I have installed several Lionel Command Control Switches on my layout. I have wired them to my GW-180 transformer and the lanterns light up. Have purchases a Legacy CAB-1L hand held to operate the switches, but I believe I need the Lionel Trainmaster for operation which I have ordered. My question is: How do I wire the Trainmaster into my layout? I have MTH engines and have a TIU on order (9 months) so I believe I need to wire to the track and to my GW-180 for now, but am not sure just how. Can/would someone give me a quick explanation of what I have done incorrectly, or what to do correctly. please? Thank you.
