have helped relieve overcrowding on the IRT Lexington Avenue Line, which is the busiest line in the country. Under Phase 2 of the Program for Action, the Pelham Line would have been extended to a modern terminal in the Co-op City housing complex. Due to the 1975–1976 fiscal crisis that affected the city, most of the remaining projects did not have funding, so they were declined. Expected to be completed by the mid-1970s and early 1980s, lines for the Program for Action had to be reduced or canceled altogether due to the 1970s fiscal crisis. Extent and service The following services use part or all of the IRT Pelham Line: Express service operates between Parkchester and Third Avenue–138th Street during weekdays from approximately 6:30 a.m. to 8:45 p.m. At those times, Pelham Bay Park cannot handle the large number of 6 and <6> trains in service. As a result, 6 trains run local on the Pelham Line south of Parkchester and short turn there. <6> trains make all stops north of Parkchester, then run express using the center track between that station and Third Avenue–138th Street in the peak direction. At all other times, 6 trains run local on the entire line. Route description Beginning at a junction with the IRT Jerome Avenue Line north of the Lexington Avenue Tunnel at 135th Street, the IRT Pelham Line runs beneath 138th Street for the first three stations in Mott Haven, then curves to the northeast along eastbound Bruckner Boulevard before shortly curving north again along Southern Boulevard. After 145th Street at Samuel Gompers High School, the line curves to the northeast continuing to run under Southern Boulevard. The line returns under eastbound Bruckner Boulevard again, only to leave at Whitlock Avenue and begins to emerge from underground at Aldus Street. The line is transformed into an elevated line over Whitlock Avenue at East 165th Street, but shortly after this encounters the Whitlock Avenue Subway station and curves east over Westchester Avenue which runs over Sheridan Boulevard, the Harlem River and Port Chester Railroad line, and the Bronx River. The line remains over Westchester Avenue throughout the rest of its journey. East of Morrison Avenue station, the road runs over the Bronx River Parkway, and enters Parkchester. The station named after the neighborhood runs over the Hugh J. Grant Circle, which is also over the Cross Bronx Expressway. East of Castle Hill
