I want to thank everyone for their input, this seems like a great discussion board.

Looks like I need to measure the reverse board that comes standard inside the engine to see if the replacement TMCC board will fit in the same space. I would like to add rail sounds, which means running a tether and locating the speaker inside the tender.

Thanks for all your help

Greetings.

Is it possible to upgrade the Semi-Scale O-27 Hudson N 4-6-4 with Lionel TMCC? I'm looking for a semiscale Hudson that I can operate with my other command control engines, and this one would be great.

Thanks.
