Thanks to Tomek for first schienenbus.
I scaled his design to fit with TT gauge rail. I added stairs, bars, boogie (not original, is from a romanian railbus)), motorization adjustable pieces, supports for micro LEDs.
All the pieces was designed to be detachable for service your model locomotive.
This design is not intended for comercial use. Only for 3D printers fans.
I do not add:
The author remixed this model. Imported from Thingiverse.
