Oh, definitely they are required, as you said, because not enough R143 cars were ordered (which is just shocking, really); the R160s without CBTC equipment are functionally equivalent to the R42s they replaced, at least to the senses of the signal system, which can't locate them in a given fixed block. But I'm unclear on why it has to wait until the entire R160 orders are completed, i.e., when they get to the last 80 cars.One other thing - has CBTC been any effective in re-routes and single-tracking by ability to re-shape the signal blocks? It doesn't seem like it, so insofar as I can tell, CBTC is not a moveable block system as implemented, it seems a lot more like a fixed block system that allows for safe movement within or quite near an occupied block at or below the correct speed. |
