Santa Fe F7 TMCC ABA - Lash-up / Train setup not working - FIXED

Matt,

         I do not have a CAB 2 handy so I may miss something but according to your screen shots your Train number is 32. TMCC/Legacy only allows single digit train numbers so 32 is no good use 1, 2, 3, 4, 5, 6 etc to 9. 

         Also most Lionel AA sets equipped with TMCC or Legacy the rear A unit whether it is powered or non powered is always programmed from the factory as the rear unit. I have PRR Sharks TMCC where both engines are powered and I have them both programmed with the same number 52. The rear engine starts with the back end of the engine going forward so no need to change the direction or in fact to set the lash up as a train. It’s just engine # 52 the same number as the lead A unit. If your B unit is non powered you can set it to the same engine # it really does not matter how it faces in direction. If it is a powered B see which direction it starts and put it in that direction in the lash up. So in my opinion use # 32 as the engine number for each one of your units and run your lash up as a engine not a train.

Matt,

    Forgot to mention the rear A unit will be lit correctly using the single engine number. The headlight will be off going forward in the lash up and on when you go in reverse.

Thank you John, that was it. I totally forget that you couldn't use double digit train number for TMCC. Working fine now, and I will try out the setup you noted above in your first post.
