My shorty dump car, pulled by Snoopy and Woodstock,
dumps a load of craft store bells for Christmas.
The flywheel circuit in the trailing ore car makes it a little difficult to stop the dumpcar precisely over the electromagnet of the uncoupling track, but you can dump the load or open a coupler while the handcar is in motion, or practice stopping.

A typical Lionel whistle control board is used to activate the remote uncoupling track by way of a transformer mounted whistle/sound button, so no extra wiring is necessary. Depending on the circuit within your transformer for blowing the whistle, the capacitor, 2200 mfd 50V, may not be necessary across the 12V relay's coil.

The circuit will be contained in a small project box that sits next to the track, or under the layout.

The circuit is track-powered.
