Who controls the holding lights at 5 Av (E,M)? |

Posted by gbs on Sat Aug 4 21:31:26 2012 This afternoon when I came down the escalator at 5 Av upper (E,M), the leaving signal was red over red (no train had left recently), and I noticed that the tower has a new door and the interlocking machine has been removed (but the air conditioner above the door was running, even though the room was empty). There are also new holding lights suspended on fishing-rod-like poles installed in the wall; the holding lights were off.As the arriving E train climbed the hill towards the station, the leaving signal automatically changed to green over green, without any punching from the t/o. I thought this made sense, since the E is the only service there during the weekend. But then as the train entered the station, the holding lights went on, and we stayed in the station for over two minutes before they went off and we left. If that location is now fully automatic, who controls the holding lights, and why would they turn on when the signal was already green? If we were being held for time, wouldn't a person have to make that decision and manually turn on and then off the lights? When I first saw those new holding lights in use a few months ago, it was during the week, and I assumed that they went on automatically until the t/o punched for the route, but that couldn't be the case today. So who controls those holding lights at 5 Av? |
