Subway FAQ: Places Where There Aren't Track Connections

From looking at the subway system route map there appear to be a number of connections that might be useful for current or future subway routings. Here are some that appear to exist but DON'T.

1. There is no connection between the J and E lines of the Archer Avenue Subway. The Archer Avenue Subway consists of two tracks on each of two separate levels, and there is no interconnection between levels.
2. There is no connection between the A and G lines at Hoyt/Schermerhorn, e.g. for allowing a southbound G train to use the Cranberry Street tunnel to Manhattan/8th Avenue.
3. The connection of the 8th Ave. and 6th Ave. IND lines via 53rd Street do not permit all logical routes, e.g. a train heading uptown on 8th Ave., cannot turn and head downtown via 6th Ave., and a train heading downtown on 8th Ave. cannot head "uptown" to Queens.
