AMC #7, Ione, CA

This 2-6-2 (Prairie) type locomotive was a difficult prospect to photograph. When I visited, one side was cluttered with parked police vehicles and the other was awash from recent rainfalls.

The engine was built as #8 for the Mc Cloud River Railroad in 1901 by Burnham, Williams & Co., one of the early incarnations of the Baldwin Locomotive Works. In 1937, it was bought from McCloud River by the Amador Central Railroad, a shortline operating 12 miles between a connection with the Southern Pacific at Ione and Martell, CA. Renumbered #7, it worked from 1939 until retired in 1956.

The AMC passed through a number of owners before ending operations in 1997.
