Union Pacific 737 (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Union Pacific Railway Engine No. 737 or UP 737 is a 4-4-0 steam locomotive. It is currently the oldest preserved Union Pacific steam locomotive. It was originally acquired by the Union Pacific Railroad in 1887. It is one of about 115 surviving American 4-4-0s in the United States(around 30 4-4-0s if reproductions are not counted) of which about 60 are operational.UP 737 began its career as part of one of the largest locomotive orders on record up to that date, for use on Union Pacific passenger and freight trains. As delivered, the locomotive had a long, pointed, vertical bar wooden pilot, an oil "box" headlight, a "diamond" stack of the shallow diamond style peculiar to the Union Pacific at that period. It had steam and sand domes that appeared comparatively square in profile and lacked the common, ornate, cast-iron dome "rings," a decorative molding that dressed up the appearance of such domes and that many 19th century locomotives sported.
