Subway cars can easily stop in 100 feet if they operate slowly enough.Thus my speculation that CBTC incorporates a speed control element. The presence of CBTC allows the trains to do so regardless of the fixed block boundaries and is a fail-safe against the misjudgments of a T/O. Well, let's not go THAT far; life has a way screwing things up in mysterious ways. You build a good system, cross your fingers, and watch out for potential trouble so that you can go on to build a better mousetrap if need be. A trivial weakness given that the MTA will have sufficient new rolling stock within a year or so to supply the necessary rolling stock. Trivial weakness? Hardly. More like HUGE oversight and ignorance. I have no problem saying that one or more people should face action over that poor judgment. How on earth were they going to operate CBTC successfully without trainsets that could operate using CBTC? |
