Sacramento - Graniterock’s historic steam engine No. 10 is shinier and stronger than ever before thanks to an extensive overhaul of the boiler that started in 2011.

The oil-fired steam engine is back on track at the California State Railroad Museum in Sacramento, where it is used to pull passenger excursion trains on weekends along the levees of the Sacramento River.

The locomotive officially returned to service April 11.

Museum visitors can book train ride tickets online at or purchase tickets in person beginning at 10:30 a.m. the day of the ride at the Sacramento Southern Railroad ticket office on Front Street between J and K streets.

Graniterock purchased engine No. 10, built by the H.K. Porter Co. for the U.S. Army in 1942, from the Army Corps of Engineers after World War II.

The engine was used to haul rock from the company’s quarry near Watsonville before she was replaced with a General Electric 470-horsepower diesel locomotive switch engine in 1951.

Graniterock’s late President and CEO Bruce Woolpert had the rusty, broken engine restored to full working order in the 1990s and donated the engine to the Sacramento museum in May 1997.

Rose Ann Woolpert wrote a children’s book that features the engine and history of mining rock. It is called Engine No. 10. The book is available at the California State Railroad Museum and

Engine No. 10 was also featured in Steven Spielberg’s 2005 movie, Memoirs of a Geisha.
