100 Years of National Parks
Bay Point and Clayton Railroad Co and Cowell Portland Cement Co Railroads --
Rolling Through the Clayton Valley -
110 Years after Incorporation
Learn about this little-known 9-mile private short line railroad, incorporated on August 29, 1906, owned and operated by the Cowell Portland Cement Company (producers of ‘Mt Diablo Cement’), which ran from the cement plant & company town of Cowell (at the base of the Lime Ridge hills), crossing familiar roads, and alongside Mt Diablo Creek; rolling through bucolic scenery, a dairy farm, orchards and ranches of the greater Clayton Valley (much of today’s Concord Naval Weapons Station / future EBRPD  parkland), to Bay Point (today’s Port Chicago / Military Ocean Terminal Concord - MOTCO), terminating at the Santa Fe Railway interchange.
This exhibit will run through December 2016, and is open to the public at no cost, but donations are welcome.  Please visit the Clayton Museum page for viewing days and hours.
