Mine is the (Q6Av) (different to the old one though).
Stations:
Forest Hills 71 Ave [/b]
Roosevelt Ave
Queensbridge
Roosevelt Island
Lex Av
57st
Rockefeller Cntr
W4st
Atlantic Ave
36st
59st
Kings Hwy
Coney Island
Basically it'd be express on the Queens Blvd, Super-express on the 6th Ave Line, express on the 4th Ave Line and Super-Express on the Sea-Beach Line.
The line would use R-68s and R-143s. Not very realistic right (LOL).
"This is a Brooklyn-bound (Q6Av) express train, the next stop is Rockefeller Center. Stand clear of the doors!"
