Depends on how bad the switch is...
Norwood to 2nd Avenue, 36th Street to Coney Island
Astoria to Whitehall, 36 Street to Coney Island
Forest Hills to Prospect Park, 59th Street to Bay Ridge
Shuttle Buses operate as follows:
Jay Street-Metrotech to 36th Street via Jay Street, Livingston Street, Flatbush Avenue, 4th Avenue.
(Before I get shot down, I extended the to Prospect so people can get a transfer to the at Jay St for service, and there could still be somewhat of a transfer from Atlantic Avenue to the , then the and .)
Why would that matter...
