Union Pacific #8444 - possibly the most photographed locomotive in the world - with a Rocky Mountain Railroad Club excrusion at mile 30 on the Dent Branch.

Orignally numbered #844, it was the last steam locomotive delivered to the Union Pacific Railroad. Built by Alco, in 1944, it worked the railroad's premier transcontinental passenger trains until replace by diesel locomotives in the 1950's. Its final years in regular service were spent handling freight trains across Nebraska. In 1960, a fateful decision to place the locomotive in special service saved it from the being scrapped. To avoid conflict with the newly delivered 800-series of GP30 locomotives, #844 was renumbered #8444 in 1962. This was rectified in 1989 when its original engine numbers were restored. During the past four decades, the locomotive has been used for excrusion service and static display at special events. Thank you to the Union Pacific for preserving and sharing with the public this locomotive, possibly the finest example from the age of steam.
