No, but it does allow the train directly behind the one at Roosevelt to get in the station more quickly.That's not really true. The blocks leading into stations are much shorter than between stations. There are also timers that limit the approaching train's speed, when it is close to the leaving train. This permits following trains to creep into stations at the same speed as one controlled by CBTC. N.B. a train that creeps into a station is taking more time to decelerate and come to a stop than one that approaches the station at full speed. Longer deceleration times mean longer headways mean less capacity. Introducing a "safe" version of keying with CBTC does not increase capacity. |
