Granite Rock Co. No. 10

Granite Rock Company No. 10 is an S100 Class 0-6-0 steam locomotive built in 1942 by H.K. Porter for the United States Transportation Corps.
From 1942 to 1947, the locomotive worked at the Army depot in Tracy, CA as locomotive 5001.
After World War II, Granite Rock bought the engine from the Army Corps of Engineers and put it to work hauling rock from the company’s quarry near Watsonville, until it was replaced with a General Electric diesel switcher in 1951. 
Granite Rock’s late President and CEO Bruce Woolpert donated the locomotive to the California State Railroad Museum in 1995, and was restored to full working order in May 1997, utilizing parts from USATC 5014.
Today the engine remains at the California State Railroad Museum. The locomotive is used for excursion train rides.
