Pictures of MÁV Class 442 steamer

The MAV Class 442 2-8-2T steam engine was developed as a larger version of the Class 342 locomotive. The Class 342 engines as motive power for commuter trains around Budapest had serious difficulties on the hills od the Gödöllö line. The Class 442 was aimed to this place mainly. It inherited many details from the Class 342, but it had four driving wheelsets instead of only three of its predecessors. The boiler was constructed as Brotan boiler, as all steamer boilers in Hungary during WW1, but it was considerably larger than those of the Class 342. Perhaps the designers learned from the problems of the Class 342, where the shallow boiler's limited steam reservoir capacity made many troubles for its firemen.

The Class 442 was mainly in service on the Budapest - Gödöllö line, with some trains up to Hatvan. This remained so after the mid. '30s, when the nastiest incline was removed by building a deep cut through the highest section. They remained there until the late '50s, the electrification of this line. After this they were put in service around in Hungary, where there was a need for a heavy commuter engine. The only surviving member of this Class, the 442,013 is put on plinth on the station of Hatvan.
