Big Boy

The world's largest steam locomotive returns to the rails.

Big Boy Returns!

One of the biggest and most powerful steam locomotives in history is coming back to life: Union Pacific’s Big Boy.

Big Boy weighs in at 600 tons, is 132 feet long, and can move at up to 80 mph while pulling a fully loaded freight train with the force of about 7,000 hp. Union Pacific introduced the first of 25 of these steam locomotives in 1941 and retired them from active service in July 1959. 
Several 4-8-8-4 locomotives later went to museums around the United States for preservation. In 2013, Union Pacific bought back Big Boy No. 4014 from a museum in Pomona, Calif., to restore and operate. The restoration in 2019 is timed to celebrate the completion of the first Transcontinental Railroad in 1869.

Come here to learn all about Big Boy, watch videos, see beautiful photo galleries, and share stories about one of the world’s biggest steam locomotives.
