Railway Carriage Uncoupler - July 2023 - Silicon Chip Online
This mechanism automatically uncouples carriages from a locomotive or other carriages, adding realism to a model railway layout. It’s hidden under a section of track and activated by a switch after the locomotive is driven into position. It’s actuated by a servo motor with simple control electronics and a relatively straightforward mechanical system that you can make. by Les Kerr
