hi ... just joined this forum.     Trying to get back into the hobby.    I bought a milk car and coal dump car ... and a 5 rail track (UCS-6) and 2 button controller.     Hooked everything up and if i turn up the throttle on the transformer, all works just fine.    But I realize that the throttle needs to be turned up to create power to operate these accessories.    So I tried to wire to the 14 volt A and C terminals on the transformer for fixed voltage.   Again, works fine.     But then I realize that with a locomotive, even with the throttle off, a little power seems to be leaking through.     It would seem it would be desirable then to modify the controller track so physically disconnect any connection between the 4 wires and the rails so there is no possibility of interference.    Any idea how this can be done?

hi ... I have a Lionel LW 'trains master' transformer.

hi ... thanks again ... having that wiring diagram you sent helped me wire it correctly!
