Thanks again everyone -- i just bought another MTH engine (EMD F40PH Diesel Locomotive, Massachusetts Bay No. 1000) which makes #4 MTH for me, so i really want to make this work.
@CAPPilot thanks a ton for the illustration
@Myke do you happen to have an illustration similar to Cappilots? I have three mains and an Atlas turntable (i am going to wire each of the whiskers on separate toggles). I already purchased the MTH Z4000 transformer. Is the lastest MTH TIU the MTH O 50-1003? And is the most recent MTH Remote the model 50-1002? I just found one of them on ebay.
Thanks a ton everyone
