Heartland of America Tour: Big Boy No. 4014

Twenty-five Big Boys were built during World War II, but only eight survived. No. 4014 is the only one of the eight still in operation and remains the world’s largest operating steam locomotive.

Admission to see the Big Boy is Free and Open to the Public.

A steam tracking map showing No. 4014’s location and route will be available at upsteam.com.

Note: All schedule times and locations are subject to change. The Big Boy can run ahead or behind schedule, based on conditions. Questions about the route? Check out our Steam Locomotive Tracking map, which has the planned route highlighted.

Union Pacific reminds all rail fans to keep safety top of mind and stay 25-feet back from the tracks when taking a picture or viewing the colossal locomotive. That means never take a picture or video standing on the track or the ballast and never climb on the locomotive or equipment.
