Union Pacific's No. 844 steam locomotive will return to the tracks this summer as part of the special Denver-to-Cheyenne train for Cheyenne Frontier Days.
The Wyoming Tribune Eagle reports that the engine has been out of service for the last three years while it underwent restoration at Union Pacific's steam shop in Cheyenne.
With repairs nearly complete, railroad officials have announced the 454-ton engine will be ready for service in time for Frontier Days in July.
No. 844 was the last steam engine built for the Union Pacific Railroad, delivered in 1944.
Since No. 844 was taken out of service, the Frontier Days Train sponsored by The Denver Post has been led by historic diesel locomotives.
