Posted by randyo on Wed Jul 18 15:11:52 2018, in response to Re: Probably not credible, NY Post article, posted by Bill from Maspeth on Tue Jul 17 17:21:03 2018. The problem with the #4 Line incident was that the GT which was in effect only when the switch was set for the diverging route wasn’t far enough back so that the M/M didn’t have enough of a chance to slowdown sufficiently to take the switch at a safe speed. A similar arrangement existed approaching 72 St S/B on Bway but again in that case the start of the GT was not far enough away fo the M/M to slow down for the switch. Since that time the signals in that and similar locations have been adjusted so that there is plenty of time for the T/O to slow down to a safe speed. Actually, a new system has been installed in many locations using “wheel detectors” which when activated for a similar situation flash lunar white until the train has slowed to the proper speed and go steady once that speed has been reached. Unlike the older GT signals however, the stop arms on the wheel detector signals will come up under the train if the T/O should attempt to exceed the posted speed. |
