This isn't very realistic, since a power outage at 36 St, Queens should not affect switches in Brooklyn. Also, how come 4 Av local trains can only run via 6 Av Local, while B and D trains can continue via 6 Av Exp (that's only one inconsistency, there are others)?
Despite that:
Trains run express south of 59 St.

Trains run via 8 Av in both directions between 5 Av/53 St and W 4 St.
Trains run via bridge, 6 Av, and 63 St.

Because of a fire in a control tower, no switches can be moved along the Broadway Line between Queens/Queensboro Plaza and Atlantic Av, inclusive.
