The HLS car is used by the Hungarian State Railways at winter, to melt the snow off the switches. It achieves this by using gas torches. Since it cannot move on its own, it is pushed by a locomotive.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 decal files are also included in CorelDraw format (send a message for different format). For a running model you will need Peho axle bushings and 7.7 mm wheels.
