Granite Rock Co. 10 is an S100 Class 0-6-0 locomotive built in August 1942 by H. K. Porter originally as U. S. Army 5001. In 1947 In 1960 the locomotive was sold to the Granite Rock Company. In 1995 the locomotive was sold to the California State Railroad Museum and was undergoing restoration into operating condition in 1997. In 1999 the engine participated at railfair 1999 in Sacramento alongside with Eureka (locomotive), SERA 28, MEL Co. 1, SP 4449, UP 3985, UP 844, AT&SF 3751, and a newly restored SP 2467 where V&T Genoa, AT&SF 1010, NWP 112, UP 4466, and SP 4294 live. Along the way SP 4449 and MEL Co. 1 had to pose right next to MCRR 25 for a picture and set off again. UP 4466 did a last year run before being retired and put back on display. Suddenly UP 844 had suffered a tube and at the end, UP 3985 had to take UP 844 home dead in tow back to Cheyenne Wyoming. In 2005 the engine appeared in a movie called Memoirs of Geisha. In 2007 the engine was in a tripleheader with QR 2, and RD Co. 3. In July 2011 it was withdrawn from service and was being restored into operating condition. In April 11, 2015 the locomotive was back in service. As of 2023, the locomotive is still operational.
