In 1998, a condition existed that required the compete replacement of the subway floor along a section of the Lenox Ave Line. Passenger volume and network constraints were such that bus substitution was not a viable option. Rail service needed to continue, at least in one direction throughout the project. In response, a creative but operationally challenging one-way, reversible service plan was developed that would provide subway service in the peak direction with replacement bus service provided for the reverse peak. Reverse train movements would operate on an alternate line.
Mr. Gaul was responsible for developing and implementing the operating plan to support the project. Because of the inter-connected nature of the system, the operating impacts of this project affected virtually all aspects of the Division. Completely new operating schedules were required on most lines. The temporary loss of operational flexibility resulted in the need for specialized delay management and restoration of service procedures, along with targeted investments in additional operational flexibility. Lexington Ave., already the most overcrowded corridor in the system would see even more train volume. We developed additional service management techniques to address the needs of this project. These measures were made permanent after the completion of the project.
The modified operation was highly successful, and the project completed on time and on budget.
