train, but it will have features like air-conditioning, so I suspect that a figure of 4 kWh per car-mile will be achievable, if the following is done.

  • Air-conditioning is very intelligent and efficient.
  • The train is very well insulated.
  • All electrical equipment on the train like lights, toilets and doors are efficient.
  • Operation ensures batteries are fully charged before entering battery sections.
  • Pantograph operation will be intelligent to snatch a sneaky charge on a short length of electrification.
  • Regenerative braking energy is stored on the train.

3 kWh per car-mile may even be possible.

Suppose the battery in each car had a capacity of 75 kWh. This would give the following ranges with various energy consumption rates.

  • 3 kWh – 25 miles
  • 4 kWh – 19 miles
  • 5 kWh – 15 miles

It certainly is important to get the train as energy efficient as possible.

Increasing the battery capacity will increase the range proportionally.

This would mean that a very efficient train with a double-size battery could go fifty miles without wires.

Where Practically Could These Trains Run?

There are several possibilities.

Camp Hill Line

The Camp Hill Line is an obvious possibility.

A lot is said about the reopening in Future Plans in the Wikipedia entry for the line.

This is the latest part of the section.

In August 2017, West Midlands Trains announced plans as part of their franchise deal that the line would reopen by December 2019 as part of a £1 billion investment in the West Midlands. This included a new station at Moseley.

There has also been speculation in the railway press, that chords will be created to allow trains on the line to run directly into Birmingham Moor Street station.

Moor Street Station

If these trains were to run into Birmingham Moor Street station would the bay platforms at the station be electrified?

This would allow the trains batteries to be charged before returning along the Camp Hill Line.

But it would open up interesting possibilities.

With electrification at stations like Stratford-upon-Avon and Leamington to charge the batteries, could services South of Birmingham be run by three-car Aventras running on batteries?

Both |Stratford-upon-Avon and Leamington Spa are under forty miles by road from Birmingham,

I think it could be theoretcally possible, but West Midlands Trains are acquiring a lot of diesel trains.

Extending Existing Electric Services

From May 2018, the electric services on the Cross City Line will run between Bromsgrove and Lichfield Trent Valley stations.

Could trains running on batteries extend services?

Conclusion

Three-car Aventras are an interesting possibility.

I think we’ll be seeing a lot of them around the UK.

Bombardier and CAF To Make 413 Carriages For New West Midlands Franchise

The title of this post is the same as this article on Global Rail News.

This is said.

Future operator West Midlands Trains has made a £680 million order with Bombardier and CAF for 413 carriages.

Bombardier will manufacture 36 three-car and 45 five-car Aventra trains at its Derby site, while CAF will produce 12 two-car and 14 four-car Civity trains. In total, 107 new trains will be delivered.

The electric three-car Aventras will operate on metro services, the electric five-car units for outer suburban and long distance, while CAF’s DMUs will run on dedicated services to the towns and cities around Birmingham.

These are my thoughts on the various parts of the order.

The Three-Car Aventras

The thirty-six three-car Aventras will probably replace the twenty-six Class 323 trains, which lack wi-fi and other passenger-friendly features.

It should also be noted that the Aventra has a slightly unusual and innovative electrical layout.

This article in Global Rail News from 2011, which is entitled Bombardier’s AVENTRA – A new era in train performance, gives some details of the Aventra’s electrical systems. This is said.

AVENTRA can run on both 25kV AC and 750V DC power – the high-efficiency transformers being another area where a heavier component was chosen because, in the long term, it’s cheaper to run. Pairs of cars will run off a common power bus with a converter on one car powering both. The other car can be fitted with power storage devices such as super-capacitors or Lithium-ion batteries if required.

This was published six years ago, so I suspect Bombardier have refined the concept, which is probably more to do with spreading weight around the train for better dynamics than anything else!

Obviously for West Midlands Trains, there is no need for 750 VDC, but will there still be a pair of power cars?

So it looks like there may be a reorganisation of the electrical system in the trains.

A few other points.

  • I am surprised that some of the trains aren’t six-cars, as every other set of new trains seem to be single and double lengths.
  • According to Wikipedia, the trains will have end gangways.
  • The trains are air-conditioned and have free wi-fi and power sockets.

Hopefully, the full specification and Tops-number will be disclosed soon.

Are Batteries An Inherent Part Of The Operation Of Three Car Aventras?

Suppose each car in the train was a self-contained power car.

  • Each car could also have  a 75 kWh battery, which is the size of one on a New Routemaster hybrid bus.
  • Regenerative braking would be efficient as it would use the battery in the same car.
  • Batteries can be topped up using the 25 KVAC overhead wires.
  • Passenger services like power-points would be powered from the battery.

If we assume that each car needs 5 kW to do a mile, this would give the train a range away from the wires of 15 miles.

Would it be possible for trains to run on the Camp Hill Line and the proposed Camp Hill Chords into Birmingham Moor Street station solely using battery power?

I think it is possible and after the battery-powered trams on the Midland Metro, it’s another case of emphasising the B in Birmingham.

The Five-Car Aventras

These will probably be vaguely similar to the other two five-car Aventras; Class 701 and Class 720.

Differences highlighted in the various articles and Wikipedia include.

  • According to Wikipedia, the trains will have end gangways.
  • The trains will be 110 mph units.

Both are firsts for Aventras.

I don’t think it will be long before a train operator buys an Aventra capable of 125 mph.

The CAF Civity Trains

The CAF Civity are a mixture of two-car and four-car units and will be used to replace some older diesel multiple units and augment some of the more modern Class 170 and Class 172 trains.

Class 230 Trains

West Midlands Trains have also ordered three Class 230 trains for the Marston Vale Line.

The route has the following characteristics.

  • It is roughly twenty-four miles long.
  • Trains take just over forty minutes for the journey between Bletchley and Bedford stations.
  • There are plans to extend the service to Milton Keynes Central station.
  • It is a diesel island in a sea of electrified lines.

 

Wikipedia says this about the Infrastructure.

Apart from a short length of single track at both ends, the line is double track, and is not electrified (barring short lengths at either end). It has a loading gauge of W8 and a line speed of 60 miles per hour (97 km/h). The line’s signalling centre is at Ridgmont.

I would suspect that two trains are needed to provide an hourly service, so buying three trains gives a spare, that might augment the services at busy times.

The flexibility of the Class 230 trains will give a choice of operating modes.

  • Using 25 KVAC overhead electrification at the ends.
  • Using onboard diesel power.
  • Using batteries charged at the ends of the route.

I suspect that the most efficient will be a mix of all three.

The trains are also designed for remote servicing, so they could be based in a siding at Bedford, Bletchley or Wolverton and supported by a well-designed service vehicle and a fuel bowser.

Conclusions

West Midlands Trains seem to have gone for a sensible Horses-for-Courses solution.

I have a feeling that their concept for the Marston Vale Line will be used elsewhere.

The Intelligent Multi-Mode Train And Affordable Electrification

Some would say we are at a crisis point in electrification, but I would prefer to call it a crossroads, where new techniques and clever automation will bring the benefits of electric traction to many more rail lines in the UK.

Lines That Need Electric Passenger Services

I could have said lines that need to be electrified, but that is probably a different question, as some lines like the Felixstowe Branch Line need to be electrified for freight purposes, but electric passenger services can be provided without full electrification.

Lines include.

  • Ashford to Hastings.
  • Borderlands Line.
  • Caldervale Line from Preston to Leeds
  • Camp Hill Line across Birmingham.
  • Huddersfield Line from Manchester to Leeds via Huddersfield.
  • Midland Main Line from Kettering to Derby, Nottingham and Sheffield.
  • Uckfield Branch Line

There are many others, too numerous to mention.

What Is A Multi-Mode Train?

If a bi-mode train is both electric and diesel-powered, a multi-mode train will have at least three ways of moving.

The Intelligent Multi-Mode Train

The  intelligent multi-mode train in its simplest form would be an electric train with these characteristics.

  • Electric drive with regenerative braking.
  • Diesel or hydrogen power-pack.
  • Onboard energy storage to handle the energy generated by braking.
  • 25 KVAC and/or 750 VDC operation.
  • Automatic pantograph and third-rail shoe deployment.
  • Automatic power source selection.
  • The train would be designed for low energy use.
  • Driver assistance system, so the train was driven safely, economically and to the timetable.

Note the amount of automation to ease the workload for the driver and run the train efficiently.

Onboard Energy Storage

I am sure that both the current Hitachi and Bombardier trains have been designed around energy storage. Certainly, there are several quotes from Bombardier executives that say so.

The first application will be to handle regenerative braking, so that energy can be stored on the train, rather than returned to the electrification.

Onboard energy storage is also important in modern electric trains for other reasons.

  • Features like remote train wake-up can be enabled.
  • Moving the train short distances in case of power failure.
  • When Bombardier started developing the use of onboard energy storage, they stated that one reason was to reduce electrification in depots for reasons of safety.

Onboard energy storage will improve in several ways.

  • The energy density will get higher, meaning lighter and smaller storage.
  • The energy storage capacity will get higher, meaning greater range.
  • The cost of energy storage will become more affordable.
  • Energy storage will last longer before needing replacement.
  • CAF use a supercapacitor to get fast response and a  lithium-ion battery for good capacity.

We underestimate how energy storage will improve over the next few years at our peril.

Automatic Onboard Storage Management

The use of the energy storage will also be optimised for route, passenger load, performance and battery life by the trains automatic power source selection system.

Diesel Power Pack

A conventional diesel power pack to drive the train on lines without electrification.

As the train is electrically-driven, when running under diesel, regenerative braking can still be used, with the generated energy being stored onboard the train.

Hydrogen Power Pack

I believe that hydrogen could be used to generate the electricity required, as it is in some buses.

Operation Of The Multi-Mode Train

I’ve read somewhere that Greater Anglia intend to run their Class 755 trains using electricity, where electrification is available, even if it only for a short distance. This is enabled, by the ability of the train to be able to raise and lower the pantograph quickly and at line speed.

The train’s automatic power source selection will choose the most appropriate power source, from perhaps electrification, stored energy and diesel, based on route, load and the timetable.

Do Any Multi-Mode Trains Exist?

The nearest is probably the Class 800 train, which I believe uses onboard energy storage to handle regenerative braking, as I outlined in Do Class 800/801/802 Trains Use Batteries For Regenerative Braking?.

This article in RailNews is entitled Greater Anglia unveils the future with Stadler mock-up and says this.

The bi-mode Class 755s will offer three or four passenger vehicles, but will also include a short ‘power pack’ car to generate electricity when the trains are not under the wires. This vehicle will include a central aisle so that the cars on either side are not isolated. Greater Anglia said there are no plans to include batteries as a secondary back-up.

So does that mean that Class 755 trains don’t use onboard energy storage to handle regenerative braking?

At the present time, there is no bi-mode Bombardier Aventra.

But in Is A Bi-Mode Aventra A Silly Idea?, I link to an article on Christian Wolmar’s web site, which says that Bombardier are looking into a 125 mph bi-mode Aventra.

My technical brochure for the new Class 769 train, states that onboard energy storage is a possibility for that rebuild of a Class 319 train.

I don’t think it is a wild claim to say that within the next few years, a train will be launched that can run on electric, diesel and onboard stored power.

The Pause Of Electrification

Obviously, for many reasons, electrification of all railway lines is an ideal.

But there are problems.

  • Some object to electrification gantries marching across the countryside and through historic stations.
  • Network Rail seem to have a knack of delivering electrification late and over budget.
  • The cost of raising bridges and other structures can make electrification very bad value for money.

It is for these and other reasons, that the Government is having second thoughts about the direction of electrification.

Is There A Plan?

I ask this question deliberately, as nothing has been disclosed.

But I suspect that not for the first time, the rolling stock engineers and designers seem to be getting the permanent way and electrification engineers out of trouble.

As far as anybody knows, the plan seems to be to do no more electrification and use bi-mode trains that can run under both electrification and diesel-power to provide new and improved services.

Use Of Bi-Mode Trains

Taking a Liverpool to Newcastle service, this would use the electrification to Manchester, around Leeds and on the East Coast Main Line, with diesel power on the unelectrified sections.

If we take a modern bi-mode train like a Class 800 train, some features of the train will help on this route.

  • The pantograph can raise or lower as required at line speed.
  • It is probably efficient to use the pantograph for short sections of electrification.
  • Whether to use the pantograph is probably or certainly should be controlled automatically.

On this route the bi-mode will also be a great help on the fragile East Coast Main Line electrification.

Improving Bi-Mode Train Efficiency

Bi-mode trains may seem to be a solution.

However, as an electrical engineer, I believe that what we have at the moment is rather primitive compared to how the current crop of trains will develop.

Onboard Energy Storage

I said this earlier.

  • I am sure that both the current Hitachi and Bombardier trains have been designed to use energy storage.
  • CAF use a supercapacitor to get fast response and a  lithium-ion battery for good capacity.

This is an extract from the the Wikipedia entry for supercapacitor.

They typically store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver charge much faster than batteries, and tolerate many more charge and discharge cycles than rechargeable batteries.

Supercapacitors are used in applications requiring many rapid charge/discharge cycles rather than long term compact energy storage: within cars, buses, trains, cranes and elevators, where they are used for regenerative braking.

Pairing them with a traditional lithium-ion battery seems to be good engineering.

The most common large lithium-ion batteries in public transport use are those in hybrid buses. In London, there are a thousand New Routemaster buses each with a 75 kWh battery.

In the past, there has have been problems with the batteries on New Routemasters and other hybrid buses, but things have improved and I suspect there is a mountain of knowledge both in the UK and worldwide on how to build a reliable, affordable and safe lithium-ion battery in the 75-100 kWh range.

As on the New Routemaster the battery is squeezed under the stairs, these batteries are not massive and I suspect one or more could easily be fitted underneath the average passenger train.

Look at this picture of a Class 321 train.

The space underneath is typical of many electrical multiple units.

How Far Could A Train Travel On Stored Energy?

In an article in the October 2017 Edition of Modern Railways, which is entitled Celling England By The Pound, Ian Walmsley says this in relation to trains running on the Uckfield Branch.

A modern EMU needs between 3 and 5 kWh per vehicle mile for this sort of service.

So if we take a battery from a New Routemaster bus, which is rated at 75 kWh, this would propel a five-car electric multiple unit between three and five miles.

Suppose though you put a battery of this size in every car of the train. This may seem expensive, but a typical car in a multiple unit and a double-deck bus carry about the same number of passengers.

A battery in each car would give advantages, especially in a Bombardier Aventra.

  • Most cars in an appear to be powered, so each traction motor would be close to a battery, which must reduce electrical transmission losses and ease regenerative braking.
  • Each car would have its own power supply, in case the main supply failed.
  • The weight of the batteries is spread along the train.

If you take any Aventra, with a 75 kWh battery in each car, using Ian’s figures, they would be able to run between fifteen and twenty-five miles on battery power alone.

Quotes by Bombardier executives of a fifty mile range don’t look so fanciful.

What Onboard Energy Storage Capacity Would Be Needed For Fifty Miles?

This article in Rail Engineer, which is entitled An Exciting New Aventra, quotes Jon Shaw of Bombardier on onboard energy storage.

As part of these discussions, another need was identified. Aventra will be an electric train, but how would it serve stations set off the electrified network? Would a diesel version be needed as well?

So plans were made for an Aventra that could run away from the wires, using batteries or other forms of energy storage. “We call it an independently powered EMU, but it’s effectively an EMU that you could put the pantograph down and it will run on the energy storage to a point say 50 miles away. There it can recharge by putting the pantograph back up briefly in a terminus before it comes back.

What onboard energy storage capacity would be needed for the quoted fifty miles?

I will use these parameters.

  • Ian Walmsley said a modern EMU consumes between 3 and 5 kWh for each vehicle mile.
  • All vehicles are powered and there is one battery per vehicle.

This will result in the following battery sizes for different EMU consumption rates.

  • 3 kWh/vehicle-mile – 150 kWh
  • 4 kWh/vehicle-mile – 200 kWh
  • 5 kWh/vehicle-mile – 250 kWh

These figures show that to get a smaller size of battery, you need a very energy-efficient train. At least lighting, air-conditioning and other electrical equipment is getting more efficient.

The 379 IPEMU Experiment On The Mayflower Line

In 2015, I rode the battery-powered Class 379 train on the 11.2 mile long Mayflower Line.

I was told by the engineer monitoring the train on a laptop, that they generally went to Harwich using the overhead electrification, charging the battery and then returned on battery power.

Ian Walmsley in his Modern Railways article says that the batteries on that train had a capacity of 500 kWh.

This works out at just over 11 kWh per vehicle per mile.

Considering this was an experiment conducted on a scheduled passenger service, it fits well with the conssumption quoted in Ian Walmsley’s article.

Crossrail’s Emergency Power

If you look at Crossrail’s Class 345 trains, they are nine cars, with a formation of

DMSO+PMSO+MSO+MSO+TSO+MSO+MSO+PMSO+DMSO

All the Ms mean that eight cars are motored.

Suppose each of the motored cars have a battery of 75 kWh.

  • This means a total installed battery size of 600 kWh.
  • Suppose the nine-car train needs Ian’s Walmsley’s high value of 5 kWh per vehicle mile to proceed through Crossrail.
  • Thus 45 kWh will be needed to move the train for a mile.
  • Dividing this into the battery capacity gives the range of 13.3 miles.

If this were Crossrail’s emergency range on stored energy, it would be more than enough to move the train to the next station or place of safety in case of a complete power failure.

Trains Suitable For Onboard Energy Storage

I have a feeling that for any train to run efficiently with batteries, there needs to be a lot of powered axles and batteries distributed along the train.

Aventras certainly have a lot of powered axles and I think Hitachi trains are similar.

Perhaps this explains, why after the successful trial of battery technology on a Class 379 train, it has not been retrofitted to any other Electrostars.

There might not be enough powered axles!

Topping Up The Onboard Energy Storage

There are three main ways to top up the onboard energy storage.

  • From regenerative braking.
  • From the diesel or hydrogen powerpack.
  • From the electrification, where it is available.

The latter is probably the most efficient and is ideal, where a route is partly electrified.

Affordable Electrification

Although the Government has said that there will be no more electrification, I think there will be selective affordable electrification to improve the efficiency of multi-mode trains.

Why Is Electrification Often Late And Over Budget?

The reasons I have found or been told are varied.

  • Electrification seems regularly to hit unexpected infrastructure like sewers and cables on older routes.
  • There have been examples of poor engineering.
  • There is a large amount of Victorian infrastructure like bridges and stations that need to be rebuilt.
  • There is a certain amount of opposition from the Heritage lobby.
  • Connecting the electrification to the National Grid can be a large cost.

My experience in Project Management, also leads me to believe that although Network Rail seems to plan large station and track projects well, they tend to get in rather a mess with large electrification projects.

Electrification Of New Track

It may only be a personal feeling, but where new track has been laid and it is electrified Network Rail don’t seem to have the same level of problems.

These projects are generally smaller, but also I suspect the track-bed has been well-surveyed and well-built, to give a good foundation for the electrification.

It was interesting to note a few weeks ago at Blackpool, where they are electrifying the line, that Network Rail appeared to be relaying all of the track as well.

I know they were also re-signalling the area, but have Network Rail decided that the best way to electrify the line was a complete rebuild?

Short Lengths Of New Electrification

Short lengths of new electrification could make all the difference on routes using multi-mode trains with onboard energy storage.

As a simple example, I’ll take the Felixstowe Branch Line, that I know well. Ipswwich to Felixstowe is about sixteen miles, which is probably too far for a train running on onboard energy storage. But there are places, where short lengths of electrification would be beneficial to both the Class 755 trains and trains with onboard energy storage.

  • Ipswich to Westerfield
  • On the section of double-track to be built in 2019.
  • Felixstowe station

There is also the large number of diesel-hauled freight trains passing through the area, quite a few of which change to and from electric haulage at Ipswich.

So would some selective short lengths of electrification enable the route to be run by trains using onboard energy storage?

Electrification Of Tunnels

Over the last few years, there has been some very successful electrification of tunnels like the seven kilometre long Severn Tunnel. This is said about the problems of electrification in Wikipedia.

As part of the 21st-century modernisation of the Great Western Main Line, the tunnel was prepared for electrification. It has good clearances and was relatively easy to electrify, although due to its age, the seepage of water from above in some areas provided an engineering challenge. The options of using either normal tunnel electrification equipment or a covered solid beam technology were considered and the decision was made to use a solid beam. Over the length of the tunnel, an aluminium conductor rail holds the copper cable, which is not under tension. A six-week closure of the tunnel started on 12 September 2016. During that time, alternative means of travel were either a longer train journey via Gloucester, or a bus service between Severn Tunnel Junction and Bristol Parkway stations. Also during that time, and possibly later, there were direct flights between Cardiff and London City Airport. The tunnel was reopened on 22 October 2016.

It appears to have been a challenging but successful project.

This type of solid beam electrification has been used successfully by Crossrail and Chris Gibb has suggested using overhead beam to electrify the three tunnels on the Uckfield Branch Line.

In the North of England, there are quite a few long tunnels.

Could these become islands of electrification to both speed the trains and charge the onbosrd energy storage?

Third-Rail Electrification Of Stations

Ian Walmsley in his Modern Railways article proposes using third rail electrification at Uckfield station to charge the onboard energy storage of the trains. He also says this.

This would need only one substation and the third rail could energise only when there is a train on it, like a Bordeaux tram, hence minimal safety risk.

There needs to be some serious thought about how you create a safe, affordable installation for a station.

I also feel there is no need to limit the use of short lengths of third-rail electrification to terminal stations. On the Uckfield Branch, some stations are very rural, but others are in centres of population and/or industry, where electricity to power a short length of third-rail might be available.

Overhead Beams In Stations

This picture shows the Seville trams, which use an overhead beam at stops to charge their onboard energy storage.

Surely devices like these can be used in selective stations, like Hull, Scarborough and Uckfield.

Third-Rail Electrification On Bridges And Viaducts

Some bridges and high rail viaducts like the Chappel Viaduct on the Gainsborough Line, present unique electrification problems.

  • It is Grade II Listed.
  • Would overhead electrification gantries be welcomed by the heritage lobby?
  • It is 23 metres high.
  • Would this height present severe Health and Safety problems for work on the line?
  • The viaduct is 320 metres long.

Could structures like this be electrified using third-rail methods?

  • The technology is proven.
  • As in stations, it could only be switched on when needed.
  • The electrification would not be generally visible.

The only minor disadvantage is that dual-voltage trains would be needed. But most trains destined for the UK market are designed to work on both systems.

Getting Power To Short Lengths Of Electrification

One thing that is probably needed is innovation in powering these short sections of electrification.

Conclusion

There are a very large number of techniques that can enable a multi-mode train to roam freely over large parts of the UK.

It is also a team effort, with every design element of the train, track, signalling and stations contributing to an efficient low-energy train, that is not too heavy.
