D-Train Order For Marston Vale Confirmed

The title of this post, is the same as the title of an article in the April 2018 Edition of Modern Railways.

It gives a few more details on the order from West Midlands Trains for three Class 230 trains to provide the service on the Marston Vale Line.

• The trains will be in operation in December 2018
• Two trains will operate the daily service.
• The trains will be diesel-powered.

When the trains come into operation, extra early morning and late-night services will be added from Monday to Saturday.

Battery Prototype

The article also gives more details of the battery prototype.

• The train has four battery rafts, each with a capacity of 106 kWh
• Range is up to fifty miles with a ten minute charge at each end of the journey.
• Range will increase as battery technology improves.
• The train is charged using a patented automatic charging point.
• The batteries will have a seven-year lifespan, backed by a full warranty.
• Battery rafts would appear to be interchangeable with the diesel generators.
• Hydrogen power will be used within the next few years.

The specification seems comprehensive and it would appear there is a high degree of innovative automation and well-thought-out electrical engineering.

Train Energy Consumption

The train has the following characteristics.

• Two cars
• 424 kWh of battery capacity.
• 50 mile range

This gives a consumption 4.24 kWh/per car/per mile.

In an article in the October 2017 Edition of Modern Railways, which is entitled Celling England By The Pound, Ian Walmsley says this in relation to trains running on the Uckfield Branch, which is probably not much more taxing than the Marston Vale Line.

A modern EMU needs between 3 and 5 kWh per vehicle mile for this sort of service.

I am surprised that the Class 230 train lies in the 3-5 kWh range, but then I’m not sure of the weights of the two trains.

I estimate two-car units to weigh as follows.

• Class 230 train plus batteries – Around 50 tonnes.
• Electrostar – Around 90 tonnes
• Aventra – Around 80 tonnes

I shall get some better figures, when I actually see the trains, as the weight is on the side.

The Pop-Up Train

The article talks of the concept of a low-cost pop-up train as a solution for a regional or commuter train.

Export To America?

This pop-up train could be designed to be used to demonstrate rail services in America.

Henry Posner, who is promoting the train in America is quoted as saying cities could use the train to test possible services with passengers on board ‘for less than the cost of a consultant’s study into a possible service’.

These demonstrations will be on freight lines, where for reasons of safety, the passengers trains would run during the day and freight trains at night.

Is America ready for an invasion of remanufactured forty-year-old London Underground D78 Stock trains?
