231st Street

The 231st Street station is a local station on the IRT Broadway–Seventh Avenue Line of the New York City Subway. Located at the intersection of West 231st Street and Broadway in the Kingsbridge neighborhood of the Bronx, it is served by the 1 train at all times.

This station opened on January 27, 1907, as 230th Street station. It was built near the site of the originally proposed northern terminus of the IRT Broadway–Seventh Avenue Line at Bailey Avenue and 230th Street, a block southeast of the current station. It was also located near two former Kingsbridge railroad stations owned by two separate railways inherited by the New York Central Railroad; one was along a former segment of the Spuyten Duyvil and Port Morris Railroad (now the Hudson Line), and the other was for the New York and Putnam Railroad (now abandoned). To address overcrowding, in 1909, the New York Public Service Commission proposed lengthening the platforms at stations along the original IRT subway. As part of a modification to the IRT's construction contracts made on January 18, 1910, the company was to lengthen station platforms to accommodate ten-car express and six-car local trains. In addition to $1.5 million (equivalent to $51.8 million in 2025) spent on platform lengthening, $500,000 (equivalent to $17.3 million in 2025) was spent on building additional entrances and exits. It was anticipated that these improvements would increase capacity by 25 percent. The northbound platform at the 231st Street station was extended 50 feet (15 m) at both its north and south ends, while the southbound platform was not lengthened. Six-car local trains began operating in October 1910, and ten-car express trains began running on the West Side Line on January 24, 1911. Subsequently, the station could accommodate six-car local trains, but ten-car trains could not open some of their doors. The city government took over the IRT's operations on June 12, 1940. Platforms at IRT Broadway–Seventh Avenue Line stations between 103rd Street and 238th Street, including those at 231st Street, were lengthened to 514 feet (157 m) between 1946 and 1948, allowing full ten-car express trains to stop at these stations.
