I need information on what components I would have to purchase to upgrade a Lionel 18203 CP SD-40 from the 1990's. It has dual Pullmor motors.
The question is what component or components do I need to purchase to upgrade to TMCC with Cruise. I know Railsounds can be added later. It does appear the ERR AC Commander is needed but does this include cruise or is another component needed ?
I have tried contacting ERR in CA but they put me off to others. Their website is not clear at least to me.
Thanks for any help.
