OK, here's a new map. I'll add the stations later. The opaque-ish purple is commuter rail, and the purple with the white stripe is light rail.

Ideally the commuter system would just connect with a light rail system, the only differance being the times at which trains run (commuter rail only runs during commuter hours). I think the best time for commuter trollies to run would be 6-11 and 2-7.
Oh and I added the Crosstown Expressway and the new OK 152 segment west between I 44 and Mustang, which are near finished or finished. I also added where I think a Norman loop is imperitive and where OK 74 needs to be upgraded to freeway north of Memorial Road.
