In partnership with Friends of No. 9, the California State Railroad Museum will display the beautifully restored No. 9 steam locomotive beginning in July. No. 9 is the only surviving locomotive of the Mount Tamalpais Scenic Railway, a tourist railroad in the late 19th and 20th centuries that enabled tourists to leave the city and enjoy the scenic beauty of Mount Tamalpais and, later, Muir Woods.
The Heisler locomotive dates back to 1921 when it was purchased by the Mount Tamalpais and Muir Woods Railway of Mill Valley. The locomotive operated on the rails of the “Crookedest Railroad in the World,” a scenic tourist railway known for its steep and winding route between Mill Valley and the east peak of Mount Tamalpais. In 1924, the locomotive was sold and spent the next two and a half decades working for lumber companies in Siskiyou and Humboldt counties. Then in 1953, the Pacific Lumber Company bought the locomotive for display next to its new museum in Scotia. The locomotive was later put up for auction in 2018 when a group of dedicated rail fans joined together to raise funds to secure No. 9 and begin restoration. The dedicated group was steadfast in their focus to return No. 9 to its Mt. Tamalpais roots and viewed it as the “last piece of a lost era.”
Carefully researched, the meticulous restoration work began in 2019 and will be completed in 2025. The historical locomotive remains an important piece of logging, tourist and rail history.
“The restoration of the No. 9 represents the very best impulses of the preservation community,” said Director of the California State Railroad Museum Ty Smith. “Although the locomotive won’t steam passengers up Mt. Tamalpais, it serves as a window into a remarkable episode in California History. We’re grateful to be able to share in telling this important story.”
The prized No. 9 steam locomotive will be on display in the Museum’s Roundhouse until January 2026. Open daily from 10 a.m. to 5 p.m. For more information about the California State Railroad Museum and Foundation visit californiarailroad.museum.
