Alpha Trains to lease hybrids

MTU and Alpha Trains intend to jointly retrofit Alpha Train’s Talent, Desiro and Lint fleets with MTU hybrid drives.
With the aid of state-of-the-art, in-house simulation tools, MTU will be able to determine what would be the optimum drive solution for Alpha Trains in each case for a variety of routes, customers and vehicles. One possible solution is retrofitting with an MTU Hybrid PowerPack and an additional MTU drive system consisting of an electric motor and batteries. As soon as the optimum solution has been identified for Alpha Trains, the next step will be to retrofit a single vehicle, before moving on to retrofit the entire Class 643 fleet.
MTU‘s Hybrid PowerPack is an environmentally-friendly drive system that combines the benefits of both battery and diesel-powered trains. It is made up of an MTU diesel engine combined with an electric machine, which can be used as both a traction motor and a generator, and the MTU EnergyPack battery system, which stores the energy recovered during braking. As a result, local emission free, battery-powered operation, among other things, is possible. In station areas, the drive‘s noise level is reduced by around 75 per cent (20 dB(A)), with fuel consumption and CO2 emissions down by as much as 25 per cent, depending on the vehicle, route and timetable. The operating costs of vehicles equipped with a hybrid drive system are significantly lower, because the pneumatic brakes, for example, are not used as frequently, since energy is recovered during braking. As a result of the increased acceleration and additional power of the electric drive system, it is possible to make up for delays and to schedule rail services with shorter intervals between trains or additional stops.
