p.m. to and from 181st Street. Only expresses starting and ending at Kingsbridge would run express in this section-expresses from 168th Street would make local stops in this section. The Kingsbridge express trains would have two red signal markets on the top of the front motor car and a red lantern carried on the front end of the train the center of the car platform. The previous schedule had local and express trains both running every four minutes south of Kingsbridge, while the new schedule had express trains running every 8 minutes on the express track north of 96th Street, and local trains running every eight minutes. The number of local trains south of 96th Street did not change, with half of express trains becoming locals at this point. Waits at local stations north of 96th Street were ten minutes. In December 1906, the IRT prepared plans to relieve overcrowding on the platforms at 96th Street and train congestion at the station. To reduce the significant number of people transferring between people taking Lenox Avenue Line locals and Broadway express trains, the IRT planned to have Broadway express trains pass through the station without stopping. This would force people wanting to take Lenox Avenue Line trains to do so further down the line without needing to transfer, allowing trains to move through 96th Street more quickly. In 1906, some of the local trains that started at 168th Street in the morning bypassed 157th Street without stopping. On January 23, 1911, ten-car express trains began running on the Lenox Avenue Line, and the following day, ten-car express trains were inaugurated on the West Side Line. On June 3, 1917, the first portion of the Broadway–Seventh Avenue Line south of Times Square–42nd Street (to 34th Street–Penn Station) opened. A separate shuttle service between Times Square and 34th Street was placed into service as well. On July 1, 1918, this shuttle was extended south to South Ferry, with a shorter shuttle on the Brooklyn branch between Chambers Street and Wall Street. Finally, the new "H" system was implemented on August 1, 1918, joining the two halves of the Broadway–Seventh Avenue Line and sending all West Side trains south from Times Square. Local trains (Broadway and Lenox Avenue) were sent to South Ferry, while express trains (Broadway and West Farms) used the new Clark Street Tunnel to Brooklyn. On January 16, 1928, the New
