From a previous message: "Good guess, that's the upper limit for capacity on both the arriving express and local tracks. Other factors would probably restrict it further.Prior to Archer Ave, E's ran at 12 TPH and the F ran at 18. " I suppose the major constraint is that the 179th Street terminal must share its local tracks with the current R and V trains at the 71 Avenue-Forest Hills station. Hence whatever trains it can put out has share the express tracks. In another reality, the 179th Street could be the main terminal for the entire Queens Blvd line, with some trains going to Archer Avenue. While I am not suggesting this, for example, R and V trains could use the local tracks out of 179th Street all of the way to the Queens Plaza station, while E and F trains use the express tracks for almost of the entire distance. E trains could run as they do to/from Archer Avenue, with some E trains starting at 179th Street. F trains could run express all of the way from 179th Street to the junction near 36th Street and then use the 63rd Street tunnel. The 71st-Forest Hills station could be used to provide supplemental rush hour trains (for both local and express tracks), or to take some trains out of service. Of course I know that many might oppose such an operation, but it could be done. The 179th Street terminal is capable of such a feat. Mike |
