What Tom is talking about are the adapters in the center of this picture. They make the transition from Lionel's Molex plugs to wires. The other option is to just cut off the plug.
However, the problem with using a PH135 is it is an 18 VAC only source. Many accessories work better at 14 VAC or even DC.
Within the last month there was a good thread on how to lower the voltage using resisters. Maybe someone will provide a link.
I use a ZWC with three PH135s attached for my accessories. That way I can fine tune it to the accessory. For DC I use computer power supplies.
