The Anonymous Widower

Scottish Town Regains Its Station After 56 Years

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

This is the introductory paragraph.

Trains are calling at Kintore in Aberdeenshire today for the first time since December 1964.

Some points about the new Kintore station.

  • It is a two platform station on the newly double-tracked Aberdeen and Inverness Line.
  • The station has a footbridge with lifts.
  • The station is 13.4 miles or 19 minutes from Aberdeen.
  • The station is 94.8 miles or two hours and twenty-three minutes from Inverness.
  • All the services I can find yesterday, seem to have been run by Class 158 trains.
  • There is a 168 space car park, with 24 charging points.

The station cost £15 million.

London Overground Syndrome

I have a feeling that Aberdeen and Inverness Line could be a prime candidate for suffering from London Overground Syndrome.

I suspect though, that ScotRail will quickly eradicate it, by putting on more trains.

Could Battery-Electric Hitachi Trains Work LNER’s Services?

Before I answer this question, I will lay out the battery-electric train’s specification.

Hitachi’s Proposed Battery Electric Train

Based on information in an article in Issue 898 of Rail Magazine, which is entitled Sparking A Revolution, the specification of Hitachi’s proposed battery-electric train is given as follows.

  • Based on Class 800-802/804 trains or Class 385 trains.
  • Range of 55-65 miles.
  • Operating speed of 90-100 mph
  • Recharge in ten minutes when static.
  • A battery life of 8-10 years.
  • Battery-only power for stations and urban areas.
  • Trains are designed to be created by conversion of existing Class 80x trains

For this post, I will assume that the train is five  or nine-cars long. This is the length of LNER‘s Class 800 and 801 trains.

LNER’s Services

These are LNER services that run from London to the North of England and Scotland.

I shall go through all the services and see how they would be affected by Hitachi’s proposed battery-electric Class AT-300 train.

London Kings Cross And Edinburgh

  • The service runs at a frequency of two trains per hour (tph)
  • Some services extend to Aberdeen, Stirling and Inverness and are discussed in the following sections.

This service can be run totally using the existing electrification.

London Kings Cross And Aberdeen

  • The service runs at a frequency of four trains per day (tpd)
  • Intermediate stations are York, Darlington, Newcastle, Berwick-upon-Tweed, Edinburgh, Haymarket, Inverkeithing, Kirkaldy, Leuchars, Dundee, Arbroath, Montrose and Stonehaven.
  • Currently, the electrification goes 394 miles to Haymarket.

The service is 524 miles long and takes seven hours and four minutes.

To ascertain, if the Hitachi’s proposed battery-electric Class AT-300 train, could run this route, I’ll display the various sections of the route.

  • London Kings Cross and Haymarket – 394 miles – Electrified
  • Haymarket and Inverkeithing – 12 miles – Not Electrified
  • Inverkeithing and Kirkcaldy – 13 miles – Not Electrified
  • Kirkaldy and Leuchars – 25 miles – Not Electrified
  • Leuchars and Dundee – 8 miles – Not Electrified
  • Dundee and Arbroath – 17 miles – Not Electrified
  • Arbroath and Montrose – 14 miles – Not Electrified
  • Montrose and Stonehaven – 24 miles – Not Electrified
  • Stonehaven and Aberdeen – 16 miles – Not Electrified

Note.

  1. Haymarket and Dundee is a distance of 58 miles
  2. Dundee and Stonehaven is a distance of 55 miles

So could the service be run with Fast Charge systems at Dundee, Stonehaven and Aberdeen?

I think it could, but the problem would be charging time at Dundee and Stonehaven, as it could add twenty minutes to the journey time and make timetabling difficult on the route.

Perhaps, an alternative would be to electrify a section in the middle of the route to create an electrification island, that could be reached from both Haymarket and Aberdeen.

The obvious section to electrify would be between Dundee and Montrose.

  • It is a distance of 31 miles to electrify.
  • I have flown my virtual helicopter along the route and it could be already gauge-cleared for electrification,
  • Dundee station has been recently rebuilt.
  • Haymarket and Dundee is a distance of 58 miles.
  • Montrose and Aberdeen is a distance of 40 miles.
  • Pantographs could be raised and lowered at Dundee and Montrose stations.

With this electrification and a Fast Charge system at Aberdeen, I believe that Hitachi’s proposed battery-electric Class AT-300 train could run between London Kings Cross and Aberdeen.

As an alternative to the Fast Charge system at Aberdeen, the route of Aberdeen Crossrail between Aberdeen and Inverurie could be electrified.

  • This would enable battery-electric Class 385 trains to run between Inverurie and Montrose.
  • The route through Aberdeen is newly-built, so should be gauge-cleared and reasonably easy to electrify.

It should also be noted that if battery-electric trains can run between Edinburgh and Aberdeen, then these services are also possible, using the same trains.

  • Glasgow and Aberdeen
  • Stirling and Aberdeen

All passenger services  between Scotland’s Cenreal Belt and Aberdeen appear to be possible using battery-electric trains

London Kings Cross And Stirling

  • The service runs at a frequency of one tpd
  • Intermediate stations are York, Darlington, Newcastle, Berwick-upon-Tweed, Edinburgh, Haymarket, Falkirk Grahamstown

This service can be run totally using the existing electrification.

London Kings Cross And Inverness

  • The service runs at a frequency of one tpd
  • Intermediate stations are York, Darlington, Newcastle, Berwick-upon-Tweed, Edinburgh, Haymarket, Falkirk Grahamstown, Stirling, Gleneagles, Perth, Pitlochry, Kingussie and Aviemore.
  • Currently, the electrification goes 429 miles to Stirling, but I have read that the Scottish government would like to see it extended to Perth, which is 462 miles from London.

The service is 581 miles long and takes eight hours and six minutes.

To ascertain, if the Hitachi’s proposed battery-electric Class AT-300 train, could run this route, I’ll display the various sections of the route.

  • London Kings Cross and Haymarket – 394 miles – Electrified
  • Haymarket and Falkirk Grahamsrown – 23 miles – Electrified
  • Falkirk Grahamsrown and Stirling – 11 miles – Electrified.
  • Stirling and Gleneagles – 17 miles – Not Electrified
  • Gleneagles and Perth –  16 miles – Not Electrified
  • Perth and Pitlochry – 28 miles – – Not Electrified
  • Pitlochry and Kingussie – 44 miles – Not Rlectrified.
  • Kingussie and Aviemore – 12 miles – Not Rlectrified.
  • Aviemore and Inverness – 34 miles – Not Electrified

Note.

  1. The distance between Dunblane, where the electrification actually finishes and Perth is only 28 miles, which shouldn’t be too challenging.
  2. All the sections North of Perth are well within range of a fully charged train.
  3. Some sections of the route are challenging. Look at the video I published in Edinburgh to Inverness in the Cab of an HST.
  4. Hitachi run diesel Class 800 trains to Inverness, so they must know the power required and the battery size to run between Perth and Inverness.

I also believe that the Scottish Government, ScotRail, the Highland tourist industry and Hitachi, would all put their endeavours behind a project to get battery-electric trains between Perth and Inverness.

It would send a powerful message, that if battery-electric trains can run on one of the most scenic rail lines in the world without electrification, then nowhere is out of reach of battery trains.

Looking at the figures, I am convinced that a series of Fast Charge systems at stations like Pitlochry, Kingussie and Aviemore could supply enough power to allow a nine-car version of Hitachi’s proposed battery-electric Class AT-300 train to work the route.

This battery-electrification, would also enable battery-electric Class 385 trains to work the route.

If all this sounds a bit fanciful and over ambitious, read the history of the North of Scotland Hydro-Electric Board, which brought electricity to the area in the 1940s and 1950s.

This battery-electrification is a small project compared to what the Hydro-Electric Board achieved.

I can see a time, when similar techniques allow battery-electric trains to run these lines from Inverness.

  • Far North Line – 174 miles
  • Inverness and Kyle of Lochalsh – 82 miles
  • Inverness and Aberdeen – 108 miles

The Far North Line would probably need two or three Fast Charge systems at intermediate stations, but the other lines would probably only need one system, somewhere in the middle.

I think that this analysis for London and Inverness shows that all parts of England, Scotland and Wales can be served by modern battery-electric trains.

It would also appear that the cost of the necessary Fast Charging systems, would be much more affordable than full electrification, North of Perth.

I estimate that less than a dozen Fast Charging systems would be needed, North of Perth.

  • Some electrification might be needed in Inverness station.
  • Electrification between Inverurie and Aberdeen could help.
  • There’s no shortage of zero-carbon electricity from wind and hydro-electric power.

A couple of years ago, I speculated in a post called London To Thurso Direct.

Could it happen on a regular basis in the summer months?

London Kings Cross And Leeds

  • The service runs at a frequency of two tph
  • Intermediate stations are Stevenage, Peterborough, Grantham, Doncaster and Wakefield Westgate

This service can be run totally using the existing electrification.

London Kings Cross And Harrogate

  • The service runs at a frequency of six tpd
  • Intermediate stations are Stevenage, Grantham, Doncaster and Wakefield Westgate
  • Leeds and Harrogate is a distance of nineteen miles and is not electrified.
  • Hitachi’s proposed battery-electric Class AT-300 train should be able to go from Leeds to Harrogate and back, using battery power alone.
  • Batteries will be charged using the electrification at and around Leeds.

This service can be run totally using the existing electrification.

London Kings Cross And Bradford Foster Square

  • The service runs at a frequency of one tpd
  • Intermediate stations are Stevenage, Peterborough, Grantham, Doncaster and Wakefield Westgate
  • Leeds and Bradford Forster Square is a distance of fourteen miles and electrified.

This service can be run totally using the existing electrification.

London Kings Cross And Skipton

  • The service runs at a frequency of one tpd
  • Intermediate stations are Stevenage, Peterborough, Grantham, Doncaster and Wakefield Westgate
  • Leeds and Skipton is a distance of twenty-six miles and electrified.

This service can be run totally using the existing electrification.

London Kings Cross And Lincoln

  • The service runs at a frequency of one train per two hours (1tp2h)
  • Intermediate stations are Stevenage, Peterborough, Grantham and Newark North Gate
  • Newark North Gate and Lincoln is a distance of sixteen miles and not electrified.
  • Hitachi’s proposed battery-electric Class AT-300 train should be able to go from Newark North Gate to Lincoln and back, using battery power alone.
  • Batteries will be charged using the electrification between Newark North Gate and London Kings Cross.

This service can be run totally using the existing electrification.

London Kings Cross And York

  • The service runs at a frequency of 1tp2h
  • Intermediate stations are Stevenage, Peterborough, Grantham and Newark North Gate, Retford and Doncaster

This service can be run totally using the existing electrification.

London Kings Cross And Hull

  • The service runs at a frequency of one tpd
  • Intermediate stations are Stevenage, Peterborough, Grantham and Newark North Gate, Retford and Doncaster
  • Temple Hirst Junction and Hull is a distance of thirty-six miles and not electrified.
  • Hitachi’s proposed battery-electric Class AT-300 train should be able to go from Temple Hirst Junction and Hull and back, using battery power and a Fast Charge system at Hull.
  • Batteries will also be charged using the electrification between Temple Hirst Junction and London Kings Cross.

This service can be run totally using the existing electrification.

Consider.

  • The train runs seventy-two miles to get to Hull and back on lines without electrification..
  • Hitachi state that the trains maximum range on battery power is sixty-five miles.
  • Hull Trains and TransPennine Express also run similar trains on this route, that will need charging at Hull.

So rather than installing a Fast Charge system at Hull, would it be better to do one of the following.

  • Create a battery-electric AT-300 train with a bigger battery and a longer range. A One-Size-Fits-All could be better.
  • However, the larger battery would be an ideal solution for Hull Trains, who also have to reverse and go on to Beverley.
  • Electrify the last few miles of track into Hull. I don’t like this as electrifying stations can be tricky and getting power might be difficult!
  • Electrify between Temple Hirst Junction and Selby station and whilst this is done, build a solution to the problem of the swing bridge. Power for the electrification can be taken from the East Coast Main Line.

I’m sure a compromise between train battery size and electrification can be found, that creates a solution, that is acceptable to the accountants.

Conclusion

I think it could be possible, that LNER could use a fleet of all-electric and battery-electric AT-300 trains.

Are Hitachi Designing the Ultimate Battery Train?

In Sparking A Revolution, a post based on an article of the same name in Issue 898 of Rail Magazine, I repeated this about the specification of Hitachi UK Battery Train Specification.

  • Range – 55-65 miles
  • Performance – 90-100 mph
  • Recharge – 10 minutes when static
  • Routes – Suburban near electrified lines
  • Battery Life – 8-10 years

Does this mean that the train can do 55-65 miles cruising at 90-100 mph?

How Much Energy Is Needed To Accelerate A Five-Car Class 800 Train To Operating Speed?

I will do my standard calculation.

  • Empty train weight – 243 tonnes (Wikipedia for Class 800 train!)
  • Passenger weight – 302 x 90 Kg (Includes baggage, bikes and buggies!)
  • Train weight – 270.18 tonnes

Using Omni’s Kinetic Energy Calculator, the kinetic energy at various speeds are.

  • 60 mph – 27 kWh
  • 80 mph – 48 kWh
  • 90 mph – 61 kWh
  • 100 mph – 75 kWh
  • 125 mph – 117 kWh – Normal cruise on electrified lines.
  • 140 mph – 147 kWh – Maximum cruise on electrified lines.

Because the kinetic energy of a train is only proportional to the weight of the train, but proportional to the square of the speed, note how the energy of the train increases markedly after 100 mph.

Are these kinetic energy figures a reason, why Hitachi have stated their battery train will have an operating speed of between 90 and 100 mph?

A 100 mph cruise would also be very convenient for a lot of main lines, that don’t have electrification in the UK.

What Battery Size Would Be Needed?

In How Much Power Is Needed To Run A Train At 125 mph?, I calculated that a five-car Class 801 electric train, needed 3.42 kWh per vehicle-mile to maintain 125 mph.

For comparison, an InterCity 125 train, had a figure of 2.83 kWh per vehicle-mile.

Hitachi are redesigning the nose of the train for the new Class 804 train and I suspect that these trains can achieve somewhere between 1.5 and 3 kWh per vehicle-mile, if they are cruising at 100 mph.

Doing the calculation for various consumption levels gives the following battery capacity for a five-car train to cruise 65 miles at 100 mph

  • 1.5 kWh per vehicle-mile – 487 kWh
  • 2 kWh per vehicle-mile – 650 kWh
  • 2.5 kWh per vehicle-mile – 812.5 kWh
  • 3 kWh per vehicle-mile – 975 kWh

These figures don’t include any energy for acceleration to line speed from the previous stop or station, but they would cope with a deceleration and subsequent acceleration, after say a delay caused by a slow train or other operational delay, by using regenerative braking to the battery.

The energy needed to accelerate to operating speed, will be as I calculated earlier.

  • 90 mph – 61 kWh
  • 100 mph – 75 kWh

As the battery must have space to store the regenerative braking energy and it would probably be prudent to have a ten percent range reserve, I can see a battery size for a train with an energy consumption of 2 kWh per vehicle-mile, that needed to cruise at 100 mph being calculated as follows.

  • Energy for the cruise – 650 kWh
  • 10% reserve for cruise – 65 kWh
  • Braking energy from 100 mph – 75 kWh

This gives a total battery size of 790 kWh, which could mean that 800 kWh would be convenient.

Note that each of the three MTU 12V 1600 diesel engines, fitted to a Class 800 train, each weigh around two tonnes.

In Innolith Claims It’s On Path To 1,000 Wh/kg Battery Energy Density, I came to these conclusions.

  • Tesla already has an energy density of 250 Wh/Kg.
  • Tesla will increase this figure.
  • By 2025, the energy density of lithium-ion batteries will be much closer to 1 KWh/Kg.
  • Innolith might achieve this figure. But they are only one of several companies aiming to meet this magic figure.

Suppose two of the MTU 12V 1600 diesel engines were each to be replaced by a two tonne battery, using Tesla’s current energy density, this would mean the following.

  • Each battery would have a capacity of 500 kWh.
  • The train would have one MWh of installed battery power.
  • This is more than my rough estimate of power required for a 65 mile trip.
  • The train would have little or no weight increase.
  • I also wouldn’t be surprised to find that the exchange of a diesel engine for a battery was Plug-and-Play.

Hitachi would have an electric/battery/diesel tri-mode train capable of the following.

  • Range – 55-65 miles
  • Out and Back Range – about 20-30 miles
  • Performance – 90-100 mph
  • Recharge – 10 minutes when static
  • Emergency diesel engine.

I feel it would be a very useful train.

Trains That Could Be Fitted With Batteries

The original article in Rail Magazine says this.

For the battery project, positive discussions are taking place with a number of interested parties for a trial, with both Class 385s and Class 800s being candidates for conversion.

So this means that the following operators will be able to use Hitachi’s battery technology o their trains.

  • Avanti West Coast – Class 80x trains
  • First East Coast Trains – Class 80x trains
  • East Midlands Railway – Class 80x trains
  • GWR – Class 80x trains
  • Hull Trains – Class 80x trains
  • LNER – Class 80x trains
  • ScotRail – Class 385 trains
  • TransPennine Express – Class 80x trains

Although, I based my calculations on Class 80x trains, I suspect that the methods can be applied to the smaller Class 385 trains.

Possible Out-And-Back Journeys

These are possible Out-And-Back journeys, that I believe Hitachi’s proposed battery-electric trains could handle.

  • Edinburgh and Tweedbank – 30 miles from Newcraighall
  • London Paddington and Bedwyn – 30 miles from Reading
  • London Euston and Blackburn – 12 miles from Preston
  • London Kings Cross and Bradford – < 27 miles from Leeds
  • London Euston and Chester – 21 miles from Crewe
  • London Kings Cross and Harrogate – <18 miles from Leeds
  • London Kings Cross and Huddersfield – 17 miles from Leeds
  • London St. Pancras and Leicester – 16 miles from Market Harborough
  • London Kings Cross and Lincoln – 17 miles from Newark
  • London St. Pancras and Melton Mowbray – 26 miles from Corby
  • London Kings Cross and Middlesbrough – 20 miles from Northallerton
  • London Kings Cross and Nottingham – 20 miles from Newark
  • London Paddington and Oxford – 10 miles from Didcot
  • London Kings Cross and Redcar – 29 miles from Northallerton
  • London Kings Cross and Rotherham- 14 miles from Doncaster
  • London Kings Cross and Sheffield – 20 miles from Doncaster
  • London and Weston-super-Mare – 19 miles from Bristol

Note.

  1. Provided that the Out-And-Back journey is less than about sixty miles, I would hope that these stations are comfortably in range.
  2. Leicester is the interesting destination, which would be reachable in an Out-And-Back journey. But trains from the North stopping at Leicester would probably need to charge at Leicester.
  3. I have included Blackburn as it could be a destination for Avanti West Coast.
  4. I have included Melton Mowbray as it could be a destination for East Midlands Railway.
  5. I have included Nottingham, Rotherham and Sheffield as they could be destinations for LNER. These services could prove useful if the Midland Main Line needed to be closed for construction works.
  6. I’m also fairly certain, that no new electrification would be needed, although every extra mile would help.
  7. No charging stations would be needed.

I suspect, I’ve missed a few possible routes.

Possible Journeys Between Two Electrified Lines

These are possible journeys between two electrified lines, that  I believe Hitachi’s proposed battery-electric trains could handle.

  • London St. Pancras and Eastbourne via Hastings – 25 miles between Ashford and Ore.
  • Leeds and York via Garforth – 20 miles between Neville Hall and Colton Junction
  • London Kings Cross and Norwich via Cambridge – 54 miles between Ely and Norwich.
  • Manchester Victoria and Leeds via Huddersfield – 43 miles between Manchester Victoria and Leeds.
  • Preston and Leeds via Hebden Bridge – 62 miles between Preston and Leeds.
  • Newcastle and Edinburgh – Would battery-electric trains get round the well-publicised power supply problems on this route?

Note.

  1. I am assuming that a range of 65 miles is possible.
  2. If the trains have a diesel-generator set, then this could be used to partially-charge the battery in places on the journey.
  3. Leeds and York via Garforth has been scheduled for electrification for years.
  4. Preston and Leeds via Hebden Bridge would probably need some diesel assistance.
  5. London Kings Cross and Norwich via Cambridge is a cheeky one, that Greater Anglia wouldn’t like, unless they ran it.
  6. As before no new electrification or a charging station would be needed.

I suspect, I’ve missed a few possible routes.

Possible Out-And-Back Journeys With A Charge At The Destination

These are possible Out-And-Back journeys, that I believe Hitachi’s proposed battery-electric trains could handle, if the batteries were fully charged at the destination.

  • Doncaster and Cleethorpes – 52 miles from Doncaster.
  • London Paddington and Cheltenham – 42 miles from Swindon
  • London Kings Cross and Cleethorpes via Lincoln – 64 miles from Newark
  • London Euston and Gobowen – 46 miles from Crewe
  • London Euston and Wrexham – 33 miles from Crewe
  • London Kings Cross and Hull – 45 miles from Selby
  • London Kings Cross and Shrewsbury – 30 miles from Wolverhampton
  • London Kings Cross and Sunderland 41 miles from Northallerton
  • London Paddington and Swansea – 46 miles from Cardiff
  • London Paddington and Worcester – 67 miles from Didcot Parkway
  • London St. Pancras and Derby – 46 miles from Market Harborough
  • London St. Pancras and Nottingham – 43 miles from Market Harborough

Note.

  1. I am assuming that a range of 65 miles is possible.
  2. If the trains have a diesel-generator set, then this could be used to partially-charge the battery in places on the journey.
  3. I am assuming some form of charging is provided at the destination station.
  4. As before no new electrification would be needed.

I suspect, I’ve missed a few possible routes.

Midland Main Line

The Midland Main Line could possibly be run between London St. Pancras and Derby, Nottingham and Sheffield without the use of diesel.

Consider.

  • The route will be electrified between London St. Pancras and Market Harborough.
  • In connection with High Speed Two, the Midland Main Line and High Seed Two will share an electrified route between Sheffield and Clay Cross North Junction.
  • London St. Pancras and Derby can be run with a charging station at Derby, as Market Harborough and Derby is only 46 miles.
  • London St. Pancras and Nottingham can be run with a charging station at Nottingham, as Market Harborough and Nottingham is only 43 miles.
  • The distance between Clay Cross North Junction and Market Harborough is 67 miles.
  • The distance between Sheffield and Leeds is 38 miles.

It looks to me that the range of East Midlands Railway’s new Class 804 trains, will be a few miles short to bridge the gap on batteries, between Clay Cross North Junction and Market Harborough station, but Leeds and Sheffield appears possible, once Sheffield has been electrified.

There are several possible solutions to the Clay Cross North and Market Harborough electrification gap.

  1. Fit higher capacity batteries to the trains.
  2. Extend the electrification for a few miles North of Market Harborough station.
  3. Extend the electrification for a few miles South of Clay Cross North Junction.
  4. Stop at Derby for a few minutes to charge the batteries.

The route between Market Harborough and Leicester appears to have been gauge-cleared for electrification, but will be difficult to electrify close to Leicester station. However, it looks like a few miles can be taken off the electrification gap.

Between Chesterfield and Alfriston, the route appears difficult to electrify with tunnels and passig through a World Heritage Site.

So perhaps options 1 and 2 together will give the trains sufficient range to bridge the electrification gap.

Conclusion On The Midland Main Line

I think that Hitachi, who know their trains well, must have a solution for diesel-free operation of all Midland Main Line services.

It also looks like little extra electrification is needed, other than that currently planned for the Midland Main Line and High Speed Two.

North Wales Coast Line

If you look at distance along the North Wales Coast Line, from the electrification at Crewe, you get these values.

  • Chester – 21 miles
  • Rhyl – 51 miles
  • Colwyn Bay – 61 miles
  • Llandudno Junction – 65 miles
  • Bangor – 80 miles
  • Holyhead – 106 miles

It would appear that Avanti West Coast’s new AT-300 trains, if fitted with batteries could reach Llandudno Junction station, without using diesel.

Electrification Between Crewe And Chester

It seems to me that the sensible thing to do for a start is to electrify the twenty-one miles between Crewe and Chester, which has been given a high priority for this work.

With this electrification, distances from Chester are as follows.

  • Rhyl – 30 miles
  • Colwyn Bay – 40 miles
  • Llandudno Junction – 44 miles
  • Bangor – 59 miles
  • Holyhead – 85 miles

Electrification between Crewe and Chester may also open up possibilities for more electric and battery-electric train services.

But some way will be needed to charge the trains to the West of Chester.

Chagring The Batteries At Llandudno Junction Station

This Google Map shows Llandudno Junction station.

Note.

  1. It is a large station site.
  2. The Conwy Valley Line, which will be run by battery Class 230 trains in the future connects at this station.
  3. The Class 230 train will probably use some of Vivarail’s Fast Charging systems, which use third-rail technology, either at the ends of the branch or in Llandudno Junction station.

The simplest way to charge the London Euston and Holyhead train, would be to build a charging station at Llandudno Junction, which could be based on Vivarail’s Fast Charging technology or a short length of 25 KVAC overhead wire.

But this would add ten minutes to the timetable.

Could 25 KVAC overhead electrification be erected for a certain distance through the station, so that the train has ten minutes in contact with the wires?

Looking at the timetable of a train between London Euston and Holyhead, it arrives at Colwyn Bay station at 1152 and leaves Llandudno Junction station at 1200.

So would it be possible to electrify between the two stations and perhaps a bit further?

This Google Map shows Colwyn Bay Station,

Note how the double-track railway is squeezed between the dual-carriageway of the A55 North Wales Expressway and the sea.

The two routes follow each other close to the sea, as far as Abegele & Pensarn station, where the Expressway moves further from the sea.

Further on, after passing through more caravans than I’ve ever seen, there is Rhyl station.

  • The time between arriving at Rhyl station and leaving Llandudno Junction station is nineteen minutes.
  • The distance between the two stations is fourteen miles.
  • Rhyl and Crewe is fifty-one miles.
  • Llandudno Junction and Holyhead is forty-one miles.

It would appear that if the North Wales Coast Line between Rhyl and Llandudno Junction is electrified, that Hitachi’s proposed battery trains can reach Holyhead.

The trains could even changeover between electrification and battery power in Rhyl and Llandudno Junction stations.

I am sure that electrifying this section would not be the most difficult in the world, although the severe weather sometimes encountered, may need some very resilient or innovative engineering.

It may be heretical to say so, but would it be better if this section were to be electrified using proven third-rail technology.

West of Llandudno Junction station, the electrification would be very difficult, as this Google Map of the crossing of the River Conwy shows.

I don’t think anybody would want to see electrification around the famous castle.

Electrification Across Anglesey

Llanfairpwll station marks the divide between the single-track section of the North Wales Coast Line over the Britannia Bridge and the double-track section across Anglesey.

From my virtual helicopter, the route looks as if, it could be fairly easy to electrify, but would it be necessary?

  • Llandudno Junction and Holyhead is forty-one miles, which is well within battery range.
  • There is surely space at Holyhead station to install some form of fast-charging system.

One problem is that trains seem to turn round in only a few minutes, which may not be enough to charge the trains.

So perhaps some of the twenty-one miles between Llanfairpwll and Holyhead should be electrified.

London Euston And Holyhead Journey Times

Currently, trains take three hours and forty-three minutes to go between London Euston and Holyhead, with these sectional timings.

  • London Euston and Crewe – One hour and thirty-nine minutes.
  • Crewe and Holyhead – Two hours and four minutes.

The big change would come, if the London Euston and Crewe leg, were to be run on High Speed Two, which will take just fifty-five m,inutes.

This should reduce the London Euston and Holyhead time to just under three hours.

Freight On The North Wales Coast Line

Will more freight be seen on the North Wales Coast Line in the future?

The new tri-mode freight locomotives like the Class 93 locomotive, will be able to take advantage of any electrification to charge their batteries, but they would probably be on diesel for much of the route.

Conclusion On The North Wales Coast Line

Short lengths of electrification, will enable Avanti West Coast’s AT-300 trains, after retrofitting with batteries, to run between Crewe and Holyhead, without using any diesel.

I would electrify.

  • Crewe and Chester – 21 miles
  • Rhyl and Llandudno Junction – 14 miles
  • Llanfairpwll and Holyhead – 21 miles

But to run battery-electric trains between London Euston and Holyhead, only Rhyl and Llandudno Junction needs to be electrified.

All gaps in the electrification will be handled on battery power.

A Selection Of Possible Battery-Electric Services

In this section, I’ll look at routes, where battery-electric services would be very appropriate and could easily be run by Hitachi’s proposed battery-electric trains.

London Paddington And Swansea

Many were disappointed when Chris Grayling cancelled the electrification between Cardiff and Swansea.

I went along with what was done, as by the time of the cancellation, I’d already ridden in a battery train and believed in their potential.

The distance between Cardiff and Swansea is 46 miles without electrification.

Swansea has these services to the West.

  • Carmarthen – 32 miles
  • Fishguard – 73 miles
  • Milford Haven  71 miles
  • Pembroke Dock – 73 miles

It looks like, three services could be too long for perhaps a three car battery-electric version of a Hitachi Class 385 train, assuming it has a maximum range of 65 miles.

But these three services all reverse in Carmarthen station.

So perhaps, whilst the driver walks between the cabs, the train can connect automatically to a fast charging system and give the batteries perhaps a four minute top-up.

Vivarail’s Fast Charging system based on third-rail technology would be ideal, as it connects automatically and it can charge a train in only a few minutes.

I would also electrify the branch between Swansea and the South Wales Main Line.

This would form part of a fast-charging system for battery-trains at Swansea, where turnround times can be quite short.

I can see a network of battery-electric services developing around Swansea, that would boost tourism to the area.

Edinburgh And Tweedbank

The Borders Railway is electrified as far as Newcraighall station and the section between there and Tweedbank is thirty miles long.

I think that a four-car battery-electric Class 385 train could work this route.

It may or may not need a top up at Tweedbank.

The Fife Circle

The Fife Circle service from Edinburgh will always be difficult to electrify, as it goes over the Forth Rail Bridge.

  • The Fife Circle is about sixty miles long.
  • Plans exist for a short branch to Leven.
  • The line between Edinburgh and the Forth Rail Bridge is partly electrified.

I believe that battery-electric Class 385 train could work this route.

London Kings Cross and Grimsby/Cleethorpes via Lincoln

The Cleethorpes/Grimsby area is becoming something of a  renewable energy powerhouse and I feel that battery trains to the area, might be a significant and ultimately profitable statement.

LNER recently opened a six trains per day service to Lincoln.

Distances from Newark are as follows.

  • Lincoln – 17 miles
  • Grimsby – 61 miles
  • Cleethorpes – 64 miles

A round trip to Lincoln can probably be achieved on battery alone with a degree of ease, but Cleethorpes and Grimsby would need a recharge at the coast.

Note that to get to the Cleethorpes/Grimsby area, travellers usually need to change at Doncaster.

But LNER are ambitious and I wouldn’t be surprised to see them dip a toe in the Cleethorpes/Grimsby market.

The LNER service would also be complimented by a TransPennine Express service from Manchester Airport via Sheffield and Doncaster, which could in the future be another service run by a Hitachi battery train.

There is also a local service to Barton-on-Humber, which could be up for improvement.

London Waterloo And Exeter

This service needs to go electric, if South Western Railway is going to fully decarbonise.

But third-rail electrification is only installed between Waterloo and Basingstoke.

Could battery-electric trains be used on this nearly two hundred mile route to avoid the need for electrification.

A possible strategy could be.

  • Use existing electrification, as far as Basingstoke – 48 miles
  • Use battery power to Salisbury – 83 miles
  • Trains can take several minutes at Salisbury as they often split and join and change train crew, so the train could be fast-charged.
  • Use battery power to the Tisbury/Gillingham/Yeovil/Crewkerne area, where trains would be charged – 130 miles
  • Use battery power to Exeter- 172 miles

Note.

  1. The miles are the distance from London.
  2. The charging at Salisbury could be based on Vivarail’s Fast-Charging technology.
  3. The charging around Yrovil could be based on perhaps twenty miles of third-rail electrification, that would only be switched on, when a train is present.

I estimate that there could be time savings of up to fifteen minutes on the route.

Abellio To Lose ScotRail Franchise Three Years Early

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

This is the introductory paragraph.

The ScotRail franchise managed by Abellio will end in March 2022 – some three years earlier than planned, Scottish Transport Secretary Michael Matheson confirmed on December 18.

I don’t live in Scotland, so perhaps I shouldn’t comment too strongly.

  • When I’m in Scotland, I find the performance of ScotRail little different to Greater Anglia, which is also managed by Abellio.
  • In the last three or four years, I have only suffered serious delays a couple of times on Greater Anglia and one was severe weather-related and the other was the usual suspects trying to steal the overhead wires.
  • In that period, I can’t remember being delayed seriously in Scotland.
  • I was also in Scotland for the Commonwealth Games and the rail service coped well with all the visitors.

But Scotland has suffered more than its fair share of Network Rail and train delivery problems.

  • Late delivery of electrification.
  • Poor design of the Borders Railway.
  • Problems with the new Class 385 trains from Hitachi.
  • Problems with the delivery of the Inter7City trains.
  • Disruption caused by the rebuilding of Glasgow Queen Street station.

Is another factor, the endorsement of the SNP in the recent General Election?

I have a feeling that this enforced divorce will be a pension pot for lawyers.

Would It Have Been Better To Scrap HSTs, Abandon Class 769 Trains And Use Stadler Bi-Mode Flirts Instead?

I have ridden for several hours in Greater Anglia'[s new Class 755 trains and they seem to make good trains for scenic rural lines.

From December 16th, we’ll be seeing them work between Stansted and Norwich, which will show their mettle as true bi-modes working a partially-electrified route.

By mid-next year they will be working the following partially-electrified routes.

  • Liverpool Street and Lowestoft
  • Colchester and Peterborough
  • Norwich and Stansted
  • Ipswich and Cambridge
  • Sudbury and Colchester Town

I think that about forty percent of these routes are electrified and they also include a lot of 100 mph lines.

ScotRail

These Greater Anglia routes are not unlike some of the ScotRail Inter7City routes, which are to be run by shorterned four- and five-car HSTs.

Both trains have been late because of training and other issues, but delivery of the HSTs seems to have got stuck round various remanufacturing problems at Wabtec.

Would ScotRail have done better to follow their sister company Greater Anglia and buy some Class 755 trains to their specification?

Consider the advantages of the Inter7City over the Class 755 train.

  • Nostalgia
  • Well-known engineering
  • Comfortable

They could have been obtained at an affordable price.

But they do come with disadvantages.

  • Forty years old
  • Two big diesel engines
  • They are rather dark and dingy inside.

The Class 755 trains also have the following advantages.

  • They would help to remove diesel power from Edinburgh, Glasgow Queen Street and Stirling stations.
  • They have large picture windows ideal for looking at lakes and mountains.
  • Some seats are raised for a better view.
  • They are genuine 100 mph trains, which could be uprated to 125 mph, so would be ideal for incursions on the fast routes to England.
  • They’re probably ready to fit ERTMS.
  • They come in various lengths.
  • They are able to be modified for battery-electric operation.
  • I suspect hydrogen operation will be possible in the future.

But the biggest advantage is that they could extend Scotland’s electric network by using the bi-mode capability.

Think.

  • Fife Circle
  • Borders Railway
  • West Kilbride
  • Perth
  • West Highland Line

I think Scotland could really get to love these trains.

Great Western Railway

I could see a case for running shortened HSTs in the far South West, where GWR call them Castles, mainly on nostalgia and tourism grounds, but Class 755 trains would surely be better running the following partially-electrified services.

  • Henley and Paddington
  • Oxford and Gatwick via Reading
  • Oxford and Paddington
  • Cardiff and Taunton
  • Cardiff and Portsmouth Harbour

Often, they would be replacing Class 156 or Class 769 trains.

  • Some would need to be fitted with third-rail equipment.
  • The Gatwick services could be given an airport interior.
  • I suspect a 125 mph capability is available.
  • The Class 769 trains seem to be late in arriving.

I have no doubt in my mind, that the new Stadler trains are much better than the refurbished British Rail trains.

Transport For Wales

Transport for Wales have ordered a selection of bi-mode and tri-mode Flirts.

They must have good reasons for buying a selection of trains, rather than buying more Flirts.

Probably cost!

All these routes could be run using bi-mode Flirts

  • Cardiff and Holyhead
  • Birmingham International and Holyhead
  • Manchester Airport and Llandudno
  • Crewe and Chester
  • Chester and Liverpool Lime Street
  • Milford Haven and Manchester Piccadilly
  • Birmingham International and Aberystwyth via Shrewsbury
  • Birmingham International and Pwllheli via Shrewsbury
  • Heart of Wales Line
  • Conwy Valley Line

Some of these routes are partially electrified and use lines with a 125 mph operating speed.

Answering The Question In The Title

I very much feel that bi-mode Flirts would be better trains than shortened HSTs and Class 769 trains.

  • They are new trains.
  • They can use electrification, where it is present.
  • The appear to be capable of uprating to 125 mph.
  • They have good viewing for scenic routes because of large windows and some raised seats.
  • They are comfortable with a good ride.
  • They are able to be modified for battery-electric operation.
  • I suspect hydrogen operation will be possible in the future.

I  suspect their one downside is cost.

Conclusion

Bi-mode and tri-mode Flirts and other similar trains will proliferate and within ten years we’ll have seen the last of pure diesel trains in the UK.

I suspect that most of the shortened HSTs will have gone by 2030.

My First Ride In An Inter7City Train

These are some pictures I took of a ride between Edinburgh and Leuchars station.

In some ways, I wasn’t particularly impressed and the interiors were not up to the standard of some InterCity125 trains and Mark 3 coaches I’ve ridden lately.

These are some other pictures of Inter7City trains, I took on my recent trip to Scotland.

They may look nice and are what the public wanted, but would the right new trains have been better.

Scottish Government Approve £75m Levenmouth Rail Link

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

The plan seems to have been well-received by politicians and the media.

I’ve always thought this line to be a good candidate for reopening.

  • It is only five miles long.
  • It would serve Scotland’s largest town without a rail station.
  • There must be freight opportunities for freight, as the line could serve Scotland’s largest distillery.

There is more here on the Wikipedia entry for the Levenmouth Rail Link under Cost, Feasibility And Services.

Could The Levenmouth Rail Link Be Part Of A Bigger Picture?

The Fife Circle Line is an important route into Edinburgh for commuters, shoppers and visitors.

This map from Wikipedia shows the stations on the Fife Circle Line.

Consider.

  • The route is not electrified.
  • A train starting in Edinburgh and going rund the loop would cover about sixty miles.
  • Trains have a frequency of four trains per hour (tph)

It would appear that it would be the sort of service that would be ideal for electric trains, like ScotRail’s Class 385 trains, where a fleet of perhaps eight trains could provide the current service.

But there is a big obstacle to electrification; the Forth Rail Bridge.

It would be a difficult engineering project, that would cause massive disruption and one that would probably be strongly opposed by the Heritage lobby.

This map from Wikipedia shows the proposed Levenmouth Rail Link.

Note how it connects to the Fife Circle Line at Glenrothes with Thorton and Kirkcaldy stations.

I estimate that the distance between Leven and Edinburgh stations would be about 31 miles.

Could Battery-Electric Trains Work To Glenrothes with Thorton And Leven?

Consider these  facts abut battery-electric trains.

  • Bombardier ran a battery-electric train on the 11.5 mile Mayflower Line in public service for three months, without a hitch in 2015.
  • Hitachi, Siemens, Stadler and Vivarail have sold battery-electric trains.
  • Hitachi are running battery-electric trains in Japan.
  • Ranges of upwards of fifty miles are being claimed.
  • Battery-electric trains are a quality experience for passengers.

.As the Edinburgh and Leven and dinburgh and Glenrothes with Thorton routes  are about thirty miles, I believe it is now possible to run battery-electric trains on these two routes.

  • They would be charged at the Edinburgh end using the existing electrification.
  • Charging stations would be needed at Leven and Glenrothes with Thornton.
  • Electrification could also be erected as far as Dalmeny station at the Edinburgh end, which would reduce the range on batteries by about seven miles.

There would be no difficult engineering and the Forth Rail Bridge would look the same as the day it was built!

Hitachi Plans To Run ScotRail Class 385 EMUs Beyond The Wires

I covered this in more detail in Hitachi Plans To Run ScotRail Class 385 EMUs Beyond The Wires.

Hitachi appear to be serious according to this article of the same name on Rail Engineer.

The article concludes with this paragraph.

Hitachi’s proposal to operate battery trains in Scotland is at an early stage. However, with their use being recommended by the rail decarbonisation task force and the Scottish Government about to pass new climate change legislation, it may not be long before battery trains are operating in Scotland.

Hitachi aren’t stupid and I doubt they could want for a better portfolio of launch routes, than some of those in Scotland.

  • Edinburgh and Leven over the Forth Rail Bridge.
  • Edinburgh and Grenrothes with Thornton over the Forth Rail Bridge.
  • The Borders Railway.

I also show in the related article, that Glasgow to Oban and Mallaig may be possible.

The Rail Network And Electrification To The West Of Edinburgh

This map shows the rail system to the West of Edinburgh.

All lines except for the route through South Gyle and Edinburgh Gateway stations are electrified.

Electrification as far as Dalmeny station, the addition of the new chord (shown in yellow) and fill in electrification to join the chord to the Glosgow wires would open up the possibilities of more routes between Edinburgh and Glasgow and a connection between Glasgow and the Fife Circle.

But battery-electric trains would be needed.

ScotRail has Options For More Class 385 Trains

This is said in the Wikipedia entry for the Class 385 trains.

10 unit optional follow up order after 2020.

So ScotRail seem to have a gateway to the future.

Will Battery-Electric Trains Be Good For Tourism?

I very much doubt, that they’ll be bad for it!

Conclusion

The announcement of the reinstatement of the Levenmouth Rail Link, could be be a collateral benefit of a decision to trial or even order some battery-electric Hitachi Class 385 trains.

ScotRail Finds A Use For The Unloved Class 153 Trains

Class 153 trains are the unloved members of British Rail’s Sprinter family. I occasionally use one on excursions to Felixstowe, but they are cramped, noisy and slow.

As the pictures show, some are not in bad condition and to be fair, some train operators have tried hard to provide a better level of service.

Greater Anglia still has five Class 153 trains in service and the fact that they will be replaced by three-car Class 755 trains by the end of 2020. You don’t increase capacity by that amount, unless the current one-car trains are overcrowded or you know that there is a lot of untapped demand on the route.

If on the Felixstowe Branch, a doubling of capacity would have been sufficient, then surely a refurbished two-car Class 150, 156 or 170 train, would have been a more than adequate replacement.

Currently, there are seventy of these trains in service and many of them, like those in East Anglia are being replaced with new or refurbished trains.

Greater Anglia’s five units are going to Wales, where they will join another eight on rural lines in West Wales. Nothing has ben said about how they will be used, but they could be used singly, in pairs or in multiple with Class 15x or Class 17x trains.

So they could be useful to the Welsh in providing extra capacity.

In the November 2018 Edition of Modern Railways, Alex Hynes of ScotRail talks about how a number of Class 153 trains will be used to add bicycle space to trains on some of Scotland’s scenic routes. Alex Hynes is quoted as saying.

The interior format is yet to be fixed, but is likely to include a large amount of space given over to bicycles. Bike tourism is a growing area and the aim would be to allay fears about whether or not you’d get your bike on a train by providing plenty of space. Part of the vehicle might be given over to a lounge car layout to make the most of the magnificent views on these routes.

Transport Scotland sees the scenic routes as a key part of the rural economy for the part they play in stimulating tourism.

Our inspiration is to get “158s” on the West Highland route.

So it looks like ScotRail could be running Class 158/Class 153 pairs to provide increased capacity on the West Highland Line.

Wikipedia says this about the use of the Class 153 trains on the West Highland Line.

These single car units are to be completely adapted to accommodate bikes, skis and other outdoor equipment.

They will be attached to the Class 156s either as centre cars, or as extra coaches at either end.

If ScotRail’s scheme is a success, I suspect more of the Class 153 trains could end up doing the same task, in Wales, the South West and North of England.

It should also be noted, with respect to bicycle tourism, that ScotRail’s shortened HSTs will hopefully retain their bicycle swallowing abilities in the back ends of the power cars, thus enabling bicycle tourists to do the longer Scottish journeys with ease.

My one worry about bicycle tourism in Scotland and Wales is not concerned with trains internally, but with getting there from other parts of the UK with a heavily-loaded bicycle.

With the replacement of the HSTs and InterCity 225 from the London to Edinburgh and London to Wales and the West routes, will the new Class 800 trains have enough bicycle capacity? The bicycle storage on these trains look to be a good design for a racing bicycle, but some of the heavily-loaded bicycle tourists I’ve seen in Suffolk, would find them inadequate.

This article in The Guardian is entitled New High-Speed Trains Go Slow On Provision For Cyclists.

The article is critical.

I wonder what provision has been made for bicycles on the new rolling stock for the Caledonian Sleeper?

ScotRail’s Four-Car High Speed Trains

I took these pictures at Aberdeen station.

Unfortunately, I couldn’t really get any closer.

Looking at the pictures, it appears that the new sliding doors to the coaches have not been fitted.

It also looked as if windows had been added to the sides of one power car. Why?

ScotRail Hires In Class 365s For Glasgow-Edinburgh Route

The title of this post, is the same as thsat of this article on Rail Magazine.

This is the first paragraph.

Three Class 365s have been leased by ScotRail, with more to follow. They will be used on an interim basis on the Edinburgh-Glasgow Queen Street via Falkirk High route while windscreen modifications are made to Class 385s

The Class 365 trains may have been delivered in 1995, but they are no scrapyard specials.

I recently rode one to Cambridge and although some things are dated, the ride is good and they are 100 mph trains, just like the Class 385 trains.

Wikipedia and others reckon that as many as ten trains will go to Crossrail.

How Do The Trains Compare?

The trains are of different generations but how do they compare?

Train Length

On the major route, between Edinburgh and Glasgow, it is intended to run Class 385 trains as seven-car trains formed by a three-car Class 385/0 train

and a four-car Class 385/1 train. As the cars are twenty-three metres long, that gives a train length of 161 metres.

Each four-car Class 365 train is 81.9 metres long, so an eight-car unit would be  just under 164 metres.

I doubt that three metres would cause too many platform-length problems.

Capacity

The capacity of a three-car Class 385/0 is 206 seats, so I suspect a four-car Class 385/1 would seat around 275. This would give a total capacity for the seven-car train of 481 seats.

I can’t find the capacity of a Class 365 train, but it has 2 +2 seating and a fair sprinkling of tables, so I suspect the capacity of the two different formations is not that different.

Operating Speed

Both trains have a 100 mph operating speed.

Passenger Comfort

I suspect that the Class 385 trains will be more to the standard ciustomers expect, wth wi-fi and power sockets and probably more tables.

But the Class 365 trains are one of the better 100 mph long-distance commuter trains, rating above Thameslink’s new Class 700 trains and below the Class 387 train.

Conclusion

The Class 365 trains will make quality substitutes.
