Re: Some guy is suggesting the closure of 3rd Ave on the L line

Posted by Stephen Bauman on Wed Oct 7 21:12:36 2026, in response to Re: Some guy is suggesting the closure of 3rd Ave on the L line, posted by AlM on Wed Oct 7 18:44:40 2026.

There are now 18 trains arriving at 8th between 7:37 AM and 8:35. There used to be a max of 15 in an hour.

Today, they had 21 scheduled to arrive at 8th Ave between 8:12 and 9:12

Here's the schedule that can be pasted into a spreadsheet

There were 24 tph arriving at 8th Ave at one time, without keying by. CBTC braking headways are 8 seconds longer than a properly designed fixed block system. That's part of the problem. A second problem is the direction reversing time at 8th Ave. A third is the software they use to make up the schedules.
