From a previous message:Posted by jabrams on Wed Aug 27 00:12:39 2014, in response to Re: Uh oh..

Isn't there a permanent red/red on the south end of the n/b Jay Street station on the A line, to prevent a train that used the crossover from continuing in the wrong direction towards H/S s/b on the n/b track. Shouldn't there be a similar signal on the north end of s/b Canal Street? I also noticed red signal on the S/B 2/3 at Chambers Street pointing N/B in the center of the station. -------------------------- I am guessing here, but here goes: I suppose that the Jay Street station (A,C,F) as well as the Chambers Street station on the (#2 & #3) are often used as terminals, just like the 34th Street-Sixth Avenue station (B,D,F,M). The usage of those normally "through" stations as terminals probably might have required more attention to the idea of handling trains that would in some sense be on the "wrong tracks". For example there are "GO's" where the #1 terminates on the express track at Chambers Street before traveling uptown. Just a hunch, but think of the 34th Street-Sixth Avenue station, before 1967 and the extension of the express tracks. Trains that terminated on the center express tracks did not have "worry" about uptown trains on the express track. After the new tunnel opened that worry had to be addressed. This is pure speculation on my part, but I'm wondering if the Canal Street station (A,C,E) was never envisioned to be used as a "terminal" under any scenario with reverse of the normal direction of travel movements. The station was designed as a "terminal" for its usual direction movements. For example under what circumstances would trains from Brooklyn travel up past Fulton Street and Chambers Street to terminate and relay at the downtown track at Canal Street? (I very much doubt even a direct layup to/from a Brooklyn train yard to/from WTC.) In other words to put "wrong direction train markers" alongside particular tracks, means that one envisioned the track being used that way, even if not very often. It is a bit difficult to design for or protect against events that one can not even imagine as extremely less than remote possibilities. Mike |
