Rolls-Royce Commences Series Production Of Hybrid-Ready MTU PowerPacks For Irish Rail

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

This is the introductory paragraph.

Rolls-Royce is to supply its very first series production MTU PowerPacks which are prepared for future use as hybrid traction units: Iarnród Éireann Irish Rail, the national railway operator of the Republic of Ireland, has ordered 41 of these MTU Hybrid-ready PowerPacks. Fitted with MTU 6H 1800 R86 engines, the PowerPacks comply with the EU Stage V emissions directives and each delivers 375 kW from the diesel engine as well as 150 kW from the electrical machine.

Later the aim would be to add batteries to the PowerPacks to make the trains fully hybrid.

I do think Rolls-Royce MTU might have a game-changer here.

  • You take a modern fleet of diesel multiple units like a British Class 170 trains or an Irish Class 22000 trains,
  • For starters you replace the old diesel engine, with a modern one that meets all the latest environmental regulations.
  • It surely helps both sales and engineering, when the old diesel engine was supplied by MTU.
  • Later you fit appropriately sized batteries to the PowerPack to create full hybrids with regenerative braking.

In Iarnród Éireann Orders Stage V MTU PowerPacks, I said this about fuel consumption and emissions.

The aim is to achieve a reduction of over thirty percent in both fuel consumption and carbon dioxide emissions.

I would suspect that with savings like that, the case for conversion might be an easy sell.

Iarnród Éireann Orders Stage V MTU PowerPacks

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

The IE 22000 Class trains appear to be the main rolling stock of Irish Rail.

The Railway Gazette International article describes in detail how MTU are updating the standard diesel engines in these trains with their latest Hybrid PowerPacks.

The aim is to achieve a reduction of over thirty percent in both fuel consumption and carbon dioxide emissions.

From reading the article, it doesn’t appear to be a challenging project, once the testing is complete.

It does appear that MTU seem to get these conversion projects right.

Progress On The Porterbrook HybridFLEX Project

There is another engine conversion project, that uses MTU PowerPacks, underway in the UK, which I wrote about in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks, in September 2018.

Porterbrook call it the HybridFLEX project. I wonder how it is getting on.

This article on Diesel and Gas Turbine Worldwide, which is entitled Ricardo Leading Hybrid Train Project In UK, is the last reference I can find in January 2019.

As there are over two hundred trains, that can be converted in the UK, I’m looking forward to the rolling out of Porterbrook’s HybridFLEX project.

I suspect operators are too, as they’d like to save all that diesel.

Irish Rail And Porterbrook Order MTU Hybrid PowerPacks

The title of this post is the same as that of this this article on the International Rail Jotnal..

This is the first paragraph.

Irish Rail (IE) and British rolling stock leasing company Porterbrook have signed contracts with Rolls-Royce for the supply of 13 MTU Hybrid PowerPacks, the first firm orders for the hybrid rail drives.

Other points are made in the article.

  • IE has ordered nine PowerPacks for Class 22000 trains. If the technology works they intend to convert all 63 trainsets, which will need 234 PowerPacks, as each car has a diesel engine.
  • Porterbrook has ordered four for Class 168 and Class 170 trains.
  • The PowerPacks will be delivered between mid-2020 and 2021.
  • The MTU engines are built to EU Stage 5 emission regulations.
  • The PowerPacks can switch to battery power in stations and sensitive areas.
  • Under battery power, noise is reduced by 75 % and CO2 emissions by up to 25 %
  • Operating costs are significantly reduced.
  • The PowerPacks have regenerative braking, thus they reduce brake pad wear.
  • Due to electric power, the trains have been acceleration, which may reduce journey times.

It seems that passengers, train operating companies, train leasing companies and those that live by the railway are all winners.

If the concept works reliably and meets its objectives, I can see MTU selling a lot of Hybrid PowerPacks.

Which Operators Will Be Used For Trials?

This is a valid question to ask and I’ll put my thoughts together.

Irish Rail Class 22000 Train

These trains only run in Ireland with one operator;Irish Rail, so they will be used for trials.

As each car has one MTU diesel engine and Irish rail are stated in Wikipedia as wanting to run three-car and six-car sets, could they be converting one train of each length?

British Rail Class 168 Train

All the nineteen Class 168 trains of various lengths are in Chiltern Railway’s fleet, they will be the trial operator.

Chiltern also have nine two-car trains, which could be ideal for trial purposes as they will need two Hybrid PowerPacks.

British Rail Class 170 Train

Porterbrook own upwards of thirty two-Car Class 170 trains with CrossCountry, Greater Anglia and West Midlands Trains.

As Greater Anglia and West Midlands Trains are replacing their Class 170 trains, this means that CrossCountry will soon be the only user of two-car units.

The four two-car trains from Greater Anglia, will be going to Trains for Wales (TfW).

TfW currently has thirty two-car Pacers in its fleet, which must be replaced by the end of 2019.

TfW is bringing in the following trains.

  • Nine four-car Class 769 trains from Porterbrook.
  • Eight three-car Class 17 trains from Greater Anglia
  • Four two-car Class 17 trains from Greater Anglia

This is a total of sixty-eight cars.

So TfW are replacing a load of scrapyard specials with quality, more powerful trains, with approximately 13 % more capacity.

TfW are proposing to use the Class 170 trains on the following routes.

  • Heart of Wales line (from 2022)
  • Regional services between South and West Wales
  • South Wales metro lines – Ebbw Vale/Maesteg (until 2022)
  • Crewe-Shrewsbury local services (from 2022)

There is a mixture of routes here and it would be a good trial,

Other Trains

If the MTU PowerPack proves successful and leads to widespread conversion of the Class 168 and Class 170 fleets, will we see the twenty Class 171 trains and thirty-nine Class 172 trains converted to hybrid power?

Conclusion

It looks like a good solid project to me!
