50th Street station (IRT Broadway–Seventh Avenue Line) instance of metro station
To address overcrowding, in 1909, the New York Public Service Commission proposed lengthening platforms at stations along the original IRT subway.: 168  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 $43.6 million in 2021) spent on platform lengthening, $500,000 (equivalent to $14,541,000 in 2021) was spent on building additional entrances and exits. It was anticipated that these improvements would increase capacity by 25 percent.: 15  Platforms at local stations, such as the 50th Street station, were lengthened by between 20 and 30 feet (6.1 and 9.1 m). Both platforms were extended to the north and south.: 110  Six-car local trains began operating in October 1910.: 168  The Broadway–Seventh Avenue Line opened south of Times Square–42nd Street in 1918, thereby dividing the original line into an "H"-shaped system. The original subway north of Times Square thus became part of the Broadway–Seventh Avenue Line, and all local trains were sent to South Ferry.In December 1922, the Transit Commission approved a $3 million project to lengthen platforms at 14 local stations along the original IRT line, including 50th Street and five other stations on the Broadway–Seventh Avenue Line. Platform lengths at these stations would be increased from 225 to 436 feet (69 to 133 m). The commission postponed the platform-lengthening project in September 1923, at which point the cost had risen to $5.6 million.
