The 174th Street station is a local station on the IRT White Plains Road Line of the New York City Subway. Located at the intersection of 174th Street, Southern Boulevard and Boston Road in the Crotona Park East neighborhood of the Bronx, it is served by the 2 train at all times, and the 5 train at all times except late nights and rush hours in the peak direction.

The White Plains Road Line is a rapid transit line of the A Division of the New York City Subway serving the central Bronx. It is mostly elevated and served both subway and elevated trains until 1952. The original part of the line, the part opened as part of the first subway was called the West Farms Division, and the extension north to 241st Street as part of the Dual Contracts was called the White Plains Road Line. Eventually, however, the two parts came to be known as the White Plains Road Line.
