This working railroad has been in operation since the 1890s and is now operated by the California State Railroad Museum in Sacramento. Self-guided tours are available during park hours, which are 9:30 a.m. to 4:30 p.m., April through October, and 10 a.m. through 3 p.m. in the winter months. One summer and fall weekends, train rides are available on a historic steam or diesel train, taking passengers through California’s Gold Country. The rides are 45-minute, 6-mile roundtrip rides. During the winter, the train operates an official Polar Express.
