World’s largest steam locomotive is rolling back through the Midwest in celebration of America 250 

The world’s largest operating steam locomotive is chugging its way back through the heartland this month, drawing massive crowds.

Union Pacific’s legendary Big Boy No. 4014 is currently completing a historic coast-to-coast tour celebrating America’s 250th anniversary.

The massive machine has already captivated onlookers across the East Coast, marking the first time it has steamed east of the Mississippi River since its original delivery in 1941. Now, the locomotive is making its highly anticipated return trip across the Midwest as it heads back to its home base.

After spending early July on the East Coast and celebrating Independence Day in Philadelphia, the tour is officially heading west.

“Union Pacific couldn’t be prouder to share this powerful piece of history with the nation and to be a part of America’s birthday celebration,” company CEO Jim Vena said.

Vena added the tour celebrates Union Pacific’s 164-year history and the people who helped build the railroad.

For those in Missouri who miss seeing Big Boy on the rails, St. Louis is home to the stationary No. 4006 at the National Museum of Transportation.
