No. 4014 when it was in operation
The initial phase of preparation for moving the Big Boy UP 4014 from Pomona, Calif., to Cheyenne is moving according to plan, the company said in mid-August. Members of the U.P. Steam Team have been in Pomona since early August, and will return later in the month for additional assessments, according to an Aug. 15 U.P. announcement.
Union Pacific reached an agreement in July with the Southern California Chapter of the Railway and Locomotive Historical Society in Pomona to return Big Boy No. 4014 back to U.P. It has been on display in Pomona since 1962.
No. 4014 was built in 1941 and it ran for about 20 years. It was built to pull big trains through the mountains during World War II.
Only 25 Big Boys were ever built and only 8 remain. They are the world's largest steam locomotives, weighing about 1 million pounds each.
The 4014 will be restored, a job that is expected to take 3-5 years.
According to maintenance records, No. 4014's last routine repairs took place in 1956, after which it was in service for 41,000 miles, and then was retired, UP said.
It is expected to be powered by diesel locomotives for the move.
A Big Boy was recently moved in Texas. Several empty freight cars were attached to provide braking action.
Ed Dickens, senior manager-Heritage Operations, said he's enjoyed the enthusiastic support of everyone involved with moving No. 4014.
