Abstract
A model train coupler which can be opened using a remote signal. The coupler design includes an upper arm and a lower arm, both of which pivot around a common axis. The two arms are mounted in a coupler box which is attached to a piece of rolling stock. One of the arms includes a knuckle located outside the coupler box. The other arm includes a latch positioned to open and close against the knuckle. A linear actuator links the two arms together. When an electrical current is applied to the linear actuator, the latch is rotated away from the knuckle, thereby opening the coupler.
