The problem is that even if the leading train has cleared the station, it would not be safe operation for the following T/O to accelerate to 30 MPHI'm assuming you are referring to the second scenario - follower stops for red signal 300 feet before station and proceeds when that signal turns green (not yellow). There is always a tripper at least 300 feet behind the leader's rear under this scenario. The stopping distance using service brakes of 2.5 mph/sec is 264 ft. The stopping distance with emergency brakes of 3.2 mph/sec is even less. The service brakes alone would stop the follower 36 ft short of the leader's rear. |
