Even the new signal system has it's limits.As does adding two cars to every train. In fact that limit is 125% and it's far more fixed than any signaling system change. Actually the limit is a bit less than 125% since the eight car train will clear interlockings and so on faster. Adding 2 cars to every train adds capacity without adding trains or incurring more labor costs. Unless the MTA opts for R143-compatible married pairs and peak period cuts and adds those two cars will have a very definite cost. Maybe that cost won't come in labor, but they'll be forced to provide a per-train capacity for rush hour on a 24/7 basis and the additional capacity will need to be paid for. Those two additional cars will rack up a lot of VMTs providing no noticeable reduction on crowding during the other 16 hours of the day that aren't part of the peak period. Seeking capacity increases with throughput improvements at 8th to maximize the benefit of the CBTC system provides a flexibility in dealing with rush hour, the shoulder periods, the midday, and overnight. And of course if the MTA would buck up and make OPTO a priority for ATO/CBTC equipped lines they'd achieve cost reductions on the labor side even as they increased the number of trains being operated. |
