Is Liverpool Going To Get High Speed One-Point-Five?
Some of the best train journeys, I’ve ever had were not on high speed trains on specially-built tracks.
- The Thunder of Three-Thousand Three-Hundred Horses is from the early 1970s and describes a trip back from Darlington behind a Class 55 locomotive or Deltic.
- Norwich-In-Ninety Is A Lot More Than Passengers Think! describes a trip from London to Norwich and back, in the early days of the Norwich-in-Ninety timetable behind a Class 90 locomotive.
- I could add a journey on an InterCity 125 from London to Plymouth, which was running nearly thirty minutes late at Newbury, but was on time at Exeter.
The connection between these stories, was that all had a superb biological control system in the cab, who with help from the signallers was able to keep to a difficult schedule or make up time.
Last year, I made several journeys between Euston and Liverpool Lime Street. A couple of the journeys were unusual in that we arrived at our destination around six or more minutes early.
I suspect, that Avanti West Coast were experimenting to make sure that they get the new two trains per hour (tph) for the route perfect.
In Avanti West Coast Looks To Recover, I said this about Euston and Liverpool Lime Street services.
A paragraph talks about the second hourly service between London and Liverpool.
Avanti still has ambitions to introduce a second hourly service between Euston and Liverpool, but when this will come in will depend on demand recovery.
Consider.
- If would be desirable if some or all trains running on the route could achieve a timing of two hours between London and Liverpool.
- It is felt that the second service should stop at Liverpool South Parkway station, where the platforms are too short for eleven-car Class 390 trains.
- Avanti have stated they would like more stops in the Trent Valley, especially at Nuneaton, where they would connect to services to the East Midlands.
- Nuneaton is almost exactly halfway between London and Liverpool.
- Running two tph with Class 807 trains would need nine trains and Avanti have only ordered ten in total.
I believe that a practical timetable like this could work.
- Class 390 train – one tph – Non-stop or perhaps a single stop in the Midlands – Under two hours
- Class 807 train – one tph – Stopping at Nuneaton, Stafford, Crewe, Runcorn and Liverpool South Parkway – Current time or better
An hourly service between London and Liverpool in under two hours would surely be a passenger magnet.
So what is possible?
I found this service on Real Time Trains, which ran on the 16th February 2023.
- Scheduled to leave Liverpool Lime Street at 0943, but left at 1012 or 29 minutes late.
- Train did a ninety second unadvertised stop at Liverpool South Parkway. Now running 26 minutes late.
- There was a two minute stop at Runcorn and a four-minute stop at Crewe. Now running 25 minutes late
- There was a one-minute stop at Milton Keynes. Now running 20 minutes late.
- The train arrived in London Euston at 1220 or 16 minutes late.
Note.
- Liverpool Lime Street and London Euston took 2 hours and 8 minutes.
- As Liverpool Lime Street and London Euston is a distance of 193.6, a 128 minute journey is an average speed of 90.7 mph
- Liverpool Lime Street and Crewe took 32 minutes with two stops.
- Crewe and London Euston took 1 hour and 32 minutes with one stop.
- In West Coast Main Line Electro-Diesels On Test, I found that a Glasgow and London train took 1 hour and 28 minutes between Crewe and London Euston.
- All services last week had the unadvertised stop at Liverpool South Parkway
What can be deduced from these figures?
- If the Crewe stop were to be cut out, two hours and four minutes could certainly be possible between Liverpool Lime Street and London Euston with a Class 390 train.
- I also suspect that if the train were to be run non-stop, that the other four minutes could be saved.
So will Avanti West Coast run the current service using new Class 807 trains, with the extra stop at Liverpool South Parkway and perhaps other stations and the additional hourly train with a non-stop nine-car Class 390 train?
This way of delivering a two tph service would mean.
- Runcorn, Crewe and Milton Keynes would not lose any of their current fast services to and from Liverpool Lime Street and London Euston.
- Liverpool South Parkway station is probably a more convenient location for some passengers going to and from the South. It would gain an hourly service to London Euston.
- There will be an additional 77% of seats between Liverpool Lime Street and London Euston.
- Passengers who don’t like tilting trains could use the Class 807 trains.
- One tph would be timed for two hours or under and would be a marketing man’s dream.
No train would be slower than the current services.
Improvements To The Non-Stop Class 390 Train Service
I earlier said.
As Liverpool Lime Street and London Euston is a distance of 193.6, a 128 minute journey is an average speed of 90.7 mph.
An average speed of 90.7 mph, doesn’t seem fast for a Class 390 train with an operating speed of 125 mph or 140 mph under full ERTMS digital signalling.
These are some times for a selection of average speeds between Liverpool Lime Street and London Euston.
- 90 mph – 2 hours 9 minutes
- 100 mph – 1 hour 56 minutes
- 110 mph – 1 hour 46 minutes
- 120 mph – 1 hour 37 minutes
- 125 mph – 1 hour 33 minutes
- 130 mph – 1 hour 29 minutes
- 135 mph – 1 hour 26 minutes
- 140 mph – 1 hour 23 minutes
Note.
- Average speeds of upwards of 130 mph are unlikely, but I’ve added them to show that the train speed is less important than the speed of the track.
- High Speed Two’s planned time between Liverpool Lime Street and London Euston is 1 hour and 32 minutes.
But I do think times of around 1 hour and 35 minutes should be possible for non-stop Class 390 trains between Liverpool Lime Street and London Euston with an improved track and full ERTMS digital signalling.
Improvements To The Stopping Class 807 Train Service
As the track of the West Coast Main Line is improved with better track and full ERTMS digital signalling, this will also benefit the times of the stopping service run by the new Class 807 trains.
The Class 807 train with its lighter weight will have better acceleration than the current Class 390 trains. This will mean, that they will not be slowed as much, when they stop.
It may be possible to add extra stops at places like Watford Junction, Nuneaton and Stafford and still time the train for a few minutes over two hours.
Avanti West Coast Looks To Recover, is a post, that I wrote based on an interview in Modern Railways with Phil Whittingham, who is MD of Avanti West Coast.
There is a lot of talk in the article about.
- Using Nuneaton to connect the North West and the East Midlands.
- The acceleration of the Class 807 trains.
- Improving the Customer Service.
I think that Liverpool will find it is connected to more of the country on services with just a single change.
Conclusion
Liverpool is getting greater connectivity to the Midlands and the South-East of England, with times, that could be improved to be comparable with High Speed Two.
Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the two bullet points.
- mtu gensets and cogeneration units to be further developed for 100% hydrogen use
- First use in the new CO2-neutral container terminal in the German inland port of Duisburg
This is the first paragraph.
Rolls-Royce (LSE: RR., ADR: RYCEY) today announces that it has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. The tests, carried out by the Power Systems business unit, showed very good characteristics in terms of efficiency, performance, emissions and combustion. These tests mark another important step towards the commercial introduction of hydrogen solutions to meet the demand of customers for more sustainable energy.
Note.
- Rolls-Royce mtu have converted and tested a natural gas version of the Series 4000 L64 engine.
- The Class 43 power cars used in the iconic InterCity 125 train and powered by mtu V16 4000 R41R engines.
Are the two engines related? If so, can Rolls-Royce mtu build a hydrogen engine that could power an InterCity 125?
It was a rapid development.
Andrea Prospero, an engineer at Rolls-Royce responsible for the development of the hydrogen engine, is quoted as saying.
We are very pleased with the rapid progress. The very low engine emissions are well below the strict EU limits, no exhaust gas aftertreatment is required.
Due to the different combustion behaviour of hydrogen compared to natural gas, some engine components including fuel injection, turbocharging, piston design and control, were modified in the test engine. However, by using proven technologies within the Power Systems’ portfolio, such as mtu turbochargers, injection valves, and engine electronics and control, the development of the engine to use hydrogen was advanced quickly and efficiently.
Diesel and natural gas internal combustion engine manufacturers like Cummins, Rolls-Royce mtu and several other companies, have a long history of research, that they have the knowledge to convert diesel or natural gas engines to hydrogen.
So far only Cummins, JCB and Rolls-Royce mtu have disclosed a multi-fuel line of engines.
First Deployment For CO2-Neutral Power Supply At Duisport
There is a section in the press release called First Deployment For CO2-Neutral Power Supply At Duisport, where this is said.
Duisport, one of the world’s largest inland ports, is working with several partners to build a hydrogen-based supply network for its new terminal, ready for operation in 2024. In the future, most of the electricity required by the port itself will be generated directly on site from hydrogen in a CO2-neutral manner. This will be achieved by two combined heat and power plants with mtu Series 4000 hydrogen engines (with a total installed capacity of 2MW) as well as three mtu fuel cell systems (with a total installed capacity 1.5MW).
As part of its sustainability program, Rolls-Royce is realigning the product portfolio of Power Systems towards more sustainable fuels and new technologies that can further reduce greenhouse gas emissions.
There is also this Rolls-Royce graphic, which shows the energy sources.
It would appear batteries, combined heap and power (CHP), grid electricity, hydrogen electrolyser, hydrogen storage and renewable electricity are being brought together to create a climate-neutral energy system.
Is this a world-first, where hydrogen engines and fuel cell systems will be working together?
Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels
The title of this post, is the same as that of this press release from Rolls-Royce.
The press release starts with these bullet points.
- mtu Series 1300, 1500 and 1800 engines already released; Series 1600 and 4000 to follow shortly
- Up to 90% CO2 savings by operating existing engines with Hydrotreated Vegetable Oil (HVO/renewable diesel)
- Locally emission-free operation possible in combination with mtu Hybrid PowerPack
- Field tests with DB Cargo and RDC Autozug Sylt
Note.
- Hitachi Class 800, 802, 805 and Class 810 trains appear to use Series 1600 engines.
- CAF Class 195, 196 and Class 197 trains appear to use Series 1800 engines.
- Class 43 power cars, as used in InterCity 125 trains appear to use Series 4000 engines.
It would appear that many of the UK’s new diesel trains and the remaining Class 43 power-cars can be converted to run on HVO.
This paragraph from the press release gives more details.
Rolls-Royce is taking a significant step towards even more climate-friendly rail transport with the release of mtu rail engines for use with sustainable fuels. With synthetic diesel fuels of the EN15940 standard, CO2 emissions can be reduced by up to 100 percent compared to fossil diesel. Hydrotreated Vegetable Oil (HVO or renewable diesel), which is already commercially available today, reduces CO2 emissions by up to 90 percent. If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner. The mtu Series 1800 engines which are used in mtu PowerPacks, as well as Series 1300 and 1500 for locomotives and multi-purpose vehicles, are already approved for use with synthetic fuels such as HVO. Series 1600 and versions of Series 4000 engines will follow in the near future. The release of engines for climate-friendly fuels requires a series of tests and trials and Rolls-Royce has found strong partners for this activity. DB Cargo and RDC Autozug Sylt have already tested or are currently testing mtu Series 4000 engines with HVO in their locomotives.
Rolls-Royce mtu seem to have covered all issues.
This is a very significant statement in the paragraph.
If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner.
This must be the most affordable way to make your diesel trains zero carbon.
Conclusion
Rolls-Royce and Cummins seem to be doing a thoroughly professional job in decarbonising the diesel engines they have made in recent years.
It now needs someone to take small diesel engines down the conversion route, just as Rolls-Royce mtu and Cummins are cleaning up their large engines.
Thales Supports Rollout Of UK Digital Railway Programme
The title of this post, is the same as that of this press release from Porterbrook.
The press release starts with these bullet points.
- Thales wins the fitment and supply of European Train Control System (ETCS) onboard units for Class 43 high-speed train retrofit.
- Implementation will benefit passengers and freight operators by delivering additional capacity, improving performance, enhancing safety and reducing the costs of operating the national railway.
Which is followed by this explanation.
As a key player in delivering this digital transformation, Thales has today been awarded the contract for the Class 43 First in Class (FiC) design and fitment project that will use Network Rail’s new measurement train power cars in the Infrastructure Measurement fleet. The FiC project will culminate in a Type approval from the Office of Road and Rail to enable subsequent Class 43 ETCS fleet fitments.
The new Thales onboard system will be integrated as part of the Digital Railway train control system, and will enable rolling stock to operate on ETCS-equipped infrastructure. The onboard equipment is an evolution of Thales’s level 1 ETCS system that has been successfully deployed worldwide.
This could be a smart move.
- Type Approval will mean that the Class 43 power cars of ScotRail’s Inter7Cities, Great Western Railway’s Castles and those of other operators can be retrofitted.
- Will the New Measurement Train also be used to test the digital signalling, as it covers all the tracks in Great Britain in a four-weekly cycle?
- Fitting of these iconic 1970’s designed power cars with the latest modern signalling could be a design exercise, that helps in the fitting of ETCS to other older and unusual locomotives.
I still think, that because of the iconic nature of the InterCity125, that we may see a conversion of Class 43 power cars to more sustainable operation.
- All power cars now have modern MTU diesel engines, which probably could be fuelled by hydrogen.
- The simplest way would be to run them on HVO, as I wrote about in Powered By HVO.
- Some operations like the short format trains in Scotland and South-West England might be more suitable for battery-electric operation.
- Given that there are 167 in operation or in store, it would be a good-sized order for the company converting the power cars.
I also believe that zero-carbon InterCity 125s could be an unusual tourist attraction.
Conclusion
The fitting of digital signalling to Class 43 power cars is a good move, but is it the start of a wider plan to bring these iconic trains up to modern standards.
Union Demands Withdrawal Of All HSTs After Carmont Report
The title of this post, is the same as that of this article on Railnews.
This is the first paragraph.
The TSSA union says it has written to the regulator demanding the immediate withdrawal of all surving HSTs, after new revelations in the Carmont derailment. report.
Manuel Cortes of the TSSA feels that the corrosion problem found in the train that crashed at Carmont, may be present in other trains.
He finishes with this this statement.
Frankly, it’s time to ban the HSTs. They were great in their day, but that day is nearly 50 years ago now and they simply aren’t up to modern safety standards.
I must admit, that I tend to agree with him, on this last point.
Scotrail have the following fleet of Inter7City trains.
- There are 52 Class 43 power cars and 120 Mark 3 coaches, which are arranged as nine four-car and seventeen five-car trains.
- The trains have sliding passenger doors.
- The trains meet all the regulations for Persons of Reduced Mobility.
- The trains have wi-fi and power points.
- They seem to run at up to 100 mph, as against the 125 mph for InterCity 125‘s in the past.
- The power cars have generally been reengined with modern MTU 16V4000 R41R diesel engines.
But they are now on average over forty years old.
In Battery And Hydrogen Trains For ScotRail ‘Could Make Scotland A Global Leader’ In Zero-Emission Transport, which is based on an article in the Scotsman with the same title, I said this.
Other points from the article.
- Talgo appear to have passed the story to Scotland on Sunday.
- Three routes are mentioned; Borders Railway, Fife Circle and Glasgow-East Kilbride.
- The new trains could help phase out diesel trains by 2035, which is Scottish Government policy.
- The Inter7City trains might be replaced by 2030.
- Talgo hopes to win an order for its factory in Fife.
Talgo’s Managing Director is quoted as saying, they are starting testing of a hydrogen and electric train with a range of 311 miles.
Consider.
- I wrote about this train in Talgo To Begin Fuel Cell Loco Trials.
- Talgo’s hydrogen and electric train would be ideal for Scotland’s railways of which only forty percent are electrified.
- A four or five-car high specification hydrogen and electric train would be ideal for the Inter7City routes, if it were built specifically for the routes.
- The range would cover all of Scotland.
- Hydrogen hubs are being planned all over Scotland.
- Scotland have 26 Inter7City trainsets.
This could be a rather nice order to fund the factory and test all the trains close to the factory.
- There could be as many as fifty trains.
- They would probably have an operating speed of 100 mph on electricity.
- Would the speed on hydrogen be 100 mph or perhaps a bit less?
- They would be able to use 25 KVAC overhead electrification, where it exists.
- They could have a length of three, four or five cars.
I wouldn’t be surprised to see three or four car trains for the suburban trains and four or five car trains for the Inter7City replacements.
Will We See Class 43 Power Cars Converted To Hydrogen?
To say that the Class 43 power cars of the InterCity 125 trains are iconic is rather an understatement.
Note.
They were built by British Rail in the late 1970s and early 1980s.
- They have an operating speed of 125 mph.
- They are now powered by a modern MTU 16V4000 R41R diesel engine after being re-engined earlier this century.
- They have an electric transmission.
According to Wikipedia, there are over a hundred and twenty in service.
At the back of the power car there is a lot of space, as this picture shows.
This press release from Rolls-Royce is entitled Rolls-Royce Launches mtu Hydrogen Solutions For Power Generation.
These are the introductory bullet points to the press release.
- From 2022 mtu Series 500 and Series 4000 ready for 25% hydrogen
- From 2023 mtu engines and conversion kits available for 100% hydrogen
And what engine is there in a Class 43 power car? – It’s an MTU 16V4000 R41R diesel engine.
Is it an mtu Series 4000 engine?
If it is, there is space in the back of the power car for the hydrogen tank and the diesel engine can be converted to run on hydrogen, Rolls-Royce have everything they need break the speed record for hydrogen-powered trains. After all power cars; 43102 and 43159 hold the diesel-train speed record at 148 mph.
It would be the ultimate Roller.
Will Zero-Carbon Freight Trains Be Powered By Battery, Electric Or Hydrogen Locomotives?
These are a few initial thoughts.
We Will Not Have A One-Size-Fits-All Solution
If you consider the various freight and other duties, where diesel locomotives are used, you get a long list.
- Light freight, where perhaps a Class 66 locomotive moves a few wagons full of stone to support track maintenance.
- Intermodal freight, where a Class 66 locomotive moves a long train of containers across the country.
- Stone trains, where a Class 59 or Class 70 locomotive moves a very heavy train of aggregate across the country.
- Empty stock movements, where a diesel locomotive moves an electrical multiple unit.
- Supporting Network Rail with trains like the New Measurement Train, which is hauled by two diesel Class 43 power cars.
- Passenger trains at up to and over 100 mph.
I can see a need for several types of zero-carbon locomotive.
- A light freight locomotive.
- A medium freight locomotive, that is capable of hauling many intermodal trains across the country and would also be capable of hauling passenger services.
- A heavy freight locomotive, capable of hauling the heaviest freight trains.
- A Class 43 power car replacement, which would probably be a conversion of the existing power cars. Everybody loves InterCity 125s and there are over a hundred power cars in regular service on railways in the UK.
There are probably others.
The UK Hydrogen Network Is Growing
Regularly, there are news items about companies in the UK, who will be providing green hydrogen to fuel cars, vans, buses, trucks and trains.
Hydrogen is becoming a fuel with a much higher availability.
The UK Electricity Network Is Growing And Getting More Resilient
We are seeing more wind and solar farms and energy storage being added to the UK electricity network.
The ability to support large numbers of battery-electric buses, cars, trucks and trains in a reliable manner, is getting more resilient and much more comprehensive.
There Will Be More Railway Electrification
This will happen and installation will be more innovative. But predicting where electrification will be installed, will be very difficult.
Hydrogen Fuel Cells Now Have Rivals
Hydrogen fuel cells are normally used to convert hydrogen gas to electricity.
But over the last few years, alternative technology has evolved, which may offer better methods of generating electricity from hydrogen.
- Rolls Royce have developed a beer keg-sized 2.5 MW generator, that could run on hydrogen, which I wrote about in Our Sustainability Journey.
- Honeywell are possibly going the same route, which I wrote about in Honeywell Introduces Power Source For Hybrid-Electric Aircraft.
- JCB have converted diesel engines to run on hydrogen, which I wrote about in JCB Finds Cheap Way To Run Digger Using Hydrogen.
- Caterpiller, Cummins and Rolls-Royce mtu are showing signs of taking a similar route to JCB.
Fuel cells will not be having it all their own way.
Batteries Are Improving Their Energy Density
This is inevitable. and you are starting to see improvements in the fabrication of the battery packs to get more kWh into the space available.
In Wrightbus Presents Their First Battery-Electric Bus, I said this about the Forsee batteries used in the new buses from Wrightbus.
The Forsee brochure for the ZEN SLIM batteries gives an energy density of 166 Wh per Kg. This means that the weight of the 454 kWh battery is around 3.7 tonnes.
A one-tonne battery would have a capacity of 166 kWh.
- It is the highest value I’ve so far found.
- Technology is likely to improve.
- Other battery manufacturers will be striving to match it.
For these reasons, in the rest of this post, I will use this figure.
Some Example Locomotives
In this section, I shall look at some possible locomotives.
Conversion Of A Class 43 Power Car
There are two Class 43 power cars in each InterCity 125 train.
- The diesel engine is rated at 1678 kW.
- The transmission is fully electric.
- These days, they generally don’t haul more than five or six intermediate Mark 3 coaches.
I would see that the biggest problem in converting to battery power being providing the means to charge the batteries.
I suspect that these power cars would be converted to hydrogen, if they are converted to zero-carbon.
- I would estimate that there is space for hydrogen tanks and a small gas-turbine generator in the back of the power car.
- Much of the existing transmission could be retained.
- A zero-carbon power car would certainly fit their main use in Scotland and the South-West of England.
- I doubt hydrogen refuelling would be a problem.
They may even attract other operators to use the locomotives.
A Battery-Electric Locomotive Based on A Stadler Class 88 Locomotive
I am using this Class 88 locomotive as a starting point, as the locomotive is powerful, reliable and was built specifically for UK railways. There are also ten already in service in the UK.
In Thoughts On A Battery Electric Class 88 Locomotive On TransPennine Routes, I started the article like this.
In Issue 864 of Rail Magazine, there is an article, which is entitled Johnson Targets A Bi-Mode Future.
As someone, who has examined the mathematics of battery-powered trains for several years, I wonder if the Age of the Hybrid Battery/Electric Locomotive is closer than we think.
A Battery/Electric Class 88 Locomotive
After reading Dual Mode Delight (RM Issue 863), it would appear that a Class 88 locomotive is a powerful and reliable locomotive.
-
- It is a Bo-Bo locomotive with a weight of 86.1 tonnes and an axle load of 21.5 tonnes.
- It has a rating on electricity of 4,000 kW.
- It is a genuine 100 mph locomotive when working from 25 KVAC overhead electrification.
- The locomotive has regenerative braking, when working using electrification.
- It would appear the weight of the diesel engine is around seven tonnes
- The closely-related Class 68 locomotive has a 5,600 litre fuel tank and full of diesel would weight nearly five tonnes.
The locomotive would appear to be carrying between 7 and 12 tonnes of diesel-related gubbins.
Suppose that the diesel-related gubbins of the Class 88 locomotive were to be replaced with a ten tonne battery.
Using the Forsee figures, that I quoted earlier, this battery would hold 1660 kWh.
At the power level of the 700 kW of the Caterpillar C27 diesel engine in the Class 88 locomotive, that would give more than two hours power.
It looks to me, that a battery-electric Class 88 locomotive could be a very useful locomotive.
It might even be able to haul freight trains in and out of the Port of Felixstowe, which would be a big advantage in decarbonising the port.
Certainly, methods to charge battery trains on the move, are being developed like the system from Hitachi ABB Power Grids, that put up short sections of 25 KVAC overhead electrification, which would be driven by a containerised power system.
These systems and others like them, may enable some battery-electric freight trains to work routes like.
- Felixstowe and Ipswich.
- Ipswich and Peterborough
- Peterborough and Nuneaton.
- Peterborough and Doncaster via Lincoln
- Birmingham and Oxford
None of these routes are fully-electrified.
But because of the power limit imposed by the batteries, these locomotives will need to be recharged at points on the route.
This Google Map shows the Ipswich and Peterborough route crossing the Fen Line at Ely station.
Note.
- Ely Dock junction in the South-West corner, where the line from Ipswich and Bury St. Edmunds joins the lines through Ely.
- Ely station towards the North-East corner of the map.
- Passenger trains run through the station.
But freight trains can take a route on the Eastern side of the station, which is not electrified.
At Ely station, a loop like this can be electrified using the existing electrification power supply, but at other places, systems like that from Hitachi ABB Power Grids can be used to electrify the loop or an appropriate section of the route.
These short sections of electrification will allow the train to progress on either electric or battery power.
A Hydrogen-Electric Locomotive Based on A Stadler Class 88 Locomotive
In The Mathematics Of A Hydrogen-Powered Freight Locomotive, I looked at creating a hydrogen-powered locomotive from a Class 68 locomotive.
I decided it was totally feasible to use readily available technology from companies like Rolls-Royce and Cummins to create a powerful hydrogen-powered locomotive.
The Class 68 locomotive is the diesel-only cousin of the electro-diesel Class 88 locomotive and they share a lot of components including the body-shell, the bogies and the traction system.
I suspect Stadler could create a Class 88 locomotive with these characteristics.
- 4 MW using electric power
- At least 2.5 MW using hydrogen power.
- Hydrogen power could come from Rolls-Royce’s 2.5 MW generator based on a small gas-turbine engine.
- 100 mph on both electricity and hydrogen.
- It would have power output on hydrogen roughly equal to a Class 66 locomotive on diesel.
- It would have a range comparable to a Class 68 locomotive on diesel.
This locomotive would be a zero-carbon Class 66 locomotive replacement for all duties.
A Larger And More Powerful Hydrogen-Electric Locomotive
I feel that for the largest intermodal and stone trains, that a larger hydrogen-electric locomotive will be needed.
With the way Wabtec are going in the United States, I wouldn’t be surprised to see a suitable locomotive cross the pond.
Conclusion
In the title of this post, I asked if freight locomotives of the future would be battery, electric or hydrogen.
I am sure of one thing, which is that all freight locomotives must be able to use electrification and if possible, that means both 25 KVAC overhead and 750 VDC third rail. Electrification will only increase in the future, making it necessary for most if not all locomotives in the future to be able to use it.
I feel there will be both battery-electric and hydrogen-electric locomotives, with the battery-electric locomotives towards the less powerful end.
Hydrogen-electric will certainly dominate at the heavy end.
Thoughts On Train Times Between London Paddington And Cardiff Central
I went to Cardiff from Paddington on Tuesday.
These were the journey details.
- Distance – Paddington and Cardiff – 145.1 miles
- Time – Paddington and Cardiff – 110 minutes – 79.1 mph
- Time – Cardiff and Paddington- 114 minutes – 76.4 mph
There were four stops. Each seemed to take between two and three minutes.
I do feel though, that the trains are still running to a timetable, that could be run by an InterCity 125.
I watched the Speedview app on my phone for a lot of both journeys.
- There was quite an amount of 125 mph running on the route.
- Some stretches of the route seemed to be run at a line speed of around 90 mph.
- The Severn Tunnel appears to have a 90 mph speed.
- Coming back to London the train ran at 125 mph until the Wharncliffe Viaduct.
These are my thoughts.
Under Two Hour Service
The current service is under two hours, which is probably a good start.
Improving The Current Service
It does strike me that the current timetable doesn’t take full advantage of the performance of the new Hitachi Class 80x trains.
- Could a minute be saved at each of the four stops?
- Could more 125 mph running be introduced?
- Could the trains go faster through the Severn Tunnel?
- If two trains per hour (tph) were to be restored, would that allow a more efficient stopping pattern?
- The route has at least four tracks between Paddington and Didcot Parkway and the Severn Tunnel and Cardiff.
I would reckon that times of between one hour and forty minutes and one hour and forty-five minutes are possible.
These times correspond to average speeds of between 87 and 83 mph.
Application of In-Cab Digital Signalling
Currently, a typical train leaving Paddington completes the 45.7 miles between Hanwell and Didcot Parkway with a stop at Reading in 28 minutes, which is an average speed of 97.9 mph.
This busy section of the route is surely an obvious one for In-cab digital signalling., which would allow speeds of up to 140 mph.
- Services join and leave the route on branches to Bedwyn, Heathrow, Oxford and Taunton.
- The Heathrow services are run by 110 mph Class 387 trains.
- There are slow lines for local services and freight trains.
If an average speed of 125 mph could be attained between Hanwell and Didcot Parkway, this would save six minutes on the time.
Would any extra savings be possible on other sections of the route, by using in-cab digital signalling?
I suspect on the busy section between Bristol Parkway and Cardiff Central stations several minutes could be saved.
Would A Ninety Minute Time Between Paddington And Cardiff Be Possible?
To handle the 145.1 miles between Paddington and Cardiff Central would require an average speed including four stops of 96.7 mph.
This average speed is in line with the current time between Hanwell and Didcot Parkway with a stop at Reading, so I suspect that with improvements to the timetable, that a ninety minute service between Paddington and Cardiff Central is possible.
It may or may not need in-cab digital signalling.
My Control Engineer’s nose says that this signalling upgrade will be needed.
Would A Sixty Minute Time Between Paddington And Cardiff Be Possible?
A journey time of an hour between Paddington and Cardiff Central would surely be the dream of all politicians the Great Western Railway and many of those involved with trains.
To handle the 145.1 miles between Paddington and Cardiff Central would require an average speed including four stops of 145.1 mph.
It would probably be difficult to maintain a speed a few mph above the trains current maximum speed for an hour.
- How many minutes would be saved with perhaps a single intermediate stop at Bristol Parkway station?
- Perhaps the Cardiff service could be two tph in ninety minutes and one tph in sixty minutes.
- Full in-cab digital signalling would certainly be needed.
- Faster trains with a maximum speed of up to 155-160 mph would certainly be needed.
- There may be a need for some extra tracks in some places on the route.
A journey time of an hour will be a few years coming, but I feel it is an achievable objective.
The Extended Route To Swansea
Cardiff Central and Swansea is a distance of 45.7 miles
A typical service takes 55 minutes with three stops, at an average speed of 49.8 mph.
This would be an ideal route for a Hitachi Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.
It would probably be needed to be charged at Swansea station, to both enable return to Cardiff Central or extend the service to the West of Swansea.
Conclusion
Big improvements in journey times between Paddington and Cardiff Central are possible.
My First Ride In A Class 769 Train
I went to Cardiff today and had my first ride in a Class 769 train. These pictures summarise my ride on the train between Cardiff Central and Bargoed stations.
So what was it like?
Noise And Vibration
Going up to Bargoed, I deliberately sat as near over the top of the engine as I could.
There was a bit of a whine, but not as much as in a new Class 195 train.
For those, who commuted on Class 319 trains for years on Thameslink, they probably wouldn’t notice much difference.
Performance
For a 100 mph electric train built for running between the flat lands of Bedfordshire and the South Coast over the hillocks of the Downs, the train climbed to Bengoed, which has an altitude of around a thousand feet with a purpose.
But then I have a Porterbrook brochure for these trains and the power source was sized, such that the train would be able to climb the stiffest routes in the UK.
The Interior
It looked to me like the Thameslink interior with new sea covers and plugs to charge a mobile phone.
They could certainly be upgraded a bit further to the standard of the Class 319 trains on the Abbey Line, that I wrote about in A Very Smart Class 319 Train.
A Job To Do
Trains for Wales has acquired these trains for extra capacity, whilst they refurbish their Class 150, 153 and 160 trains.
It looks to me, that they will do this job more than adequately.
Future Uses
I suspect Porterbrook hope that these trains will find uses around the UK, as they have spent a lot of time, effort and money to bring these trains into service.
But there are around eighty of the Class 319 trains in service or in store, from which the Class 769 trains are converted.
So they could find uses in several niche applications.
Short Term Fleets
This is effectively, the Trains for Wales application, where extra trains are provided, so that a fleet refurbishment can be performed.
- They would surely, have been a better replacement fleet for Greater Anglia, than the three Mark 2 coaches and a pair of diesel locomotives, that they used after a series of level crossing accidents.
- They could also be used to increase capacity for some major events like the Open Golf or a pop festival.
- Uniquely, they can stand in for both a 100 mph electric train or a 90 mph diesel train.
- They can even be fitted with third-rail shoes.
- They are the right size at four cars.
- They fit most UK platforms.
- They can be run in formations of up to twelve cars.
I wouldn’t be surprised to see Porterbrook or someone on their behalf, keep a fleet of trains on standby to handle short term needs.
Route Development And Testing
There has been a lot of pressure to open up new routes in recent years and these trains would be ideal to try out routes and test new electrification.
Tri-Mode Services
Great Western Railway have a particular problem with their service between Reading and Gatwick, in that it has some third-rail electrification. As they might like to extend this service to Oxford, an ideal train would be dual-voltage and self-powered.
This extract is from the Great Western Railway section in the Wikipedia entry for the Class 769 train.
Although initially planned for use in London and the Thames Valley whilst twelve Class 387 units are modified for Heathrow Express services, the future plan for these units will be operating on services between Oxford, Reading and Gatwick Airport, which would mean operating on unelectrified, 25 kV AC OHLE and 750 V DC third-rail routes. To enable this, Great Western Railway’s allocation of Class 769 units will retain their dual-voltage capability in addition to being fitted with diesel power units. The units will also receive an internal refurbishment and be fitted with air cooling.
I suspect, that they’ll also be used on the Henley, Marlow and Windsor branches, which have some operational problems.
- The branches are not electrified.
- Some branches run occasional services to Paddington.
- The Windsor branch probably needs more capacity.
The Marlow branch could be difficult, but I suspect that, there’s a solution somewhere.
Luxury Bi-Modes
Greater Anglia felt they needed luxury bi-modes for East Anglia and they bought Class 755 trains, which are probably a lot more expensive, as they are brand-new and from Stadler of Switzerland.
Surprisingly, the Class 319 trains have a higher passenger capacity.
But both trains could do a similar task, where the route is partially electrified.
As I said earlier about the GWR units.
The units will also receive an internal refurbishment and be fitted with air cooling.
Porterbrook’s brochure for the Class 769 train talks about using them between Manchester and Buxton.
Surely, this route could do with a Northern version of a GWR interior.
I also think a service should link Hellifield and Buxton. as I wrote about in Why Not Buxton To Hellifield?
That would show what Class 769 trains could do!
It would also connect the Peak District to the hills North of Lancashire.
I might also be, that the standby-fleet should also be the luxury variant of the train. Surely, supporters going to the Open at some of the inaccessible venues could afford pay to pay extra for a comfy train.
Express Freight And Parcels Services
Rail Operations Group would appear to have placed the second-largest order for Class 769 trains, which they will use to launch a high-speed parcels service called Orion.
This extract is from the Rail Operations Group section in the Wikipedia entry for the Class 769 train.
Orion is aiming to launch its first trial service conveying parcels and light freight in April 2021, with the Midlands to Mossend now likely to be the debut flow. The company is to use converted Class 319s for the service and is now planning for a fleet of 19 four-car units – nine Class 319s and 10 Class 769s. Arlington Fleet Services at Eastleigh is modifying the interiors of the units to accommodate roller cages for parcels, with the aim of operating primarily under electric power but with the 769s using their diesel engines to act as tractor units for the 319s on non-electrified stretches. The first 769 bi-mode, No 769501, has undergone its Flex conversion at Brush in Loughborough and is due to be outshopped from Arlington at Eastleigh in March following its interior modification.
In Did These Strawberries Have Road- Or Rail-Miles?, I talked about strawberries going between Scotland and London.
Surely, the movement of high-quality food could be one of the cargoes for Orion.
It wouldn’t be the first such traffic, as Class 43 power cars of the InterCity 125s used to carry flowers and fish up to London from Cornwall.
There’s a lot of space in the back of a Class 43 power car.
I certainly feel there are possibilities for using Class 769 trains as high speed parcels transport.
It should be noted that Class 325 trains already run high speed parcel services up and down the country on behalf of Royal Mail. These trains may look like later British Rail trains, but they are in fact based on Class 319 trains.
So I doubt, there’ll be any worries that the trains can’t handle the required services after conversion.
Conclusion
It looks to me that Porterbrooks plan to convert numbers of their Class 319 trains into Class 769 trains will find several ready markets.
It could be argued that more carbon savings could be achieved by perhaps a new battery-electric or hydrogen-electric train. But these will take years to develop!
These trains are a good short-term solution, that will help define their zero-carbon successors.
Through Settle And Carlisle Service Under Consideration
The title of this post, is the same as that of an article in the June 2021 Edition of Modern Railways.
This is the first paragraph.
Plans for a new Leeds to Glasgow through service via the Settle and Carlisle line are being developed, with CrossCountry and the Department for Transport starting to look at the possible scheme.
It sounds like a sensible idea to me.
The article also suggests the following.
- CrossCountry is a possible operator.
- CrossCountry are keen to improve services between Leeds and Glasgow
- The trains could be InterCity 125s, freed up, by a the arrival of Class 221 trains from Avanti West Coast, when they receive their new Class 805 trains.
- Maintenance of the trains wouldn’t be a problem, as this could be done at Neville Hill in Leeds or Craigentinny in Edinburgh.
- Services could start in December 2023.
I have a few thoughts of my own!
The Route
The route between Leeds and Carlisle is obvious, but there are two routes between Carlisle and Glasgow.
Trains would probably choose a route and call at stations to maximise passenger numbers.
These stations are on the various routes.
- Settle and Carlisle – Shipley, Bingley, Keighley, Skipton, Gargrave, Hellifield, Long Preston, Settle, Horton in Ribblesdale, Ribblehead, Dent, Garsdale, Kirkby Stephen, Appleby, Langwathby, Lazonby & Kirkoswald and Armathwaite
- Glasgow South Western – Dunlop, Stewarton, Kilmaurs, Kilmarnock, Auchinleck, New Cumnock, Kirkconnel, Sanquhar, Dumfries, Annan and Gretna Green
- West Coast Main – Motherwell, Carstairs and Lockerbie
There are certainly a lot of possibilities.
Upgrading The InterCity 125 Trains
CrossCountry appear to have enough InterCity 125 trains to muster five in a two Class 43 power car and seven Mark 3 coach formation.
They may not be fully in-line with the latest regulations and there may be a need for a certain degree of refurbishment.
These pictures show some details of a refurbished Great Western Railway Castle, which has been fitted with sliding doors.
Will The InterCity 125 Trains Be Shortened?
Scotrail’s Inter7City trains and Great Western Railway’s Castle trains have all been shortened to four or five coaches.
This picture shows a pair of Castles.
Journey Times, Timetable And Frequency
The current journey time between Leeds and Glasgow Central stations via the East Coast Main Line is four hours and eight minutes with nine stops.
The Modern Railways article says this about the current service.
The new service would be targeted at business and leisure travellers, with through journey times competitive with road and faster than the current direct CrossCountry Leeds to Glasgow services via the East Coast main line.
I would expect that CrossCountry are looking for a time of around four hours including the turn round.
- Stops could be removed to achieve the timing.
- The trains could run at 125 mph on the West Coast Main Line.
This could enable a train to have the following diagram.
- 0800 – Depart Leeds
- 1200 – Depart Glasgow Central
- 1600 – Depart Leeds
- 2000 – Depart Glasgow Central
- Before 2400 – Arrive Leeds
Note.
- A second train could start in Glasgow and perform the mirrored timetable.
- Timings would probably be ideal for train catering.
- Trains would leave both termini at 0800, 1200, 1600 and 2000.
- The timetable would need just two trains.
I also think, if a second pair of trains were to be worked into the timetable, there could be one train every two hours on the route, if the demand was there.
I certainly believe there could be a timetable, that would meet the objectives of attracting business and leisure passengers away from the roads.
Tourism And Leisure Potential
The Settle and Carlisle Line is known as one of the most scenic railway lines in England, if not the whole of the UK.
There are important tourist sites all along the route between Leeds and Glasgow
- Leeds – The station is well-connected in the City Centre.
- Saltaire – For the World Heritage Site and Salt’s Mill
- Keighley – For the Keighley and Worth Heritage Railway
- Settle – The town of Settle is worth a visit.
- Ribblehead – For the famous Ribblehead Viaduct
- Appleby – For the Horse Fair.
- Carlisle – The station is well-connected in the City Centre.
- Glasgow – Glasgow Central station is well-connected in the City Centre.
Many of the stations are used by walkers and others interested in country pursuits.
I believe that it is a route that needs a quality rail service.
Travel Between London and Towns Along The Settle And Carlisle Line
In Thoughts On Digital Signalling On The East Coast Main Line, I said this.
I think it is highly likely that in the future, there will be at least one train per hour (tph) between London Kings Cross and Leeds, that does the trip in two hours.
It may seem fast compared to today, but I do believe it is possible.
With a timely connection at Leeds station, will this encourage passengers to places along the Settle and Carlisle line to use the train?
What About the Carbon Emissions?
The one problem with using InterCity 125 trains on this route, is that they are diesel-powered, using a pair of Class 43 locomotives.
But then there are over a hundred of these diesel-electric locomotives in service, nearly all of which are now powered by modern MTU diesel engines, which were fitted in the first decade of this century.
Consider.
- The locomotives and the coaches they haul have an iconic status.
- Great Western Railway and Scotrail have recently developed shorter versions of the trains for important routes.
- There are over a hundred of the locomotives in service.
- Companies like ULEMCo are developing technology to create diesel-powered vehicles that can run on diesel or hydrogen.
- There is plenty of space in the back of the locomotives for extra equipment.
- MTU have a very large number of diesel engines in service. It must be in the company’s interest to find an easy way to cut carbon emissions.
- I believe that the modern MTU diesel engines could run on biodiesel to reduce their carbon footprint.
And we shouldn’t forget JCB’s technology, which I wrote about in JCB Finds Cheap Way To Run Digger Using Hydrogen.
If they could develop a 2 MW hydrogen engine, it could be a shoe-in.
I believe that for these and other reasons, a solution will be found to reduce the carbon emissions of these locomotives to acceptable levels.
Conclusion
In this quick look, it appears to me that a Glasgow and Leeds service using InterCity 125 trains could be a very good idea.
