Train going from Omaha to Lincoln (and back) on game days, how popular would that be? Have a food cart, bar, Husker videos and tunes going. Starts leaving omaha 5 hours before the game...
Dump off in the Haymarket. The only problem would be the congestion that would cause at the station in downtown Omaha, I'm sure. They'd have to have buses running to and from the station from some large perimeter lot in Omaha.
