B division cars could relay on the tunnel portal ramp south of Queensboro Plaza. Nigh time maintenance car moves can be performed using the 11th Street cut into the IND at Queens Plaza, assuming that work trains were not in the way. Unfortunately the diamond cross-over on the 11th Street cut was removed in 2004.Over night shuttle operations limited to single track operation with 30 minute intervals, or replaced by buses. A Division equipment car tripping devices are on the right side of the car, while B Division signals have trip arm on the left side. To move trip arms back to their pre-1949 IRT position would be a major requirement if IRT equipment were to serve Astoria. |
