2015 marks not only the 100th anniversary of the BMT, but also the 75th anniversary of the unification of the New York City subway system. The first city-owned and operated subway line went into service in 1932 with the Eighth Avenue line of the Independent Subway System (IND). However, the idea for a unified municipal subway system was much older. Originally conceived by Mayor John Hylan in the 1920s, the unified subway system would finally come into being in June of 1940 after years of negotiations. The city purchased the financially insolvent IRT and BMT and with the IND the entire system was now under the control of the city’s Board of Transportation. The IRT lines became the A Division, while the wider and longer trains of the former BMT and IND became the B Division, which they remain today.
