So, my new question is... what is your ultimate session of 1830+?
Almost certainly classic 1830. It may be closely followed by a game that adds the Pere Marquette and little else.
The idea of being able to use a 75 or 76...
I believe you mean #5 and #6.
FWLIW I am particularly unhappy with the non-57 yellow city tiles. The C&O is already arguably the strongest company in the game. It doesn't need help. Ditto the effects on the NNH&H/B&M pair, or NYNH&H/NYC pair.
