Madison is a passenger rail station along CTrail's Shore Line East commuter rail line, which runs on the Northeast Corridor between New Haven and New London. Madison station consists of a mid-sized parking lot and one high-level side platform on the southbound side of the tracks. Madison is a commuter-only station; Amtrak's Acela Express and Northeast Regional services run through the station without stopping. Madison is served by about 11 Shore Line East trains in each direction on weekdays and 5 in each direction on weekends. History New Haven Railroad The New Haven & New London Railroad was charted in 1848, began construction in 1850, and opened for service in July 1852. A station similar to other on the line was located off Wall Street just north of downtown Madison. The line was owned by the New York, Providence and Boston Railroad (the "Stonington Road") from 1858 to 1862, and by the Shore Line Railway from 1864 until it was acquired by the New York, New Haven, and Hartford Railroad (the "New Haven") in 1870. In 1896, the original station was replaced by a saltbox station of a standard New Haven design, located slightly to the west. The older station was moved for use as a freight house. A small wooden westbound shelter, similar to other Shore Line stops east of New Haven, was added in the 1950s. Most commuter service east of New Haven ceased on January 1, 1969, after the New Haven merged into Penn Central, though the Clamdigger continued operation under Penn Central and later Amtrak until January 28, 1972. The shelter was likely demolished around 1973, as were other such shelters at recently closed stations. A second version of the Clamdigger operated from September 9, 1976 to October 30, 1977, but it did not stop at Madison. The Clamdigger was reinstated on January 8, 1978, with commuter-based flag stops added at Groton, Clinton, Madison, Stony Creek, and Branford. It was replaced by the Boston-New Haven Beacon Hill effective April 30, 1978. The Beacon Hill was discontinued on October 1, 1981, ending service to Madison a second time. In 1969, the 1896-built station was renovated as a showroom for a model home company. It is still in place, although the canopy was removed in the late 1990s during electrification work, and an expansion in 2005 modified its shape. In 1985, the 1852-built station was moved for possible
