If you like passenger trains, you could always do PC with their PRR, NYC, and NH mismatched trains. Even early Conrail would be neat to do with Amtrak's early trains. They were still running the Broadway and other names trains. With the mix and match cars and engines, they were really quite wierd looking at times. Remember a Florida southbound train at Alexandria, VA the first couple months of Amtrak with a Burlington E unit (one of the earlier E's) on front with 2 other E's (ACL) and at least cars from 6 different RR's in the consist.
