BU cars is the generic term for BRT elevated gate cars used on predecessor lines of the New York City Subway system. Various orders of these cars were built by the Osgood-Bradley, Brill, Cincinnati, Laconia, Pullman, Gilbert & Bush, Harlan & Hollingsworth, Wason, Pressed Steel, Brooklyn Heights Railroad, John Stephenson, and Jewett car companies.[1]
These cars consisted of a variety of equipment used on the BRT and later BMT. Some cars were inherited from steam railroads that became part of the BRT, while others were built new for the BRT as late as 1907. In 1913, the BRT introduced an advanced steel car design for subway service (the AB Standard), thus ending BU cars' production.
The term BU was derived from the Brooklyn Union Elevated Railroad (BUERR) Company, one of the last operating companies of Brooklyn elevated lines before the BRT formed the New York Consolidated Railroad in 1912 to absorb the BUERR and other properties.
Historians disagree as to whether the term "BU" was commonly used before the BMT was purchased by the City of New York in 1940, or whether it was mainly an introduced term to describe the wooden elevated cars of the former private company.
The primary distinguishing feature of BU cars is that they were elevated cars built mostly or substantially of wood, with or without steel frames, where passenger access to the cars was provided by open platforms at both ends of each car. A trainman between each pair of cars manually opened and closed folding gates to admit or bar passengers from entering or leaving.
All gate cars used in BRT elevated service can be described as BUs. This excludes several classes of elevated equipment:
The BU cars should not be confused with the Manhattan El cars, a series of gate cars that were operated by the Interborough Rapid Transit Company.

These cars are the oldest operational members of the New York Transit Museum fleet. Those built in 1907 were the last BU cars ever built. They are fully operational and are occasionally used on museum-sponsored excursions; however, when the excursion goes through underground subway tunnels, they must be towed by steel cars. For safety reasons, passengers may not ride in these cars in subway tunnels; non-employees must ride in the accompanying steel cars during the tunnel portions of the trip.
The three museum BUs are currently numbered and coupled as 1407-1273-1404. They were rebuilt from Q-type unit 1622A-B-C in the late 1970s. As part of the June 22, 1965 "Transit Day" commemoration at the World's Fair, Q-type 1622A-B-C were rehabilitated and repainted in the original colors used for the 1939–40 World's Fair, blue and orange,[3] which are also the colors of the New York City flag. After they were converted back into gate cars, they were given their original numbers and received the red paint scheme that they originally wore when they were brand new.
Besides the three cars preserved at the New York Transit Museum, many other still-extant cars have been preserved;[4]
