HELJAN HE45521 - Series MO 572 DSB railcar, Ep.III, DC/DCC

The DSB MO series vehicles were diesel railcars that were built in several series for Danske Statsbaner (DSB) by the Danish engineering works Burmeister & Wain (B&W) in Copenhagen and Frichs in Aarhus. In 1935, the MO series was built as a more powerful version of the 1933 by Frichs The MP series was commissioned by DSB. The first two trains were built by B&W, with the car bodies supplied by Scandia A/S in Randers and the electrical equipment by Titan in Odense.

All other trains were built by Frichs and Scandia.
The simultaneous development of the MS Lyntog express multiple units led B&W, as Denmark's largest mechanical engineering company, to demand a share in the engine deliveries. Due to certain political pressure, DSB accepted the motorization of two MO railcars by B&W. The car bodies and bogies for the two vehicles were built by Scandia, while B&W supplied the engines and Thrige supplied the electrical equipment.
Compared to the MP series, a more powerful engine type was developed and these traction motors were also used in the Lyntog express railcars. The main innovations were an ASEA-Åkerman remote control system for double traction and the now two-axle bogie with the two electric traction motors. The railcars had a luggage compartment, a toilet and a driver's cab at each end.
