Following on from the initial serial order of 500 MAN engines, the French rail vehicle manufacturer Alstom has ordered another 200 units for installation in its Régiolis, diesel electric railcars.

Four or six MAN engines of model D2676 LE621 will be installed in each vehicle. The serial delivery of the Régiolis rail cars from Alstom to the French rail operator SNCF is scheduled as of April 2014. With a power rating of 338 kW (460 hp), the efficient MAN straight-six cylinder engine impresses with its compact and weight-saving design. This is achieved through the use of a two-stage supercharger with exhaust gas recirculation as well as by choosing to dispense with an SCR (Selective Catalytic Reduction) unit.

Due to the compact installation dimensions and low weight of the vertically-installed D2676 LE621 MAN engine, the complete drive unit package which comprises a diesel engine and generator, cooling unit, air filter and exhaust system and electrical and electronic systems can be arranged on the roof of the vehicle. The improved access eases servicing considerably while, at the same time, the end-to-end low flooring of the interior of the vehicle noticeably improves passenger comfort. In this way, Alstom will introduce the first major fleet of end-to-end, low floor section rail cars with a roof-engine concept on to the European market.

Fast pick-up and economy in continuous operation

MAN offers efficient 6- and 12-cylinder diesel engines for use in railcars, tracks and shunting locomotives, railway maintenance vehicles and power supply. They generate power outputs from 257 kW (350 hp) for railcars and 265 kW (360 hp) for locomotives to 735 kW (1,000 hp), while engines for rail power generation are rated between 230 kW and 543 kW (313 hp and 738 hp). MAN engines are compact to install – either conventionally in the drive module or in a space-saving manner under the floor or in the roof. Their clear advantages lie in a fast pick-up and economy in continuous operation – in compliance with the various exhaust-gas standards applying throughout the world.
