Hi Guys,For the longest time it has been a fundamental aspect of subway "math" that the signal system could only handle about 30 trains per hour, even if specfic terminals could not handle that amount of trains. Now there have been exceptions such as the #7 trains handling 33 trains per hour at Times Square in the 1970's by "keying" by the signals. Such a practice is frowned upon these days, if not ruled out due to changes in operating procedures. So let's just stick with the 30 trains per hour formula. It has been an article of faith that the only sections of track that have 30 trains per hour (or close to it) is the Queens Blvd express tracks with the E and F trains. Basically that is a train every two minutes, and along that route the trains are packed "to the gills" with riders. Generally this has meant 15 E trains per hour, and 15 F trains per hour during the rush hours. Having 15 trains per hour means a train every 4 minutes. In the past we have discussed why F train riders at the Brooklyn local stations would not WANT to give up such local service. Having G trains also stopping at some of the Brooklyn F train stations is a benefit at the close in local stations that have the highest ridership. The discussion / debate / battle on that issue has been won. Often there is a debate or proposal about increasing G train service, with the statement that there would be "too many local" trains operating on the local tracks. The proposal writer wonders if there would be many delays and disruptions if G service was increased. It is hoped that 3 F trains per hour would run express between Church Avenue and Bergen Street as a standard practice. I am pretty sure that if there are delays in service that the MTA dispatchers would route some F trains via the express tracks between those two stations - as a usual way to handle delays. Unless the MTA is going to increase G train service closer to or more than 15 trains per hour, I very much doubt that there will ever be "too many trains" for the local tracks. When was the last time in living memory that the G train ran at anything less than or equal to a train at every 4 minutes during the rush hours on a regular basis? Was it not too long ago that there was a movement of opinion to increase G train service to 10 minutes bewteen trains - 6 trains per hour? Is it now down to about 8 minutes of waiting time between G trains during the rush hours? An F express train once every 20 minutes in Brooklyn is really not much of an express. Mike |
