About the type: R44 (New York City Subway car)
The R44 is a New York City Subway car model built by the St. Louis Car Company from 1971 to 1973 for the B Division and the Staten Island Railway (SIR). The cars replaced many R1–9 series cars, and all remaining 1925 Standard Steel built SIRTOA ME-1 trains, providing Staten Island with a new fleet of railcars. The R44 fleet initially consisted of 352 cars; the remaining ones operate on the Staten Island Railway.
