Soon after the opening weekend of the 32nd consecutive season of excursion train rides on the Sacramento Southern Railroad on Easter weekend (April 4 & 5, 2015), California State Parks and the California State Railroad Museum are pleased to announce vintage steam locomotive Granite Rock No. 10 will return to service on April 11, 2015. First introduced in May 1997 by the California State Railroad Museum, Granite Rock No. 10 was taken out of service in 2011 for extensive boiler repairs during which time diesel locomotives pulled the excursion trains. Granite Rock No. 10 is an oil-fired steam engine built by the H.K. Porter Co. for the U.S. Army in 1942.
