Why can I download an SD40-2 of all types into TR06 but cannot download into TC? Both CMP’s show basically the same list and if it depends on discrepancies, why in hell are they in TC to begin with. Hell if I wanted to play in with trams I’d go to Frisco. Two bad mistakes I made this year. I built my new system around Vista and got involved with Trainz. Pardon me while I go blow my brains out.
