Planned service pattern When the construction of the Second Avenue Subway's Phase 3 is completed, the proposed T service will operate from Harlem–125th Street to Houston Street. After Phase 4 opens, T service will run the full length of the line, from Harlem–125th Street to Hanover Square. The new T service is planned to operate at a frequency of 14 trains per hour during rush hours. As planned, the T will use the following lines with the same service pattern at all times. Planned station listing Should Phase 3 of the Second Avenue Subway be built, the proposed T route would run entirely in Manhattan and would be the only non-shuttle New York City Subway service to run only within one borough.
