Cummins And Leclanché S.A. To Collaborate On Lower-Emissions Solutions For Use In Marine And Rail Applications
The title of this post, is the same as that of this press release from Cummins.
This is the introductory paragraph.
Today, global power and technology leader, Cummins Inc., and leading provider of energy storage solutions, Leclanché S.A, announced the signing of a Memorandum of Understanding (MOU). The collaboration represents a significant step forward in providing customers with a broader portfolio of integrated power solutions.
Effectively, this means that all customer requirements for integrated power solutions can be met by the two companies.
It appears to me, that if someone wanted Cummins to provide a system like the HybridFLEX train, I wrote about in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks, then Cummins and Leclanché have the technology between them to create a system.
In the UK, Cummins power these relatively-modern trains.
- Class 175 – 9 x two-car and 15 x three-car.
- Class 180 – 1 x four-car and 12 x five-car.
- Class 185 – 51 x three-car.
- Class 220 – 34 x four-car.
- Class 221 – 24 x four-car and 18 x five-car.
- Class 222 – 23 x five-car and 4 x seven-car.
Note.
- They are capable of 100 mph or 125 mph.
- Condition of the interiors is generally good.
- There are 9 x two-car, 66 x three-car, 59 x four-car, 53 five-car and 4 x seven-car.
- In Grand Central DMU To Be Used For Dual-Fuel Trial, I described innovative fuel trails in a Class 180 train.
- There could be other similar trains in Europe and around the world.
How many of these trains could be converted to hybrid operation, if Cummins and Leclanché were to create their version of the mtu Hybrid PowerPack?
Conclusion
Have Cummins and Leclanché decided that if a hybrid approach is good enough for Rolls-Royce mtu, then it’s good enough for them?
Skegness Station To Benefit From A £3.3m Improvement Package
The title of this post, is the same as that of this article on Rail Technology Magazine.
I took these pictures of Skegness station, on a visit to the town in July last year, which I wrote about in A Trip To Skegness.
I feel that Skegness station would welcome some improvement.
The Rail Technology Magazine article says this about the project.
Upon completion of the project, customers will be able to utilise a number of enhanced facilities, including an improved accessible toilet with changing spaces, two new start-up offices, a community café and retail provisions. Upgrades will continue through improved access into the station for pedestrians and vehicles, offering integration with the surrounding community.
Work is hoped to start this year.
A Modern Zero-Carbon Train Service
If £3.3 million is going to be spent on Skegness station, would it not be a good idea to have better trains serving the station.
In A Trip To Skegness, I talked about updating the hourly Nottingham and Skegness service using Class 170 trains with Rolls-Royce MTU Hybrid PowerPacks.
I wonder if this route could be improved by fitting the Class 170 trains with Rolls-Royce MTU Hybrid PowerPacks?
- The hybrid technology would have a lower fuel consumption and allow electric operation in stations.
- The prototype hybrid is already working on Chiltern Railways in a Class 168 train.
- The Class 168 train is an earlier version of the Class 170 train and they are members of the Turbostar family.
- Rolls-Royce are developing versions of these hybrid transmissions, that will work with sustainable fuels.
- As we have a total of 207 Turbostar trainsets, these could be a convenient way of cutting carbon emissions on long rural lines.
- As Rolls-Royce MTU are also developing the technology, so their diesel engines can run on hydrogen, it is not outrageous to believe that they could be on a route to complete decarbonisation of this type of train.
I believe that we could see hydrogen-hybrid Class 170 trains, with a Rolls-Royce badge on the side.
But would it be possible to go the whole way using one of Stadler’s battery-electric trains?
Consider the service between Nottingham and Skegness.
- It is hourly.
- The route is run by 100 mph Class 170 trains.
- Nottingham and Grantham are 22.7 miles apart.
- Grantham and Skegness are 58.2 miles apart.
- Trains take four minutes to reverse at Grantham.
- Trains wait 20 minutes before returning at the two end stations.
- Trains reverse at Nottingham in a bay platform, which is numbered 2.
- Grantham is electrified.
- Nottingham station will be electrified in the next few years.
- Skegness station is next to the bus station in the middle of the town, so hopefully the electricity supply is robust enough to charge buses and trains.
Stadler make a train called an Akku.
- It is a member of the FLIRT family.
- It is a 100 mph train.
- I wrote Stadler FLIRT Akku Battery Train Demonstrates 185km Range, which means it could run between Nottingham and Skegness without intermediate charging.
This leads me to the conclusion that with charging systems at Nottingham and Skegness and taking a four-minute top-up at Grantham if needed, a FLIRT Akku could handle this route with ease.
Conclusion
Skegness is a town that needs leveling-up. A refurbished station and 100 mph electric trains to Grantham and London would be a good start.
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.
A Trip To Skegness
Last Thursday, I took a trip to Skegness to get out of the heat.
I took these pictures on the way.
These are my observations and thoughts.
Changing At Grantham
A few minutes after getting off the LNER Azuma, the East Midlands Railway Class 156 train arrived at the opposite face of the wide platform.
Unlike some changes you get on trains in the UK, it was all rather painless and unhurried.
The change coming home was a bit slower, but there is a bar on the London platform, that serves a good selection of good beers.
Grantham To Skegness
The journey to Skegness took around an hour and a half and I arrived at 13:51.
Skegness Station
Skegness station is not the grandest, but it does have six platforms, which is probably a lot for just an hourly service from Nottingham and Grantham.
Skegness
I didn’t stay long, as it was surprisingly too cold and I hadn’t brought a coat.
Skegness To Grantham
The return trip was better, as the train was a more modern Class 170 train.
Surely, when East Midland Railways get their full quota of Class 170 trains, then the Poacher Line between Nottingham and Skegness will be one of the routes, where they will be used.
I also suspect that with 100 mph trains always running the service, as opposed to the Class 156 trains, which are only 75 mph units, there could be speed improvements on the line.
- Grantham and Skegness is 58 miles.
- There are a large number of level crossings.
An hour service between Grantham and Skegness could be possible and might generate more passengers.
Rolls-Royce MTU Hybrid PowerPacks
I wonder if this route could be improved by fitting the Class 170 trains with Rolls-Royce MTU Hybrid PowerPacks?
- The hybrid technology would have a lower fuel consumption and allow electric operation in stations.
- The prototype hybrid is already working on Chiltern Railways in a Class 168 train.
- The Class 168 train is an earlier version of the Class 170 train and they are members of the Turbostar family.
- Rolls-Royce are developing versions of these hybrid transmissions, that will work with sustainable fuels.
- As we have a total of 207 Turbostar trainsets, these could be a convenient way of cutting carbon emissions on long rural lines.
- As Rolls-Royce MTU are also developing the technology, so their diesel engines can run on hydrogen, it is not outrageous to believe that they could be on a route to complete decarbonisation of this type of train.
I believe that we could see hydrogen-hybrid Class 170 trains, with a Rolls-Royce badge on the side.
The Massive Greenhouse
I found that this was owned by Fountain Plants.
Is Lincolnshire going to grow the UK’s greens? Or at least give them a good start in life?
More greenhouses like this will enable the UK to create our carbon dioxide and eat it!
Cutting Emissions – Cleaner, Greener Turbostars
The title of this post, is the same as that of this article on Rail Engineer.
It is a detailed technical description about how one of Chiltern Trains’s Class 168 trains has been converted to hybrid power.
This extract from the article gives the results of the conversion.
In July 2021, to celebrate Chiltern Railways’ 25th anniversary, the prototype was used to carry a number of invited guests to Bicester for a celebration lunch. The unit achieved speeds of up to 100mph during this demonstration run and operated with emission free battery power into/out of Marylebone and Bicester. The converted train is expected to reduce CO2 by up to 25%, nitrous oxide by up to 70%, particulates by up to 90% and fuel consumption by up to 25%. There was also an expectation that engine noise level will be reduced by 75%.
The article finishes by discussing how all 450 cars of the combined Class 168/170 fleet could be converted.
The article also hopes that the new Chiltern contract could lead to a full conversion of the fleet to hybrid operation.
It is an article well-worth a read.
TransPennine Express Explores Further Fleet And Capacity Expansion Options
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
First TransPennine Express is hopeful that it will be able to issue a call for expressions of interest in the provision of additional bi-mode trains before the end of March. This follows ‘a healthy level of interest’ in its existing call for expressions of interest in the supply of bi-mode locomotives to replace the Class 68s which work with its MkVa coaches.
I wrote about the expressions of interest to replace the Class 68 locomotives with new bi-mode locomotives in Suppliers Sought For New Bi-Mode Locomotives For TransPennine Express And Great Western Railway.
This was my conclusion in the related post.
When I saw First Group’s proposals, I thought that they were over ambitious.
But after doing a few simple calculations, I think they can decarbonise some, but not all of the TransPennine Express services and the Night Riviera.
So do First Group want to complete the decarbonisation of TransPennine Express services?
These are my thoughts.
The Train Fleet Specification
The Railway Gazette article makes these points about the new bi-mode trains.
- The trains could be existing or new bi-modes.
- It would be desirable for the trains to have a long-term electric-only option.
- Options for this would include removing the diesel engines or converting the trains to battery-electric operation.
- Hydrogen is not mentioned.
- A fleet size of twenty-five trains is mentioned.
- The possibility of electric-only trains in the future is mentioned..
- Five-cars, with the ability to lengthen to six- or seven-cars.
- 200 km/h operation.
There is nothing unusual in the specification.
Will They Be Existing Or New Trains?
I doubt that there are any existing 200 km/h bi-modes in the UK, that are not wanted by their current operators.
I am very certain they will be new trains.
Could The Trains Be Hitachi Class 802 Trains?
The trains sound very much like Hitachi Class 802 trains, that are in service with TransPennine Express, Great Western Railway and Hull Trains, all of whom are First Group companies.
- Long-term, the diesel engines can be removed or replaced with batteries.
- The battery option is under development and should be on test this year.
- The trains can be lengthened to as long as twelve cars, so six- and seven-car trains would be possible.
Hitachi will obviously show interest in this possible order.
Will These Trains Replace the Class 185 Trains?
Consider.
- TransPennine Express have 51 three-car Class 185 trains.
- This is a total of 153 cars.
- On some routes they work singly and on others they work in pairs.
- A three-car Class 185 train has 167 Standard Class and 15 First Class seats or 60.7 seats per car.
- A pair of Class 185 trains have 334 Standard Class and 30 First Class seats.
- A five-car TransPennine Express Class 802 train has 318 Standard Class and 24 First Class seats or 68.4 seats per car.
- It would appear that a Class 802 train is not that far short of the capacity of a pair of Class 185 trains.
- Some of the TransPennine services are very crowded.
I suspect that twenty-five five-car trains be able to handle the the workload of the Class 185 trains.
If a small amount of extra capacity were needed, some of the new trains could be six-cars.
In this section, I have assumed the new trains will be Class 802 trains, but any train manufacturer pitching for this order would adjust the capacity to the needs of TransPennine Express.
The Railway Gazette article says this.
TPE continues to explore opportunities for new services in the north of England, and the move could also feed into government plans for the removal of older and more costly to operate diesel trains elsewhere on the network, should any rolling stock become surplus to requirements at TPE.
So where could the Class 185 trains be used in the future?
Recently, MTU Hybrid PowerPacks have replaced the transmission on a Class 168 train, which reduces carbon emissions and fuel consumption and makes the train quieter and more passenger-friendly, as it doesn’t use diesel in stations.
The Class 185 trains are only fifteen years old and I suspect that MTU have designed the Hybrid PowerPack, so that it can replace the Cummins engine in trains like these.
The conversion could be done as a rolling program, so that any future operator would start with diesel and go hybrid a train at a time.
There has been speculation, that the trains may end up on the East West Railway and I wrote about this in East West Railway Company To Start Second Phase Of Rolling Stock Procurement.
But the East West Railway may prefer to use zero-carbon trains on a route, where there is electrification in places on the route.
Alternatively, South Western Railway run 10 two-car Class 158 trains and 30 three-car Class 159 trains between London Waterloo and Exeter.
- South Western Railway is another First Group company.
- The Class 185 trains could provide a capacity increase.
- The Class 185 trains are 100 mph trains, whereas the Class 158/159 trains are only capable of 90 mph.
The London Waterloo and Exeter Route could be electrified in the future and I am pretty sure, that the Class 185 trains with a hybrid transmission could be a good stand-in until this happens.
Other Train Manufacturers
I believe that Hitachi are in pole position for this order, just because they are an established supplier to both TransPennine Express and First Group.
But twenty-five five-car trains would be a very worthwhile order, so I suspect that companies like Alstom, CAF, Siemens, Stadler and Talgo will also express interest.
Conclusion
Buying extra bi-mode trains will take TransPennine Express further along the route to full decarbonisation.
UK’s First 100mph Battery-Diesel Hybrid Train Enters Passenger Service
The title of this post, is the same as that of this article on ITV.
These are the first three paragraphs.
The UK’s first 100mph battery-diesel hybrid train is entering passenger service to cut carbon emissions and boost air quality.
It was developed by adding a powerful battery to a 20-year-old diesel train to reduce fuel consumption and CO2 emissions by 25%, according to owner Porterbrook.
The firm added that the two-carriage train, named HybridFLEX, also provides a 75% decrease in noise and a 70% decrease in nitrogen oxide.
The battery-diesel hybrid transmission is from MTU, who are a Rolls-Royce company and they go further with this press release which is entitled World Premiere: MTU Hybrid PowerPack From Rolls-Royce Enters Passenger Service.
This is the first paragraph.
Rolls-Royce, Porterbrook and Chiltern Railways are making rail history together with a climate-friendly world premiere: A hybrid diesel-battery-electric train that reduces CO2 emissions by up to 25% entered passenger service in the UK today for the first time. The so-called HybridFLEX train is powered by two mtu Hybrid PowerPacks and is operated by Chiltern Railways on the route between London Marylebone and Aylesbury. Together with the leasing company Porterbrook and Chiltern Railways, Rolls-Royce has converted a Class 168 DMU into the HybridFLEX train. The partners are proving that existing rail vehicles can be used in a climate-friendly way without the need to install complex and expensive new infrastructure. It is the world’s first regular passenger operation with mtu Hybrid PowerPacks, of which 13 have already been ordered.
This is significant for the railways of the UK.
The train that has been converted is a Class 168 train, which itself had been converted from a Class 170 train, when it transferred to Chiltern Railways in 2016.
I think this means that all Bombardier Turbostars in Classes 168, 170, 171 and 172 can probably be fitted with MTU Hybrid PowerPacks.
That is the following numbers of trains and cars.
- Class 168 – 28 trains – 86 cars
- Class 170 – 139 trains – 372 cars
- Class 171 – 20 trains – 56 cars
- Class 172 – 39 trains – 93 cars
Note.
- This totals to 226 trains and 607 cars.
- As each car has an engine, this will be an order of 607 PowerPacks, if all trains were to be converted.
This could certainly help to meet the Government’s aim of getting rid of all diesel only trains by 2040.
Can The CAF Civities Be Converted?
There are three Classes of CAF Civity diesel multiple units; 195, 196 and 197, all of which have Rolls-Royce MTU engines.
Could these be converted to hybrid operation by the swapping of the current diesel engines for MTU Hybrid PowerPacks?
I would suspect they could, as the CAF Civity trains might have been designed after MTU disclosed plans of the MTU Hybrid PowerPack to train builders prior to its announcement in September 2018.
Conclusion
MTU Hybrid PowerPacks could go a long way to eliminating diesel-only trains on UK railways. They could even run the diesels on Hydrotreated Vegetable Oil (HVO) to lower their carbon-footprint further.
Quiet, Clean And Fast – MTU Hybrid Drive From Rolls-Royce For Lake Constance Belt Railway
The title of this post, is the same as that of this press release from Rolls-Royce.
It is the earliest press release from the company, about the MTU Hybrid PowerPack that I can find.
It dates from May 2018.
The press release opens with these bullet points.
- Successful simulation of hybrid train operation on Lake Constance Belt Railway
- MTU Hybrid PowerPack reduces emissions, noise levels and operating costs on the existing infrastructure
- Development is part of the Rolls-Royce electrification strategy.
It looks to me, that the press release was produced as marketing material for the launch of the MTU Hybrid PowerPack, which took place in 2018.
These are my thoughts.
Lake Constance Belt Railway
The Lake Constance Belt Railway is introduced like this by Wikipedia.
The Lake Constance Belt Railway (German: Bodenseegürtelbahn) is a continuous, single-track railway from Stahringen to Lindau-Aeschach in the German states of Baden-Württemberg and Bavaria. It runs mainly along the northern shore of Lake Constance (Bodensee).
Note.
It was originally built by three different railway companies in what were then three different countries that are all now states in Germany; Bavaria, Baden and Wurttemberg.
- It is a 74 kilometre or 46 mile line.
- It is a standard gauge railway.
- The line has lots of curves.
- It appears to have about a dozen stations.
The railway also passes through Friedrichshafen, where MTU Friedrichshafen is based.
Note.
- MTU Friedrichshafen factory is indicated by a red arrow.
- The Lake Constance Belt Railway running between the factory and marina.
It’s all very handy for the factory.
Railway Operations
Services on the railway appear to be run using DB Class 611 trains.
- They are two-car tilting, diesel multiple units.
- They have a top speed of 160 kph or 99 mph.
- They have two MTU engines of 540 kW.
- Forty are still in service.
These trains were replaced with similar but more modern DB Class 612 trains.
- These have similar performance, but are fitted with Cummins engines.
- There have also been problems with the tilting mechanism with these trains
Forty of the earlier trains are are still in service on the Lake Constance Belt Railway and other routes.
It would appear that electrification could be the solution for this single track railway, which is only forty-six miles long.
But it appears some of the locals have objected.
Could it be that MTU Friedrichshafen felt they could provide a better solution?
Simulation Of The Route
The press release describes how the route was simulated.
The operation of the current VT 612 railcar was simulated – it had been retrofitted in virtual reality with MTU Hybrid PowerPacks. That such a retrofit is also possible in a real-world environment has also been demonstrated by a feasibility study carried out by the Deutsche Bahn subsidiary, DB Systemtechnik. This is particularly relevant because these are vehicles that travel fast on curving track. Only these trains, which are fitted with “tilt technology“, are able to negotiate the numerous curves encountered on the Lake Constance Belt Railway track at high speed and thus provide a fast service between Basel and Ulm.
It looks to be an interesting solution to maintain a fast service on a difficult route, that has a twisty bit in the middle.
The press release also describes the MTU Hybrid PowerPack to provide an efficient solution.
The MTU Hybrid PowerPack is a high-tech product from Friedrichshafen and the result of collaboration between the local companies Rolls-Royce Power Systems and ZF Friedrichshafen. It combines the following components to produce an intelligent drive system: a modern MTU diesel engine with exhaust gas aftertreatment, which meets current emission regulations in addition to the future EU Stage V that will come into force as of 2021, an innovative ZF automatic transmission, an electric motor that recovers energy in braking mode and also serves as a drive unit, and an advanced battery system to store the recovered brake energy. The Hybrid PowerPack has demonstrated its reliability, for example, in real-life test runs with a length of around 15,000 kilometres.
Certainly, MTU have done their research and where better, than with a local problem?
Rolls-Royce And Flanders Electric Plan To Develop Hybrid Retrofit Solution For Mining Trucks
The title of this post, is the same as that of this Press Release from Rolls-Royce.
This is the first paragraph.
Rolls-Royce and Flanders Electric have agreed to develop a retrofit solution for hybridizing mining trucks with mtu engines, batteries and hybrid control systems, and Flanders drive train solutions. The two companies have signed a Memorandum of Understanding enabling them to offer a scalable retrofit kit for hybridizing mining trucks in a wide range of mining applications.
This looks to be a promising application of a version of MTU Mybrid PowerPack technology, that is being trialled on a Class 168 train on Chiltern Railways.
They are claiming a CO2 reduction of twenty percent.
Distributed Power Supplies Key To Rolls’ Earnings
The title of this post, is the same as that of this article on Diesel and Gas Turbine Worldwide.
Rolls Royce Power Systems is a German company, that is wholly-owned by Rolls-Royce, that makes power units for trains, ships and power standby systems.
- Despite the pandemic they have not been doing badly.
- Orders appear to have grown 19 % in the last year.
- Climate-friendly products are noted in the article as important for the future.
The company has formed a Sustainable Power Solutions business unit to handle this area.
One of their products recently made its debut in the UK and I wrote about it in First Passenger Journey In The UK With mtu Hybrid PowerPack.
All seemed to go well.
It does appear that one part of Rolls-Royce is on the way to recovery.
The Anonymous Widower
