This video introduces the Roco BR012, a German steam locomotive, in an oil-fired version and with sound. In the video, the BR012 refuels with oil, shunts, picks up a passenger train with the so-called “Umbauwagen” and ends its service via the overhead bridge. This roller bridge was built from a defective printer and equipped with control via an Arduino microcomputer.
