The MÁV series M41 is a four-axle diesel locomotive developed in 1969 and delivered in 107 copies to MÁV from 1972-1984 , which should replace the last steam locomotives in operation. Machines of this type were also delivered to the Gysev and the OSE .
history
The history of this locomotive goes back to the MÁV series M46 , of which Ganz-MÁVAG handed over two similar locomotives for testing the MÁV in 1969 . The test locomotives had an asymmetrical central driver's cab and a twelve-cylinder four-stroke diesel engine from Ganz , which developed 880 kW (1200 hp) at 1500 rpm. These two copies were not taken over by MÁV.
From this locomotive, Ganz-MÁVAG developed the final type M41 in 1972 , with which the last steam locomotives on non-electrified routes could be replaced, especially the MÁV class 424 . The locomotives with their axle load could be used freely, from freight train service to express train service. The technical data given correspond to the book "Traction vehicles of Austrian railways".
After 2002, the machines were gradually repowered and new engines from MTU and Caterpillar were installed . They will probably be in use until 2017. The locomotives have already been taken out of service at OSE.
technical description
In contrast to the two model locomotives, the locomotive is a machine with two end cabs. A SEMT Pielstick motor , which was built under license by Ganz-Mavag, serves as the drive unit . At 1500 rpm it developed 1325 kW (1800 hp).
It is equipped with a hydraulic transmission from Voith , type L 720 + rU 2. The transmission consists of two torque converters and a mechanical reversing gear .
The train was heated by an alternator connected to the diesel engine. The electrical system of the machine was also controlled via a rectifier.
