Posted by JournalSquare-K-Car on Fri Feb 29 22:07:10 2008, in response to Re: TA is obsessed with CBTC, and ''New'' tech for no reason., posted by North-Easten T/O on Fri Feb 29 07:40:25 2008. North-Eastern, so with CBTC, you have control of the train's speed? Is it like the HBLR system which tells you the maximum allowable speed, and cries if you overspeed?I thought it was fully automated robotrain with CBTC. But anyways, i have been on PATH trains who come up behind the leader, and start to enter as the leader is exiting. Happens often at grove street. Sometimes it is surprising to see a train leave, only to be followed by another less than ten seconds later. Gives a system a "rapid transit" feel. That being said, path uses the "dinosaur" system as NYCTA, but it isn't inefficient, and slow. By the way, the RIVER Line uses a form of this tripper system. It even has grade timers in areas. Instead of physical trippers that stand up, electromagnets become energized at the wayside and trip the train. I find it better than the HBLR system because the HBLR's crying is annoying, and it causes the train to jerk. |
