The Bbmot was a diesel-mechanical railcar of the Hungarian State Railways, manufactured by Ganz. They were operated between the 50s and the 80s.The model is a TT scale (1:120) replica of the original. The files are ready-to-print with resin DLP/SLA printers, recommended layer height: 25 microns. The chassis are to be made with an FDM printer. The decal files are included in CorelDraw format (send a message for different format), also the drawing for the windows (can be made with cnc milling from PMMA or PC). For a running model you will need Peho axle bushings, 7.7 mm wheels, a coupler of your choosing (e.g. Tillig) and a suitable drive. The drive can be made from the bogie of a BTTB M61, and a small motor. However a conversion of an MTB ABbmot is recommended as it's a more reliable drive.
