This may have happened already in the 346 pages of this thread, but I didn't find anything in my search, so I'll ask here.
What do people here think would be the best option to resolve the congestion issues at Dekalb? My understanding is that by having the 6 Av routes on the north manh bridge tracks and the Broadway routes on the south, there would be less (or no more at all) crossover/merging issues at Dekalb. I had this idea the other day, but I don't know if it makes sense, so I was hoping to have some holes poked in it: and [run the same in Manhattan in the Bronx]:
runs the same as it does now runs as the does now. The and both take the express track at Dekalb. runs as it does now.
runs as the does now on the Brighton Line.
I don't see there being a huge issue with this, because Broadway and 6 Av have plenty of transfer opportunities and are already pretty close as it is. Would a rider from the Brighton line who works near Bryant Park be super inconvenienced to now have to get off at Times Sq?
People riding from Sea Beach to Astoria or Brighton to the Bronx already had a pretty burdensome commute as is. I think the trade-off of less congestion-related delays makes up for the now-needed transfer.
And, to add capacity, totally unrelated the DeKalb interchange, would it also make sense to run the Astoria to Bay Ridge and terminate the at 9 Av on the West End? I don't see a use in adding West End express service, especially now that a cleared up interchange will make West End service better to begin with.
