The Brotherhood of Locomotive Firemen and Enginemen (B of LF&E) was a North American railroad fraternal benefit society and trade union in the 19th and 20th centuries. The organization began in 1873 as the Brotherhood of Locomotive Firemen (B of LF), a mutual benefit society for workers employed as firemen for steam locomotives, before expanding its name in 1907 in acknowledgement that many of its members had been promoted to the job of railroad engineer. Gradually taking on the functions of a trade union over time, in 1969 the B of LF&E merged with three other railway labor organizations to form the United Transportation Union.
