TransPennine Express To Stop Using Loco-Hauled Push-Pull Trains In December

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

This is the sub-heading.

TransPennine Express has confirmed that it will cease using its push-pull sets of Class 68 locomotives and MkVa coaches, previously designated Nova 3 sets, from the December 2023 timetable change.

These are my thoughts.

The Nova 3 Trains

Currently, the Nova 3 trains are made up from the following.

Note.

  1. There have been complaints about the noise of the Class 68 locomotives at Scarborough and also at Marylebone with Chiltern Railways.
  2. The Class 68 locomotives could be switched to freight duties.
  3. The coaches are capable of 125 mph.
  4. A maximum of thirteen sets can be created.
  5. I suspect CAF wouldn’t object to being asked to build some more Mark 5a coaches and driving van trailers.
  6. The current fleet has a spare locomotive and a spare driving van trailer to allow for servicing.

All locomotives and coaches are a maximum of seven years old, so will have plenty of life left.

The Class 93 Locomotive

Rail Operations Group have ordered ten Class 93 locomotives, with twenty options, which have an impressive specification.

  • Built by Stadler in Valencia.
  • Same family as a Class 68 and 88 locomotive.
  • Electric, diesel and battery power
  • 110 mph operating speed
  • Ability to pull passenger and freight trains.
  • Delivery scheduled for 2023.

I believe that if the Class 68 diesel locomotive of a Nova 3 train, were to be replaced with a Class 93 locomotive, a very useful train would be created.

  • It would be ten mph faster, than a Nova 3 train.
  • It could use the diesel engine and the batteries to bridge gaps in electrification.
  • By adding extra carriages it could be tailored to the needs of a route.
  • In Vegetable Oil Fuelling Chiltern Railways Trains In UK First, I discuss how it might be possible to run all these locomotives on HVO to cut emissions.
  • It could be quieter.

Could it be a simple way to reduce carbon emissions on a route?

The Successor To The Class 93 Locomotive

Stadler keep innovating in their designs for locomotives and are already building hydrogen-powered multiple units.

I can see Stadler coming up with a hydrogen-powered locomotive, with the following specification.

  • In the same family as Class 68, 88 and 93 locomotives.
  • Ability to do everything that Class 68, 88 and 93 locomotives can do.
  • Ability to use 25 KVAC overhead electrification, where it exists.
  • Ability to be able to be fitted with third-rail equipment, so it can use 750 VDC third-rail electrification, where it exists.
  • At least a 110 mph operating speed.
  • Range of at least 200 miles on hydrogen.

Stadler would sell a lot of these locomotives to decarbonise railways all over the world.

Possible Routes

These are possible routes for a rake of Mark 5a coaches hauled by a Class 93 locomotive or its zero-carbon successor.

Hull Trains

Consider.

  • Hull Trains is an open access operator.
  • Hull Trains currently have a fleet of five Class 802 trains, each of which have five-cars.
  • A Class 93 locomotive has a power of 900 kW on diesel, whereas the Class 802 train has 2100 kW.
  • The Class 802 train has nearly ten percent more capacity.
  • In Ten-Car Hull Trains, I saw two Class 802 trains working as a pair. Does this indicate they have a capacity problem?
  • Between Hull and the East Coast Main Line is only 36.1 miles and  isn’t very challenging and I suspect could probably be easily handled by a Class 93-hauled rake of Mark 5a coaches.
  • Adding extra coaches would not be difficult and would probably be less costly than with the more complex Class 802 trains.
  • Hull Trains need to have a plan to decarbonise.
  • HVO could be used to cut down emissions.

A Class 93-hauled rake of Mark 5a coaches could be an intermediate step  to full decarbonisation with a hydrogen locomotive.

Would other operators of Class 802 trains like to increase their fleets, by adding Hull Trains’s five Class 802 trains?

TransPennine Express

Consider.

  • TransPennine Express currently have four different fleets of trains, so it must cause problems with the allocation of drivers.
  • The Class 397 trains are confined to the West Coast Main Line.
  • So that leaves the bi-mode Class 802 trains and the diesel Class 185 trains to work the TransPennine routes.

The Wikipedia entry for the Class 802 train, gives more details of the plans for the Class 802 trains.

During October 2021, it was announced that TransPennine Express, Hitachi, and Angel Trains had agreed to convert one of the former’s Nova 1 trainsets into a battery hybrid train on a trial basis with the aim of supporting the technology’s further development. If successful, Hitachi and Angel Trains have proposed the retrofitting of the entire fleet. In January 2022, reports emerged that the Nova 1 fleet was operating under diesel power even when operating on entirely electrified sections of the East Coast Main Line on account of the insufficient power supplies present along the line; national railway infrastructure owner Network Rail is reportedly set to complete upgrades to the power supplies within two years.

The fleet is also set to benefit from the rollout of electrification under the Transpennine route upgrade scheme. The company’s management has noted that, in the event of largescale electrification being funded and implemented, the Class 802s could have some of their engines removed to reduce roughly 15% of their weight and thus raise their efficiency. Furthermore, Leo Goodwin, TPE’s managing director, has observed that while the Class 802s have an initial maximum speed of 125 mph (201 km/h), they have the capability of being modified for operating at 140 mph (230 km/h) if infrastructure upgrades were to permit such speeds at a future date.

Could an augmented fleet of battery-electric Class 802 trains handle the bulk of the TransPennine routes, with the shorter and unelectrified ones still being handled by the Class 185 trains?

These shorter routes are.

  • Leeds and Huddersfield
  • Manchester Piccadilly and Huddersfield
  • York and Scarborough

Plans only exist to electrify Leeds and Huddersfield.

I suspect a few more battery-electric Class 802 trains would be needed.

Great Western Railway

Could a Class 93-hauled rake of Mark 5a coaches be used as a replacement for the GWR Castles or short-formation InterCity125s?

  • They both have four passenger coaches.
  • They are both 125 mph trains.
  • A Class 68 locomotive could be used on routes without electrification.
  • HVO could be used to cut down emissions.
  • The Mark 5a coaches would probably be quieter, as they only have one diesel engine.

A Class 93-hauled rake of Mark 5a coaches could be an intermediate step  to full decarbonisation with a hydrogen locomotive.

Alternatively, five-car Class 802 trains could be used as replacements for GWR Castles.

Great Western Railway also have the problem of decarbonising services between Bristol/Gloucester and Weymouth/Southampton/Portsmouth.

Great Western Railway look like they’re needing some innovative thinking.

I also suspect a few more battery-electric Class 802 trains would be needed for other routes.

Transport For Wales Rail

Transport for Wales Rail run a Premier Service between Holyhead and Cardiff using Class 67 locomotives and Mark 4 coaches.

According to the Wikipedia entry for Transport for Wales Rail, they have seven sets of 4/5 coaches to run this service.

If Transport for Wales Rail wanted to decarbonise this route, they would need to replace the locomotives for a zero-carbon unit.

Perhaps, their best solution, would be to wait until a suitable hydrogen-powered locomotive is available and buy seven rakes of new coaches with driving van trailers.

Grand Union

Grand Union has a detailed Wikipedia entry, where this is the first paragraph.

Grand Union is a prospective open access operator who are proposing to operate train services in the United Kingdom from England to Wales and Scotland. Grand Union is headed by Ian Yeowart, who founded previous open access operators Alliance Rail Holdings and Grand Central before selling both to Arriva.

That seems a sound foundation.

  • They have permission to run trains between Paddington and Carmarthen starting in December 2024.
  • They have also applied to run trains between Euston and Stirling.
  • They are now backed by Spanish companies; Serena Industrial Partners and Renfe.
  • They are proposing to use nine Mark 4 coaches hauled by Class 93 locomotives.

Consider.

  • CAF has a factory in Wales.
  • CAF has sold trains to Transport for Wales.
  • The Mark 5a coaches will definitely be available by December 2024.
  • Mark 5a coaches could easily be arranged as a rake of eight coaches and a driving van trailer.
  • Grand Union is backed by Spanish companies.

I wouldn’t be surprised if Grand Union were to use sets of CAF-built Mark 5a coaches for their Carmarthen service. And later for their Stirling service.

A Class 93-hauled rake of Mark 5a coaches could be an intermediate step  to full decarbonisation with a hydrogen locomotive.

Grand Central

Consider.

  • Grand Central is another open access operator.
  • Grand Central has a mixed fleet of twelve five-car diesel trains.
  • These trains run under electrification on the East Coast Main Line.
  • According to the Wikipedia entry for Grand Central trains, they have plans for expansion across the North and to and from London.
  • Grand Central need to have a plan to decarbonise.
  • HVO could be used to cut down emissions.

A Class 93-hauled rake of Mark 5a coaches could be an intermediate step  to full decarbonisation with a hydrogen locomotive.

South Western Railway

South Western Railway have an excellent fleet of new or nearly new trains, with the exception of the diesel Class 158 and Class 159 trains, that work services between Waterloo and Exeter trains via Basingstoke and Salisbury.

  • Waterloo and Exeter is 172 miles.
  • Only the 47.7 miles between Waterloo and Basingstoke is electrified with 750 VDC third-rail electrification.
  • Train lengths vary between five and eight cars.
  • The current trains date from around 1990 and must need replacing soon.

I wouldn’t be surprised that if after a rebranding with new trains, this could be a popular route.

A version of Hitachi’s ubiquitous bi-mode Class 802 could be used.

But.

  • They would need to be ordered and built.
  • The third-rail gear, would need to be developed and tested.
  • Passengers would be travelling for over two and a half hours with underfloor diesel engines.

An alternative could be a Class 68-hauled rake of Mark 5a coaches.

  • These trains would be available after release from TransPennine Express.
  • They would run in TransPennine Express formation.
  • Length could be adjusted by adding or removing coaches, if required.
  • The noise is all in the locomotive, which is isolated from the passengers.

At some point in the future, the route could be decarbonised by swapping the locomotive for a hydrogen-electric locomotive with the ability to handle third-rail electrification.

ScotRail

ScotRail have a similar problem to Great Western Railway with their short-formation InterCity125s.

  • They have 52 Class 43 locomotives and 120 Mark 3 coaches, which is probably enough for 24 trains.
  • Scotland has substantial amounts of electrification.
  • I feel that a Class 68-hauled rake of Mark 5a coaches would be a more than adequate replacement.
  • Class 93 locomotives could be used where routes are partially electrified.
  • Scotland is not going to be short of green hydrogen.

When a suitable hydrogen-electric locomotive is available, these trains can be decarbonised.

CrossCountry

CrossCountry have a fleet consisting of the following trains.

  • 5 – 2+7 InterCity125 trains
  • 7 – two-car Class 170 trains
  • 22 – three-car Class 170 trains
  • 34 – four-car Class 220 trains
  • 4 – four-car Class 221 trains
  • 20 – five-car Class 221 trains

Note.

  1. The fleet is all diesel.
  2. I’ll ignore the Class 170 trains in this analysis.
  3. The Class 220 and 221 trains often work in pairs to provide the required capacity.

So how could these trains be decarbonised?

  • The InterCity125s and the Class 220 and 221 trains could be replaced by a locomotive-hauled rake of Mark 5a coaches of an appropriate length.
  • Motive power could be provided by an appropriate Class 68 or 93 locomotive.

When a suitable hydrogen-electric locomotive is available, these trains can be fully decarbonised.

Decarbonisation Of UK Main Line Services

It is generally assumed that the railways of the UK will need to fully decarbonise if the UK and the constituent nations are going to meet their decarbonisation targets.

I believe that my analysis shows that decarbonisation of main line passenger services can be achieved by the purchase of two types of trains.

  • Five-car bi-mode Class 802 trains or similar.
  • Locomotive-hauled rakes of Mark 5a coaches of an appropriate length.

Note.

  1. The Class 802 trains would be mainly to augment existing Hitachi fleets.
  2. Some Class 802 trains would be fitted with batteries instead of diesel generators to handle gaps in the electrification.
  3. The rakes of coaches would be powered by an appropriate locomotive.
  4. The lengths of the rakes of coaches would be adjusted to meet the demand of each service.

Initially, the following locomotives would be used.

  • Class 68 locomotives would be used on unelectrified lines.
  • Class 93 locomotives would be used on full or partially electrified lines.

When the hydrogen-electric locomotives become available, these would take over the routes, which couldn’t be decarbonised by full electrification or by using a Class 93 locomotive.
