Hudson Division

Former New York Central main line between Croton Harmon and Albany. At the time, much of the route had four tracks. The electrified territory between New York City and Croton Harmon still is mostly four tracks, while third and fourth tracks beyond electrified territory were removed during the 1960's, with the installation of CTC. Commuter trains continue to be operated by Metro North, between New York City and Poughkeepsie

Unlike other track diagrams at this Web site, these track diagrams do not include switches, especially at interlockings, due to an unavailability of older track charts. But employee timetables included locations of all signals. Manual interlockings with towers are indicated with blue rectangles, interlockings were identified by number or letter included within the rectangles. Remote interlockings are indicated with red rectangles.
