All my sidings are automatically powered on using a Triac relay that is controlled by the position of the turnout to that siding. That eliminates the need for additional controls and also prevents an engine on the siding from joining the main track if the turnout is in the "wrong" position.
So throwing the turnout to the siding turns power on to the siding as well? That seems like a nifty idea and quite foolproof too. Can you provide any details for the "Triac relay" please?
