UP 4014, the only 4-8-8-4 "Big Boy" steam locomotive in operation, pulls a 25 car long passenger special over the 3,800 ft high summit of Cajon Pass on Oct. 12, 2019. Fans from all over came out in drones in order witness this rare machine make a historic trip across Southern California's high desert. The passenger special was held for the Rail Giants Museum, where UP 4014 was before restoration, and was a weekend trip from West Colton to Barstow, and back to West Colton the following day. All ticket proceeds went directly back to the museum.
