That's still only 80% of what they had before the CBTC investment.

But as Easy noted that throughput was achieved with less regard for the operator's liability in the event of a problem. The MTA (and most transit systems) simply do not trust their operators enough to go back to those policies which provide provide no confirmation to the supervision and management that their policies are being obeyed and their backsides are firmly covered.

The CBTC system provides the means for the MTA to loosen the reins on their operations while still maintaining the sort of positive control their numerous timers failed to provide. The degree to which they achieve what the BMT managed to do two generations ago at 8th St is entirely up to the management and the degree to which they trust the black boxes driving and the train making the stop. If they decide they can run that equipment in the same manner the station was utilized once upon a time, then we'll see if they're capable of turning 24 trains per hour at the station. If they prove to be a bit more risk averse, as I'm sure many here would expect, then we'll see a somewhat lower utilization of the 8th St Station.

But it's not the signal system, it's the management and the feedback they receive from the signal system which will ultimately determine to what degree the 8th St Station can fulfill the Canarsie Line's demand. But IMHO it's foolish to embark upon a very costly platform lengthening project when we do not even know if the MTA will choose to use the CBTC system to its fullest.
