UP 4021
Title:  UP 4021
Description:  Big Boy 4021 departs Harriman with an extra westbound. Harriman was a small railroad community, and most of it is pictured here. The main housing were UP employee bunkhouses in a row on the north side of the tracks. The UP coal tower and water tower were located on the south side of the tracks, along with speeder shacks and a sding for incoming coal hoppers. With the dissappearance of steam from UP, Harriman became obsolete, as diesels did not require a fuel stop when crossing the Wasatch. The coal tower was gone by 1976, and today, the town is mostly abandoned. Obtained from Union Pacific Steam: Big Boy Portraits (Bush, Ehernberger)
