68 Railway Carriage Uncoupler
Build this mechanism to automatically uncouple carriages from a model
locomotive or another carriage. It can be hidden under a section of the
track and activated by a switch. The design is relatively simple and uses a
servo-based mechanical system that you can make yourself.
