Steamtown National Historic Site is hosting a visit from Union Pacific Big Boy No. 4014, the largest operating steam locomotive in the country, as it makes its way from coast to coast to honor America's 250th birthday. Don't miss this once in a lifetime opportunity to see No. 4014 reunited with Steamtown's own Big Boy No. 4012! It'll be the only place to see two Big Boys lined up side by side and for two weeks in June Steamtown National Historic Site will be the center of the railfan universe!

The park, in partnership with Union Pacific, is offering two public display days on Monday, June 15 and Tuesday, June 16. Visitors can get up close and personal with both Big Boys, visit the Union Pacific Museum Experience car, and check out two Union Pacific special commemorative diesel engines (No. 1616 and No. 1776) on display in our core complex. Steamtown's History Museum, Technology Museum, Roundhouse, and Visitor Center will also be open for all visitors.

No. 4014 will remain at Steamtown from June 17 through June 30 while Union Pacific completes servicing and a boiler wash on the locomotive. Both Big Boys will remain on view during that time, though viewing of No. 4014 may be more distant than the up-close opportunity on the public display days. See here for entry reservations for June 17-30.
