BMT (Brooklyn-Manhattan Transit)

The Brooklyn-Manhattan Transit (BMT) was a major part of New York City's rapid transit system, operating subway and elevated lines primarily in Brooklyn and Manhattan. Originally established in the early 20th century, it was one of three companies that built and managed subway services before they were unified under city control in 1940. The BMT contributed many of the city's distinctive subway routes and train cars, and its lines still serve thousands of commuters daily as part of the modern subway system. Essentially, the BMT helped shape the development of New York City's transit, making it a vital transportation network.
