The
J. G. Brill Company manufactured
streetcars, interurban coaches, and
buses in the United States for almost ninety years. The company was founded by
John George Brill in 1868 as a
horsecar manufacturing firm in
Philadelphia. Over the years, it absorbed numerous other trolley-interurban manufacturers such as Kuhlman in Cleveland and Jewett in Indiana. With business diminishing, in 1944 it merged with the
American Car and Foundry Company (ACF) to become
ACF-Brill. It ceased trolley and bus production in 1954, though some of their interurbans served the
Philadelphia area till the 1980'es. Brill was the longest lasting of the nation's trolley and
interurban manufacturers. It manufactured over 45,000 streetcars (trams; also known as trolleys or trolley cars in the U.S.),
motor buses,
trolleybuses and
railroad cars. At its height, it was the largest manufacturer of streetcars and
interurbans in the U.S. and produced more streetcars and interurbans and gas electrics than any other manufacturer.
