So instead of getting 160 cars through in the peak hour, maybe you get 40.The one tube tph depends on service level used. They currently operate 20 tph in each direction simultaneously. If they operated 40 tph sequentially, they could nearly duplicate existing service levels over the hour. It's time the MTA showcased what CBTC can do. If CBTC isn't equal to the task, it should question the wisdom of continuing its installation. CBTC (or the lack of CBTC equipped rolling stock) has prevented operating the 14th St Line at its historic 24 tph peak service level. The MTA has not ordered sufficient CBTC rolling stock to operate the Flushing Line at its historic peak 36 tph service level. The MTA's CBTC rollout has not and will not increased service levels but frozen them at current levels. |
