New Diesel Locomotive

Freightliner have ordered 30 new locomotives from GE in the USA.

Freightliner order 30 General Electric Genesis JS37ACi locomotives

Freightliner Group has placed an order for 30 freight locomotives of a new design giving greater hauling capacity and a significant improvement in fuel economy than currently seen on the UK network. Project Genesis, which is being developed in partnership with General Electric (GE), will bring new technology to the UK rail freight market, enabling Freightliner to move longer and heavier trains whilst reducing CO2 emissions per tonne moved.

Starting in mid 2009, Freightliner will utilise the most advanced locomotive product in the industry while GE - Transportation will enter the UK rail freight market for the first time. The innovative design offers an array of new features, including AC traction technology and dynamic braking. GE - Transportation’s JS37ACi locomotives allow Freightliner to increase its hauling capacity while lowering fuel consumption by an estimated 10 percent compared to the current locos in its fleet.

This substantial investment, the largest loco order ever placed by Freightliner, fits well with the DfT’s recently published strategy document ‘Towards a sustainable future’ which sets out the transport system's role in supporting continued economic growth and making a key contribution to the Government aim of a 60% CO2 emissions reduction by 2050, The new locomotives enable both economic growth and lower emissions.

The driving cabs of the new loco will bring new standards of comfort to drivers, with air-conditioning as standard. Freightliner have kept the Trade Unions involved (including RMT and ASLEF) and will involve groups of drivers for input into the design and build of the cab.

Eddie Fitzsimons, Chief Executive, Freightliner Group Ltd said; “We are extremely excited about Project Genesis. Not only will we improve our carbon footprint but will be able to move more payload per train than ever before. We have been in discussions with GE over recent months to develop what will be the epitome of 21st century locos on the UK network, bringing revolutionary technology the to rail freight market.”

Robert Parisi, General Manager of International Locomotives and Modernizations, GE - Transportation said; “We are pleased to enter the UK market for the first time and introduce our advanced locomotive product. It’s exciting to provide solutions to our customer’s needs.”

Tim Shakerley, Engineering Director, Freightliner Group Ltd added; “We recognise that a locomotive is a 30 year asset and therefore development of new technology is important to ensure the locomotive is up to date and relevant for its design life. Packaging this technology into a locomotive compliant to the UK clearance gauge and axle weight is a tremendous challenge but we are confident that GE can achieve this.”

Traction
The traction motors are individually controlled via separate inverters. Consequently this leads to better power distribution based on available adhesion and the use of the AC motor with its better torque-speed curve means the loco has a much higher starting torque which means it has a greater starting tractive effort.

Dynamic Brakes
The locomotive is fitted with rheostatic (dynamic) brake. When slowing it uses the traction motors to regenerate energy and put electric current back into the locomotive, using the electric current to drive the auxiliary motors. This is the first time it has ever been applied in a diesel loco in the UK.

Cabs
Dual cabs with left of centre operator desk, and air conditioning as standard. The engine is resiliently mounted to reduce vibration. Cabs are sound insulated and driver information is provided by MMI screens.

Fuel efficiencies
The locomotive is 7% more fuel-efficient than previous locomotives achieving 197g/kwh. By using the energy dissipated by the dynamic brakes to drive the auxiliaries, and controlling the auxiliaries separate from the engine speed, a further 3 % efficiency is gained. It is therefore 10% more efficient than previous locos.

Diagnostics
The locomotive will be fitted with remote dial up software which allows GE to monitor the performance, troubleshoot and find problems before anyone knows they are happening, and dispatch a technician with the correct parts to the location where the loco is going to finish its journey for preventative maintenance.

This is interesting news. Will they at least look different to the 66's? Please God let them look different to the 66's! Variety is the spice of life!!!!

[locojoe]

The engines look very eco friendly, and any diesel loco that reduces CO2 emissions sounds good to me.

[andersley]

Yes, they will look very different from a 66. They will be significantly more powerful and being GE, they will probably sound like a real locomotive.

I was browsing the Dapol Model Railways website yesterday and there was a little bit of text in the news section saying that they will produce models of these new locos and that they will be class 68s.

I should think these new locos would look different to a 66 (I hope) as they are supposed to have a narrow body with an external walkway.

There are some details of this loco in The Railway Herald 111.

[Trev]

Are these locos to be used for a specific type of train? Just as the Class 67's were supposedly primarily for postal traffic, is there a definite need for a new design? I'm not complaining, anything to relieve the monotony (or how about a new word; "mono loco lly") that we've had imposed upon us by EWS.

Similar to the class 58 then.

Auch you never know maybe just maybe EWS will think about a new type to replace the 37s (Ok I am dreaming again)

Narrow Body with exterior walkway

In that case the loco will probably look like two small "sheds" connected by a bridge
I can't imagine anything very stylish. It will just be a case of squashing all the equipment into a suitably sized box.
A bit like this ugly Vossloh creation.

Or the GE version of a 58.
