Loading ...Only 24 of the 4000-series “Big Boy” locos were made. There are several on static display at various railroad museums around the country. None were in running condition, but may have been static-rigged to whistle, lights, etc. Number 4014 was on display near the west Colton UP yard in California and was chosen for rebuild because it was in the best condition of all surveyed. That was in 2014. The UP steam shops have just finished the rebuild and these were pix of it’s first test runs. I don’t know how far into Colorado they took it on that test run. Then it took a trip to Ogden UT, double-headed with the other massive steamer UP #844 and a longer train.
The biggest steam locomotive ever built
lives again!
