Posted by Stephen Bauman on Tue Dec 22 11:12:47 2015, in response to Re: W train returning when Phase I of the 2nd Av subway opens in December 2016?., posted by SelkirkTMO on Sun Dec 20 16:38:30 2015. It will take 8 seconds for the train to accelerate from 10 to 30 mph @ 2.5 mph/sec after clearing the interlocking. It will have traveled 240 feet during that time. It will travel another 360 feet in 8 seconds at 30 mph. The train's rear will now be 600 ft clear of the end of the interlocking and 900 ft clear of the interlocking's entrance. This is sufficient for the interlocking to display a yellow aspect and allow the follower to proceed at 10 mph. Additional time: 16 seconds; total time: 66 seconds; time to next train: 90+ seconds. Margin: 24+ seconds. |
