The first wagons of the Dunakeszi family were created in the 40s, and were the backbone of the passenger trains of the Hungarian State Railways during the socialist era. The Bah, Bhv, BDt, BDh wagons were/are used in regional service, while Ap, Bak, By and WR225 wagons were/are used in long distance trains. The model is a TT scale (1:120) replica of the original. The files are ready-to-print. The carbody, chassis and the interior are to be printed with an FDM printer, and the smaller parts are to be made with a DLP/SLA printer. Recommended layer height are 100 and 25 microns respectively. The decal files are also included in CorelDraw format (send a message for different format). For a running model you will need Peho axle bushings, 7.7 mm wheels, Peho-101 coupler socket and a coupler of your choosing (e.g. Tillig)
