PUBLICIS www.man-engines.com MAN engines. For powerful trains. It’s an excellent train of thought that leads to a decision in favour of the reliable diesel engines from MAN. With performance ranging from 110 kW (150 hp) to 662 kW (900 hp), extremely economical and environmentally friendly, these really powerful engines are always on track for success. A decision that sets the right signals for the future.

Our final report in this block deals with experience with the RU 800 S track-reconstruction machine, which has been designed to handle several of the work processes involved in the replacement of both ballast and rails. It is able to complete its work with very much shorter periods of track closure, and the newly laid track is of a better quality.
