Focus On… Big Boy Train

The world’s largest operational steam engine will thunder across Colorado in September, giving residents yet another opportunity to see this big locomotive up close and personal on Labor Day weekend.

Known as “Big Boy” to train aficionados worldwide, Union Pacific No. 4014 left Cheyenne in August, passing through Julesburg briefly on its way to North Platte as the showcase of “Rail Days 2021.” Big Boy then traveled all the way to New Orleans before returning to Colorado for only the second time in two years on Sunday, September 5, when it rolls through Kit Carson at 10 a.m., arriving in Denver at 7 p.m.

This popular Union Pacific train will be on public display in Denver on Monday, September 6 at 39th and Wynkoop Street from 9 a.m. to 3 p.m., before departing at 8 a.m. on Tuesday, September 7, on its way back to Wyoming.
