The Anonymous Widower

Kinetic Energy Of A Five-Car Class 801 Train

The standard argument against the bi-mode Class 800 train, was that it would be lugging heavy diesel engines around the country wasting energy.

The Class 801 train is the all-electric version of the Hitachi train.

  • Wikipedia says each coach weighs 41 tonnes.
  • An empty five car train will therefore weigh 205 tonnes.
  • A five-car train seats 315 passengers.
  • If each passenger with baggage, bikes and buggies weighs 90 Kg, this mean they weigh 28.35 tonnes.
  • So the train has a weight of 233.35 tonnes.

Putting this figure into Omni’s Kinetic Engine Calculator gives a kinetic energy of 101.2 kWh.

Five-car Class 801 trains have one underfloor MTU 12V 1600 R80L diesel engine, which weigh seven tonnes, whereas the bi-mode Class 800 trains have three.

The engines have a rating pf 700 kW in the Class 802 trains and are derated to 560 kW in the other  two classes.

So adding engines and repeating the calculation gives.

  • One engine – 104.2 kWh
  • Two engines – 107.2 kWh
  • Three engines – 110.3 kWh

To accelerate a train with three engines to 125 mph will need an extra six kWh compared to a train with only one engine.

There will be a small acceleration penalty. But as three engines have a total power of 1,680 kW (Class 800) or 2,100 kW (Class 802), the penalty would be measured in seconds.

When the train is at the cruising speed of 125 mph, the only difference will be a two tonne difference in axle loading on some axles.

All Class 80x trains will have to overcome the same air resistance and provide similar hotel power., so I’m fairly certain, that all trains will consume very similar amounts of power in the cruise.

Power Comparison With An InterCity 125

Each Class 43 power car of an InterCity 125 has a single diesel engine rated at 1,700 kW.

Divide this by three and you get 566.7 kW

The de-rated MTU diesel engines in the Class 800 train are rated at 560 kW.

So did Hitachi look at the power of half an InterCity 125, feel that they could put diesel engines in three cars of a five-car train and then size the engines to get InterCity 125 power, with two trains working as a pair.

All they would then need to do is to design the cars of the new train to have aerodynamics, dynamics, performance and power usage as good or better than a forty-year-old train.

As they knew that the InterCity 125 had the capabilities needed for the routes, it would mean that their new train would perform, as required.

And if they needed more power for some routes, there was a 700 kW engine available.  Great Western Railway did need some more powerful trains and ordered thirty-six extra Class 802 trains with the larger engine.

If imitation is the sincerest form of flattery, the Japanese have been slowing tremendous respect to the InterCity 125.

Conclusion

It really is extraordinary, that the installed power of two five-car Class 800 trains, is little different to that of an InterCity 125.

The vindication is that both trains work well.

How Much Power Is Needed To Run A Train At 125 mph?

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, which is not very challenging.

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

Can I get any other figures for running at 125 mph, that agree or disagree with these figures?

Class 801 Train

I have found this on this page on the RailUKForums web site.

A 130m Electric IEP Unit on a journey from Kings Cross to Newcastle under the conditions defined in Annex B shall consume no more than 4600kWh.

This is a Class 801 train.

  • It has five cars.
  • Kings Cross to Newcastle is 268.6 miles.
  • Most of this journey will be at 125 mph.
  • The trains have regenerative braking.
  • I don’t know how many stops are included

This gives a usage figure of 3.42 kWh per vehicle mile.

InterCity 125

Note that the Class 43 power cars of the InterCity 125 (HST) put 1,300 kW to the rail and have a 1,700 kW engine. Two of these powerful beasts giving out a total of 3,400 kW,, can sustain a ten-car train (two power cars and eight passenger cars) at 125 mph.

In the thirty seconds, it would take to cover a mile, an HST could use 3400/120 kWh or 28.3 kWh.

Counting the locomotives as a car and dividing by ten gives 2.83 kWh per vehicle mile.

This is actually a maximum figure, as the driver could throttle-back if required.

This figure is not out of line with the 3.42 kWh per vehicle mile for a Class 801 train, that I stated earlier.

The force was with Terry Miller and his team.

Class 222 Train

The Class 222 trains have one 580 kW engine in each car.

In the thirty seconds, it would take to cover a mile, a Class 222 train would use 580/120 or 4.83 kWh per vehicle mile.

Again this must be a maximum figure.

Class 170 Train

The Class 170 train is a 100 mph train with a 315 kW engine in each car.

In the thirty-six seconds, it would take to cover a mile at 100 mph, a Class 170 train would use 315/100 or 3.15 kWh per vehicle.mile.

Again this must be a maximum figure.

Conclusions

I know this was a rather rough and ready calculation, but I can draw two conclusions.

  • Trains running at 125 mph seem to need between three and five kWh per vehicle mile.
  • The forty year old InterCity 125 has an efficient energy use, even if the engines are working flat out to maintain full speed.

The only explanation for the latter is that Terry Miller and his team, got the aerodynamics, dynamics and structures of the InterCity 125 almost perfect. And this was all before computer-aided-design became commonplace.

In future for the energy use of a train running at 125 mph, I shall use a figure of three kWh per vehicle mile.

It is also probably a good starting point for a 100 mph train.

After all, if a forty-year-old diesel-electric train built from steel can achieve that figure, surely a modern electric train built from aluminium can do better!

Speculation Increases Over Use Of HSTs

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

This is the second paragraph.

GWR and ScotRail are both introducing modified four and five-coach HSTs on various duties, with GWR’s operating regional services and ScotRail’s Inter7City sets to be used on its core inter-city routes.

I’ve yet to take a ride in either of the GWR oe Scotrail version of the trains and I shall be looking forward to riding both, later in the year.

I’ve only seem one close-up once at Dundee.

But they seem to be very slow in coming in to service.

Abellio Scotrail’s Proposed Fleet

Abellio Scotrail seem to have 54 Class 43 locomotives and 121 Mark 3 coaches, which according to Wikipedia, will be formed into 26 sets: 17 five-car and 9 four-car trains.

Routes include connecting Scotland’s seven cities.

GWR’s Proposed Fleet

Great Western Railway seem to have retained 24 Class 43 locomotives and 48 Mark 3 coaches, which will be formed into 11 four-car trains.

Routes include between Cardiff and Penzance.

Will These Short HSTs Be Successful?

A number of factors will come into play.

  • The trains are liked by passengers and drivers.
  • They are an ideal size for a lot of routes.
  • They have an excellent ride.
  • They have a lot of capacity for oversized baggage, like bicycles, surf boards, sporting equipment and even some urgent or perishable freight.

Only time will tell, but it is my view, they have a good chance of being a success.

Do Short HSTs Have Any Problems?

The two big problems are their age and that they are diesel-powered I wouldn’t be surprised to see some of the new franchises in the next few years, deciding to go all electric, with only a small number of diesel or hybrid trains.

Would Short HSTs be able to get an exception on heritage grounds?

The technology now is at a level, that by 2030, the UK railways could be diesel-free, with all trains electric, battery or zero-carbon hybrid.

Are There Any Other Routes Where Short HSTs Could Be Used?

I will break them down by franchis, in this incomplete list.

East Midlands Railway – Norwich And Derby

This new route for East Midlands Railway will be created by splitting the current service between Norwich and Liverpool Lime Street stations.

  • The route is 152 miles long.
  • I estimate that current trains will take three hours.
  • The service needs four-car trains at certain times.

Would it be possible for Short HSTs to do a Norwich and Derby round trip in six hours?

GWR – Cardiff And Portsmouth

If the Castles can work Cardiff and Penzance, could they work Cardiff and Portsmouth?

Scotrail – Far North Line

What has surprised me is that Abellio Scotrail are not going to use their Inter7City trains between Inverness and Wick stations on the Far North Line.

  • The distance is 174 miles
  • The current trip takes four and a quarter hours
  • The round trip is nine hours.

So could a short HST do the round trip in eight hours?

A single train could then run to the following schedule.

  • Leave Inverness at 0600.
  • Return from Wick at 1000.
  • Leave Inverness at 1400
  • Return from Wick at 1800

The train would arrive back in Inverness at 2200.

In Is This The Most Unusual Idea For A New Railway Service in The UK?, I wrote about a proposal to introduce Class 230 trains between Wick and Thurso at the far north of Scotland.

This Far North Metro, would sit well with a two train per day service to Inverness.

  • Mark 3 carriages have large windows for sightseeing.
  • A buffet and small bar could be provided.
  • The trains have space for parcels, urgent and perishable freight.
  • The service could link with the ferries to the Orkneys.

A subsidiary objective would be to bring some prosperity to a remote region.

Scotrail – Kyle Of Lochalsh Line

If Short HSTs can work their magic on the Far North Line, I just wonder if they could provide services on the Kyle Of Lochalsh Line.

  • The distance is 83 miles
  • The current trip takes two hours and forty minutes.

So could a short HST do the round trip in six hours?

As with the Far North Line, there would be a much improved service for both those that live along the line and the many visitors.

Transport for Wales – Cardiff And Holyhead

Transport for Wales run a two-hourly service between Cardiff and Holyhead stations. The rolling stock for some services will be a rake of four Mark 4 carriages, a Class 67 locomotive and a driving van trailer.

Isn’t this in effect a train with a similar purpose to a Short HST?

Obviously, Transport for Wales have got good reasons for not running Short HSTs on this route, but the choice of rolling stock does show similar thinking that led to the creation of the Short HST.

Transport for Wales – Heart Of Wales Line

The Heart Of Wales Line runs between Llanelli in West Wales and Craven Arms in England.

  • It is around 150 miles long.
  • Trains take a few minutes over four hours between Swansea and Shrewsbury stations.

It is one of those rail lines, that could be a serious tourism asset.

Would Short HSTs add to the experience?

Transport for Wales -North Wales Main Line

The North Wales Main Line is another line, where iconic Short HSTs might attract passengers.

Conclusion On Routes

There are certainly several places where Short HSTs could be gainfully employed.

Could Any Other Trains Be Used?

The specification could be something like this.

  • Four or five carriages.
  • Diesel, diesel bi-mode or hydrogen bi-mode.
  • Quality interior
  • 100, 110 or 125 mph top-speed.

Trains could be either new build or a rebuilt and/or refurbished older train.

Class 802 Train

Hitachi’s Class 802 train is in service.

  • It meets the specification.
  • It can seat somewhere between 326-342 passengers.
  • It can use electrification if it exists.

It would do a good job.

Class 755 Train

Stadler’s Class 755 train will soon be in service.

  • It meets the specification.
  • It is only a 100 mph train, but I suspect it can be uprated to 125 mph, as the electric version can handle this speed.
  • A four-car train  can seat 227 passengers.
  • It can use electrification if it exists.

It should do a good job.

Could HSTs Have Any Parcel Or Freight Applications?

This is always being suggested, but anything concerning freight or parcels must have the following characteristics.

  • They must be reliable.
  • They must be able to stick to a timetable.
  • They must have a hard-wearing interior, as they will have a hard life.
  • The small single doors would need to be replaced.
  • They must be able to accept standard freight pallets.
  • They must be quick and easy to load.

My biggest worry would be over the last two points. Would the trains just need three much modification to make them suitable for freight and parcels.

Could HSTs Have Heritage Applications?

Already a rake of Mark 3 coaches is going to be used with the  60163 steam locomotive.

But could HSTs in their own right find use in the heritage sector?

I think, that there could be space in the market for a few HSTs, which may have the sort of appeal to the younger generation, that steam trains had to my generation.

After all, I’ve had some of the best meals in my life in an HST.

Conclusion

They may be applications, but each will only use small numbers of trains.

So I’m afraid that some of these trains will go to scrap.

But then no-one can say, that they haven’t done well!

New GWR IETs Under Fire Over Lack Of Buffets

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

This is the first paragraph.

The RMT has been holding demonstrations today at London, Swansea and Plymouth about the lack of buffets on GWR’s new Intercity Express Trains. Surfers have also been protesting about the simultaneous withdrawal of space to carry their boards.

As I don’t even swim, the latter doesn’t bother me and I can’t remember going to the buffet on a GWR train since, I regularly used to go to Reading to see Foster Wheeler in the 1980s. I must admit, that I’ve availed myself of the trolley service.

I have flagged up for some time, that the Class 800, 801 and 802 trains are a bit lacking in the bulky luggage department.

The picture shows an InterCity 125 about to make luggage disappear.

Also in Bicycles And Class 800 Trains, I said this.

I also noticed from the information displays, that all bicycles needed to be booked. That is a bit different from the days of the InterCity 125s, which had lots of space in the back of the locomotive.

On one trip to Plymouth, I saw several surfboards swallowed by the locomotive.

I got in a conversation with a station guy about bicycles and surfboards and from the knowing look on his face, I suspect it is a bit of a pain.

With the growing popularity of cycling, surely a turn up and go regime is needed.

Given that cyclists and surfers may look at the weather and decide, it’s a good time to go cycling or surfing, I suspect that GWR need to come up with a solution to this problem.

In the 1960s, I remember working with a manic surfer; John Baxendale, at ICI in Runcorn. Regularly, at the weekend in the winter, he’d strap his surfboard to the roof of his trusty Morris Minor and drive to the very North of Scotland to go surfing.

Rather him than me!

But if all surfers are like John in the 1960s, they are devoted to their sport and grab all opportunities.

The simplest solution is probably to provide a hire service in Cornwall for bicycles and surfboards.

But the design of the Class 800 trains allows up to twelve cars in a single train.

Could this lead to GWR and/or other operators, adding a tenth car to the trains to handle large luggage and perhaps bring specialist cargo like flowers and seafood up to London? GWR have done this in the past.

Two East Midland Power Cars In Kings Cross

I was surprised to see two East Midlands Class 43 locomotives in Kings Cross station yesterday.

I have noticed an East Midlands-branded set recently and it looks like they have been separated.

Can You Fit These Cases In A Class 800 Train?

I took this picture at Edinburgh station, after arriving there on an Aberdeen to London train.

Could these cases be fitted into a new Class 800 train?

I’ve seen surfboards and heavily-loaded bikes being swallowed by a Class 43 locomotive in an InterCity 125.

Perhaps, passengers with loads like this, will fly to Edinburgh and then use ScotRail’s Inter7City trains around Scotland.

Abellio’s Plans For The Midland Main Line

This page on the Department for Transport web site is an interactive map of the Abellio’s promises for East Midlands Railway.

These are mentioned for Midland Main Line services to Derby, Nottingham and Sheffield.

From May 2020, Modern Diesel Trains Will Begin To Replace Ageing HSTs.

May 2020 is only a year away. Is that enough time to order and build new or refurbish existing diesel trains.

So how will they obtain new trains?

Timetable Changes Will Enable Faster Journey Times From December 2020

These HST-replacement trains must be faster too!

This article on Rail Magazine is entitled Government Seeks Midland Main Line HST Upgrade Update.

It describes how the current eleven HSTs are being updated with retention tanks and accessible toilets, so they can continue to run after this year.

But as the doors won’t be replaced, this means that eleven trains with between six and eight coaches must be found.

One solution mooted is to use Mark 4 Coaches released from LNER, by new Class 801 trains.

In Midland Mark 4, I talk about a possible solution described by Ian Walmsley in the March 2018 Edition of Modern Railways.

  • Two Class 43 power cars would be at each end of a rake of Mark 4 coaches.
  • The current 2+8 formation may need to be shortened to 2+7 because of the heavier coaches.
  • The coaches meet all the regulations.
  • There are plenty of power cars available.

I rode in a Mark 4 coach back from Scotland recently and these will be comfortable trains.

The pictures show First Class, is as good as anything in Europe. The only thing worse, than in Eurostar’s latest Class 374 trains is the space, which is due to our smaller loading gauge.

Not bad for a thirty year old train.

But

  • They were designed for a 140 mph maximum speed.
  • There are 302 coaches of various types available.
  • They meet all current and future accessibility regulations.
  • They have push-button automatic doors.

I estimate that a seven-car set of coaches for the Midland Main Line would have a capacity of around 400-420 passengers in two classes.

As there are currently, eleven InterCity 125 trains working the Midland Main Line, I can’t see there being a shortage of carriages.

Earlier And Later Train Service Each Day To East Midlands Parkway Enabling better Airport Connectivity

iIt won’t affect me, but I suspect other travellers will benefit.

Earlier And Later Trains To And From London, With A More Regular Evening Service Between London And Sheffield

I have moaned about this for a long time.

Try going to Derby or Sheffield from London for an evening football match and getting home that day!

Brand-New 125mph trains Will Be Introduced Into Service From April 2022

Fwatures include.

  • More reliable service
  • Improved comfort
  • Passenger information system
  • Free on-board Wi-Fi
  • At-seat power sockets
  • USB points
  • Air conditioning
  • Tables at all seats
  • increased luggage space
  • On-board cycle storage

I speculate as to who will build them in Hydrogen Trains To Be Trialled On The Midland Main Line.

Stadler’s New Tri-Mode Class 93 Locomotive

In Thoughts On A Battery/Electric Replacement For A Class 66 Locomotive, I looked at an electro-diesel freight locomotive with batteries instead of a diesel engine, as a freight locomotive. It would have the size and weight of a Class 70 locomotive and perhaps use similar technology to Stadler’s Class 88 locomotive.

I concluded the article like this.

It would be a heavyweight locomotive with a performance to match.

I believe that such a locomotive would be a very useful addition to the UK’s fleet of freight locomotives.

Stadler have not produced a battery/electric replacement for a Class 66 locomotive, but they have added a diesel/electric/battery Class 93 locomotive with a heavyweight performance to their Class 68/88 or UKLIGHT family of locomotives built at Valencia in Spain.

Details of the locomotive are given in this article in Rail Magazine, which is entitled Rail Operations Fuels Its Ambitions With Tri-Mode Class 93s. There is also a longerand more detailed  article in the print edition of the magazine, which I purchased today.

Reading both copies of the article, I can say the following.

A More Powerful Class 88 Locomotive

At a first glance, the Class 93 locomotive appears to be a more powerful version of the Class 88 locomotive.

  • The power on electric mode is the same in both locomotives at four megawatt. It would probably use the same electrical systems.
  • Some reports give the diesel power of the Class 93 locomotive as 1.34 MW as opposed to 0.7 MW of the Class 88 locomotive.
  • The Class 93 locomotive has a top speed of 110 mph, as opposed to the 100 mph of the Class 88 locomotive.
  • The article says, “It’s an ’88’ design with the biggest engine we could fit.”

It would also appear that much of the design of the two locomotives is identical, which must make design, building and certification easier.

The Class 93 Locomotive Is Described As A Hybrid Locomotive

Much of the article is an interview with Karl Watts, who is Chief Executive Officer of Rail Operations (UK) Ltd, who have ordered ten Class 93 locomotives. He says this.

However, the Swiss manufacturer offered a solution involving involving an uprated diesel alternator set plus Lithium Titanate Oxide (LTO) batteries.

Other information on the batteries includes.

  • The batteries are used in regenerative braking.
  • Batteries can be charged by the alternator or the pantoraph.
  • Each locomotive has two batteries slightly bigger than a large suitcase.

Nothing is said about the capacity of the batteries, but each could be a cubic metre in size.

I have looked up manufacturers of lithium-titanate batteries and there is a Swiss manufacturer of the batteries called Leclanche, which has this helpful page that compares various batteries.

  • The page gives an energy density of 120-200 Wh/Kg for their traditional lithium-ion batteries and 70-80 Wh/Kg for LTO batteries.
  • But it gives LTO batteries a five-star rating, for charge power, discharge power and energy efficiency.

Leclanche also have a product called a TiRack63, which is intended for industrial applications, such as.

  • ,Grid stabilization in on-grid application
  • Providing short term power to cover the first seconds in a grid failure incident to industrial users.
  • Managing the integration of renewable energy (solar and wind) into off grid applications with diesel generators (e.g. mining),

The battery has the following characteristics.

  • 15000 charge/discharge cycles
  • 100 % depth of discharge.
  • Charging and discharging at 300 Amps.
  • Modular setup.
  • 510-810 VDC output.
  • 63 kWh capacity.
  • Size of 2300 x 1800 x 600 mm
  • Weight of 1800 Kg.

These batteries with their fast charge and discharge are almost like supercapacitors.

, It would appear that, if these batteries are used the Class 93 locomotive will have an energy storage capacity of 126 kWh.

But this is said about Class 93 locomotive performance..

LTO batteries were chosen because they offer a rapid recharge and can maintain line speed while climbing a gradient, and will recharge when running downhill.

Looking at the batteries, they could provide up to around 240 kW of extra power for perhaps half an hour to help the train climb a gradient and then recharge using regenerative braking or the diesel alternator.

This is a hybrid vehicle, with all the efficiency advantages.

The article does say, that with a light load, the locomotives can do 110 mph on hybrid. Nothing is said about what is a light load. Could it be a rake of five modern Mark 5A coaches?

In Thoughts On A Battery Electric Class 88 Locomotive On TransPennine Routes, I said this.

It is worth looking at the kinetic energy of a Class 88 locomotive hauling five forty-three tonne CAF Mark 5A coaches containing a full load of 340 passengers, who each weigh 90 Kg with baggage, bikes and buggies. This gives a total weight would be 331.7 tonnes.

The kinetic energy of the train would be as follows for various speeds.

90 mph – 75 kWh
100 mph – 92 kWh
110 mph – 111 kWh
125 mph – 144 kWh

The increase in energy is because kinetic energy is proportional to the square of the speed.

There would be little difference in this calculation, using a Class 93 locomotive, which is only a tonne heavier. The kinetic energy at 110 mph, would be 112 kWh.

This could be very convenient, as it looks like the battery capacity could be larger than the kinetic energy of a fully-loaded train.

Similar Weight And Axle Load To A Class 88 Locomotive

The article states that the locomotive will weight 87 tonnes, as opposed to the 86 tonnes of a Class 88 locomotive.

As both locomotives have four axles, this would mean that their axle loading is almost the same.

So anywhere the Class 88 locomotive can go, is most likely to be territory suitable for the Class 93 locomotive.

Again, this must make certification easier.

A Modular Design

In a rail forum, members were saying that the Class 93 locomotive has a modular design.

So will we see other specifications with different sized diesel engines and batteries?

The TransPennine routes, for example, might need a locomotive with a smaller diesel engine, more battery capacity and a 125 mph-capability for the East Coast Main Line.

Stadler have said they specialise in niche markets. Have they developed the tailor-made locomotive?

Power Of Various Locomotives

These are various UK locomotives and their power levels in megawatts.

  • Class 43 – Diesel – 1.7
  • Class 66 – Diesel – 2.4
  • Class 67 – Diesel – 2.4
  • Class 68 – Diesel – 2.8
  • Class 88 – Electric – 4
  • Class 88 – Diesel – 0.7
  • Class 90 – Electric – 3.9
  • Class 91 – Electric – 4.8
  • Class 93 – Electric – 4
  • Class 93 – Diesel – 1.3

The interesting figure, is that the Class 93 locomotive has 76 % of the diesel power of a Class 43 locomotive from an InterCity 125. The difference could probably be made up using battery power, where needed.

Could The Locomotive Be Uprated To 125 mph?

Consider.

  • The UK has successfully run 125 mph Class 43 and 91 locomotives for many years.
  • Stadler has built trains that run at that speed.
  • Mark 3, Mark 4 and Mark 5A coaches are all certified for 125 mph.
  • There are hundreds of miles of track in the UK, where 125 mph running is possible.

I would think it very unlikely, that the engineers designing the Class 93 locomotive, ruled out the possibility of 125 mph running in the future!

Only Stadler will know!

Could A Battery/Electric Version Of The Locomotive Be Created?

I don’t see why not!

The diesel engine, fuel, exhaust and cooling systems and some ancilliary systems could all be removed and be replaced with an equivalent weight of batteries.

As the C27 diesel engine in a Class 88 locomotive weighs almost seven tonnes, I suspect a ten tonne battery would be possible.

Given the current typical energy density and using the Leclanche figures, this would mean that thr batteries would have a total capacity of around 700-800 kWh.

Possible Uses Of The Class 93 Locomotive

The Rail Magazine article goes on to detail some of the uses of a Class 93 locomotive.

Express Freight

Karl Watts says this.

They can operate express freight. In Europe, there are vehicles capable of 100 mph running, and these are perfect for high-speed domestic freight. We have been running intermodals at 75 mph since the 1960s – It’s time to change that.

The locomotive would certainly be able to haul express freight at 100 mph on an electrified main line.

Note the following.

  1. This would greatly help with freight between Felixstowe and London on the 100 mph Great Eastern Main Line.
  2. Running freight trains at 100 mph on the major electrified lines would increase capacity, of the lines.
  3. Ports and freight terminals wouldn’t need to be electrified.

Overall, the proportion of freight mileage, where electric power was used, would grow significantly.

Electrification Gap Jumping

In Thoughts On A Battery/Electric Replacement For A Class 66 Locomotive, I gave a list of typical gaps in the electrification in the UK.

  • Didcot and Birmingham – Around two-and-a-half hours
  • Didcot and Coventry – Just under two hours
  • Felixstowe and Ipswich – Around an hour
  • Haughley Junction and Peterborough – Around two hours
  • Southampton and Reading – Around one-and-a-half hours
  • Werrington Junction and Doncaster via Lincoln – Around two hours
  • Werrington Junction and Nuneaton – Just under two hours

How many of these gaps could be bridged by a Class 93 locomotive working in a diesel hybrid mode?

It should be noted, that many of the busiest gaps are in the flatter Eastern areas of England.

I’m sure Stadler and Rail Operations Group have done extensive simulation of possible routes and know where the locomotives are best suited.

Class 66 Locomotive Replacement

I suspect that several of these locomotives will end up replacing duties currently done by Class 66 locomotives.

It could haul an intermodal freight from Felixstowe to Manchester, Liverpool, Glasgow or Doncaster, using electrification where it exists.

And do it at a speed of 100 mph, where speed limits allow!

No other locomotive on the UK network could do that!

Use On Electrified Urban Freight Routes

Near to where I live there are two electrified lines passing through North London; the North London Line and the Gospel Oak To Barking Line.

Both lines have several freight trains a day passing through, that are still hauled by diesel locomotives.

There are other urban freight routes around the UK, where despite electrification, polluting diesel locomotives are still used.

Class 93 locomotives would be an ideal environmentally-friendly replacement locomotive on these routes.

Thunderbird Duties

Karl Watts says this.

They can be used for network recovery as a more comprehensive Thunderbird. Currently, stand-by locomotives are hired or used by an operator to rescue its own trains, but these would be available for anything or anyone. I have sopken to Network Rail about this and they need convincing. But as the network gets busier, so it will be that one failure causes chaos.

Perhaps, a better method for recovering failed trains could be developed.

Passenger Trains

Karl Watts says this.

I can say that the 93s’ feature n two franchise bids, although I cannot say which, due to non-disclosure agreements.

We can only speculate!

Class 93 locomotives could replace the Class 68 locomotives on TransPennine Express services between Liverpool and Scarborough, where Mark 5A coaches will be used.

  • Electric mode could be used between Liverpool and Stalybridge and on the East Coast Main Line.
  • Diesel or hybrid mode would be used where needed.
  • If the locomotives could be uprated to 125 mph, that would help on the East Coast Main Line.

There are certainly, redundant Mark 4 coaches or new Mark 5A coaches that could be used to provide services.

An InterCity 125 For the Twenty-First Century

The InterCity 125 is a masterpiece of engineering, that passengers love.

One of the reasons for the success, is the superb dynamics of the train, which gives them a very comfortable ride.

Could it be that by putting two Class 93 locomotives at each end of a rake of suitable coaches could create a 125 mph train, with the same faultless dynamics?

The answer is probably yes, but in many cases either half-length trains or bi-mode multiple units may be a more affordable or capable train.

The locomotive certainly gives a lot of flexibility.

Conclusion

This is going to be a very useful locomotive.

This was the last paragraph of the printed article, as spoken by Karl Watts.

I don’t think I will be ordering only ten or 20 – there will be more.

I have registered 93001 to 93050.

The word hybrid opens the door.

I think this might be the third member of a very large and widespread family.

Werrington Dive-Under – 8th November 2018

In Issue 865 of Rail Magazine, there is an article, which is entitled NR Primed To Start Work On £200m ECML Dive-Under.

This is said about construction of the dive-under.

Devegetation has already commenced in the area, while work compounds and access roads are due to be constructed before the end of the year (when the main construction sequence is expected to begin).

The dive-under is expected to enter service in 2021.

The article also says that the Cock Lane footbridge will be replaced with a longer truss bridge to span the widened alignment.

These pictures show the current Cock Lane footbridge.

Whilst I took the pictures there was a lot of noise from chain saws and other machinery, as the vegetation was cleared.

The Track Layout

Note how the tracks are divided into a set of two on the Western side and three on the Eastern.

The Western pair are the so-called Stamford lines, which go off to the West through Stamford station.

A diagram in Rail Magazine shows how they will be moved apart and twenty-five metres to the West. This will enable the two new tracks to be laid between them, which will then dive under the East Coast Main Line and connect to the Great Northern Great Eastern Joint Line towards Spalding, Sleaford and Doncaster.

This Google Map shows the Cock Lane Bridge as it crosses the tracks.

The Cock Lane Bridge is at the bottom of the map.

Doing The Work

It looks a simple plan, that NR believes could be executed with a nine-day closure of the East Coast Main Line. This would be needed to tunnel under the three tracks of the main line.

But I suspect that Network Rail could have a series of cunning plans to keep a limited service going.

  • There will probably be a number of bi-mode Class 800 trains available.
  • Some of the sixteen InterCity 125 trains could be retained.

The diesels and bi-modes could be able to use the Great Northern Great Eastern Joint Line and other routes without electrification to sneak through.

They might also use an interim layout of lines at Werrington to keep the service going.

Extra Electrification

It appears to me that not all tracks are electrified.

The Northbound Stamford Line certainly has electrification, but it appears that the Southbound doesn’t.

Given that in the next decade, it is likely that battery/electric or electro-diesel trains or locomotives will use the route throughStamford station to Leicester and Nuneaton, would it be worthwhile to fully electrify the Stamford Lines.

This image captured from a Network Rail video, clearly shows the new Cock Lane footbridge and that the following lines are electrified.

  • The Northbound Stamford Line on the left.
  • The three tracks of the East Coast Main Line on the right.

The actual dive-under and the Southbound Stamford Line appear not to have electrification.

Retention Of Diesel Trains

But surely, if there are a few extra diesel trains around for a couple of years or at least until the end of 2019, would it help to sort out some of the other problems on the East Coast Main Line.

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?
