This is a single take, non-narrated demonstration of computer controlled carriage siding shunting operations on my N gauge model railway. See https://diode.zone/videos/watch/4a2ec686-3c13-4d3a-88c3-db280735f242 for a fully narrated video explaining what is occurring in this sequence and how the automated coupling and uncoupling works.
