The Sugar Pine Railroad
From Wikipedia: "The current railroad follows a portion of grade originally carved into the mountain by the Madera Sugar Pine Lumber Company in the early 20th Century. The company originated in 1874, when it was organized as the California Lumber Company to log the area surrounding Oakhurst, California. The Madera Sugar Pine Lumber Company once had a large sawmill at Sugar Pine, California. Due to the onset of the Great Depression and a lack of trees, the operation closed in 1931. But the graded right-of-way through the forest remained, enabling the Stauffer family to reconstruct a portion of the line in 1961. The current railroad utilizes locomotives, converted log disconnect cars, and other railroad equipment purchased from the West Side Lumber Company after it ceased railroad operations in 1961."
