MASON CITY, IA (KTTC) — Crowds of people gathered around the railways of Mason City on Tuesday to catch a glimpse of the world’s largest locomotive steam engine.
The Big Boy No. 4014 steam engine was built in 1941 and retired in 1961.
The engine is currently on a month-long tour across the Midwest to commemorate the transcontinental railroad’s 150th anniversary. The tour will end August 8.
It took two years to restore the locomotive before its current tour, according to Union Pacific.
The train arrived in Albert Lea, Owatonna, Northfield and St. Paul on Wednesday and will remain on display in St. Paul until it departs July 19. Click here for more information about the locomotive’s schedule.
