Many people were up before dawn for a chance to see one of the largest steam locomotives ever built on the rails once again after sitting in a museum at the Los Angeles County Fairgrounds in Pomona for more than 50 years.
The locomotive is being towed all the way to Cheyenne, Wyo., where it will be fully restored and made to run on steam once again.
"Lots of mechanical work, all the drivers, new tires, axles, wheels -- many, many new components to make the locomotive serviceable," said Ed Dickens with Union Pacific.
Railroad fans came from all over to watch. Brandon Bedke's dad says he wouldn't allow his son to miss this big day.
"Pulled him out of school because this is a once in a lifetime opportunity to see something like this," said Chris Bedke of Rialto.
When Big Boy 4014 returns, it will be under its own power and you'll be able to ride it. But that won't be for at least another five years.
