But extending the platforms is an extremely expensive undertaking for an increase in capacity that is less than the far more affordable signaling system upgrades. If we're picking between either implementing CBTC or lengthening trains, then one would have to go with CBTC and shorter headways, particularly if it were paired with OPTO implementation to mitigate the labor costs that would otherwise result. If we're dealing with the Canarsie Line going forward, then a viable next step would be to ensure all equipment is CBTC equipped so as to fully utilize that investment and determine the maximum capability of the system to turn trains at 8th.Beyond that if further capacity growth is warranted by demand then one would have to make the difficult choice between two expensive alternatives. We can either extend the platforms and the trains, or extend the Canarsie line to a station where throughput can be improved. But why leap to the expensive alternative when there are low hanging fruit which can yield further performance improvements at little or no cost compared to rebuilding every line on the platform. |
