OK, but how far up could the inner tracks go in the short distance between the south end of B'way-Laf and the point where the crossover was? The F/M tracks are level in the area (until the M splits from the F), right? And the distance between where the crossover formerly was and the point where the B/D tracks cross over the F tracks is significantly longer than from the south end of B-L station to where the crossover was? So the F/M track could be raised between the station and crossover so it's level was close enough to that of the B/D tracks to allow the crossover, then dropped down again in plenty of time to get back to the level that passes under the B/D tracks. A lot of work, yeah. A question would be how long the track would have to be closed to accomplish it. But I can't see that it could be impossible, it seems like they could have done something like that when Chrystie was originally built.Another possibility would be to add a crossover north of B'way-Laf, even if that is inconsistent with the usual IND practice. I know, adding a crossover where there never was one before presents the problem of replacing the support provided by the pillars that would have to be removed. But that can be done? |
