US Railroad Administration 0-8-0
United States 1916 175 produced
In addition to the light switcher with the 0-6-0 wheel arrangement, the USRA also designed a heavy switcher with the 0-8-0 wheel arrangement. Here, production was divided between the three manufacturers ALCO, Baldwin and Lima. A total of 175 locomotives were delivered to 21 customers under the administration of the USRA. After the dissolution of the USRA, a total of about 1,200 copies were built up to 1925. Only one of the copies survives today, Republic Steel Corp. No. 285 built by ALCO in 1925.
