Sorry if this is long winded but two questions in one
I am thinking of motorising a gwr slip coach
I would like it to run pulled by the train
Until it nears the station then power from its motor to run (coasting)
Into the platform
If I use geared motor/power train it will not freewheel
So could I belt drive straight from motor to axel
And would the motor then feed power back into the decoder
Like back EMF but all the time its part of the train
