I guess that the idea is that at 57th Street-Seventh Avenue when the N, QB or Q trains terminated on the center express tracks, the local EE or RR, R or W trains on outside local tracks were free and clear to enter and exit the station. Such a station like 57th Street-Seventh Avenue, or the Brighton Beach station (basically a similar design) are rather flexible in operation for both the terminating trains and the through local trains. At worst in the case of trouble, trains can be routed around a problem. At least the riders could be let off of the train, or allowed to take the through trains to their destinations. In addition some of the terminating trains could be sent on the through tracks to other destinations until the problem train has been dealt with.In the case of the 57th Street-Sixth Avenue station being a simple two-track station with center platform, the terminating train blocks the movement of the local through train for a period of time. At worst in case of trouble, the through train CAN NOT be routed around the stalled train. In the very worst case scenario the through train might have to "wrong rail" back to a previously served station. Such an operation would foul the train traffic on the railroad, possibly requiring major changes for other trains. In addition, riders could easily be heavily delayed in such an operation. Basically there are fewer options available if something were to occur when the 57th Street-Sixth Avenue station with its two-track center platform setup is used as a terminal and as a through station at the same time. Look at the 59th Street-Lexington Avenue local station for the #6. Railroad north of the station is a center track that ends at a bumper. There an uptown terminating train can discharge passengers at the platform, relay on the center track, and when ready return to service on the downtown local track. While the through-trains are free to continue travel either uptown or downtown. Yes, the station is a 2-track local station with side platforms, but the extra center track provides flexibility when something goes wrong. I that is the major point being made. Mike |
