UP Greeley Subdivision

The Greeley Subdivision is a Union Pacific mainline that goes from Denver to near Cheyenne, passing through Brighton, La Salle and of course, Greeley.

History
The line first started in 1870 after being built by the Denver Pacific Railway and Telegraph Company as an easy way to get from Denver to Cheyenne Wyoming. Denver Pacific merged with Union Pacific railroad in 1880, therefore the line became UP's line to operate. UP continues to operate this line today, and even runs it's two steam locomotives, UP 844 & UP 4014, on this line for excursions.
