The 442 class locomotives were used mainly in the regional passenger service around Budapest from the 20s until the 70s. It was the most powerful tank engine of the Hungarian State Railways. The model is a TT scale (1:120) replica of the original. The package contains every variant of the locomotive ever existed. The files are ready-to-print with resin DLP/SLA printers, recommended layer height: 25 microns. The plates can be made from photo-etched brass, for which the film is included in pdf format. The building manual is also included in Hungarian (message me for English translation). For a running model you will need a Tillig or BTTB BR86 chassis.
