Four to six drive systems, each fitted with a MAN engine, power the Alstom Coradia Régiolos railcar.

Comfort thanks to a compact roof engine

MAN's D2676 LE621 engine provides the ideal prerequisites for the innovative drive technology of the Regiolis from Alstom: thanks to the compact installation dimensions and low weight of the vertical MAN engine, the complete drive package comprising diesel engine and generator, air filter, cooling, exhaust, electrical and electronic systems can be arranged on the roof of the vehicle. The improved access considerably simplifies servicing while at the same time, the end-to-end low floor section realised inside the vehicle noticeably improves passenger comfort.

Extra power for railcars and maintenance vehicles: V12 rail engine D2862 LE63x

The D2862 LE63x was developed especially for rail applications, its base engine is based on the latest V12 engine generation from MAN. Its design is ideal for railcars and maintenance vehicles with outputs from 588 kW to 735 kW (800 HP to 1,000 HP) at 1,800 rpm. MAN specialists from the Rail Business Center support system integration.

With the D2862 LE63x, which is a completely new development, MAN is offering an efficient 12-cylinder engine for rail operation. Additional power over its predecessor is provided by an additional displacement of 24.2 liters. The base engine of the D2862 LE63x has already proven itself in a multitude of applications in agricultural machinery, marine engines, and decentralized energy supply. The compact MAN engine is designed perfectly for underfloor applications making it ideal for installation in railcars (DMU – Diesel Multiple Unit) and maintenance vehicles. Through its perfect interplay with all types of transmissions and generators in this power class, the efficient MAN engine provides ultimate flexibility with regard to integration in the power pack. Furthermore, MAN gives support with its ultimate advisory skills and many years of experience in installation conditions and power design.


Power increase with the same installation space: 6-cylinder rail engine D2876 LUE63x

Compact and flat: MAN is one of the few providers with flat, horizontal engines in its product range. The latest third generation of the D2876 LUE63x generates more power with the same installation space – the ideal foundation for retrofitting railcars.

The flat, horizontal 6-cylinder rail engine from MAN: D2876 LUE63x with 390 kW (530 HP) at 1,800 rpm.

The horizontal D2876 LUE63x is one of the most compact engines in its class. As compared to the predecessor engine, the efficient MAN engine provides an extended range of outputs to 390 kW (530 HP) at 1,800 rpm which it gained from the 12.8 liter displacement. MAN has deliberately made few changes to the engineering design with the further development of the 6-cylinder engine in its third generation.
"With the D2876 LUE63x, we're offering our customers the sophisticated, tried-and-tested technology of our efficient MAN rail engines. At the same time, rail operators get maximum flexibility for retrofitting. Benefits range from the identical interfaces in the power pack right up to spare parts the customers already have in stock and can still use", said Reiner Rößner, Head of Sales at MAN Engines.
