Reverse moves should not preclude routing, if proper precautions are taken. (Such precautions are not possible in this case.)

Two examples of reverse moves from the past are: the Rockaway Round Robin Shuttle - Euclid to Rockaway Park to Far Rockaway; and the BMT Queensboro Service - Main St to Queensborough Plaza to Astoria.

Here are three examples of special routing as a result of track work.

Before the present crossover was installed between 33rd St and Queensboro Plaza and before it was acceptable to truncate the 7 to operating between Main St and Queensboro Plaza, the procedure was for single track operation between 33rd St and Hunters Pt Blv. 7 trains left 33rd St on the local track then then reverse moved back onto the express track and then reverse moved onto the Queens bound track. This was two reversals between 33rd St and Queensboro Plaza. Two T/O's were used. The TA built a crossover, at considerable expense but now truncates the line, removing the incentive for the considerable expense that was incurred.

When the Clark St tunnel was closed, 2/3 expresses would switch to the local at Chambers and go around the South Ferry loop to Bowling Green. They would switch directions and proceed to Brooklyn via the Joralemon St tunnel. A similar strategy was employed, when the Joralemon St tunnel was closed.

When the Manhattan Bridge was closed (before the big closure) D trains would proceed from Bway-Lafayette to Essex St, then relay beyond the station and proceed via Nassau St and the Montague St tunnel into Brooklyn.

A current example of a reverse move is the late night and weekend PATH service: 33rd St to Hoboken to Journal Sq.

In most of these cases, the reversal occurs within a station. Both G train reversals must occur as a the result of a relay, outside a station. This presents a problem because either an additional T/O is required or T/O's must overcome their phobia of confronting passengers. This phobia is what led to the current fumigation policy.
