I've done several searches for this information, and really haven't found anything definitive. I have the TMCC versions of Lionel's Culvert Loader and Culvert Unloader accessories. I think they're absolutely great. I think I saw a coal loading station, but the discussion said it was an early TMCC product and there was a remote control switch connected to it. At least that's my recollection.
Are there other TMCC/Legacy accessories out there that can be completely controlled by a Base1-L/Cab1-L system?
