Yep, I know about The Electric RR guys, I've bought some of their stuff to convert a couple of engines. They don't know anything about the TAS stuff, or at least they're not admitting it. :)
Don't know if this will help, but I googled and came up with this link: http://www.mylargescale.com/Community/Forums/tabid/56/aff/33/aft/113283/afv/topic/Default.aspx which led to this site: http://www.electricrr.com/
Does anyone have, or have an idea of where to obtain, the documentation for the Train America Studios TMCC conversion package? I have a steamer with this package, and I'd like to get some documentation for it.
