New york city union railway company c 1894
The Union Railway Company of New York City often shortened to Union Railway was chartered in 1892, and consolidated several streetcar transit franchises across Manhattan and The Bronx in New York City in the late 19th century. The Harlem Bridge, Morrisania and Fordham Railway established in 1863 combined with the North Third Avenue and Fleetwood Park Railway and the Melrose and West Morrisania Railroad to form the nucleus of the Union Railway in 1892. All lines were electrified the same year. Union Railway was acquired by Third Avenue Railroad Company in 1898, which was later reorganized as the Third Avenue Railway.
