Union Pacific Wooden Caboose Rosters
By Don Strack
The Equipment Register begins with the UP 2000 series. The car ownership records of the subsidiary railroad companies, OSL, OWR&N, and LA&SL, were kept separately by those companies, until the records were consolidated, sometime in the late 1940s or early 1950s. The listings for the OWR&N 200-series cabooses, OSL 600- and 700-series cabooses, and UP 1000-series cabooses are taken from the "Converted or Changed From" column on the register pages.
The general 1885 renumbering assigned Union Pacific cabooses to the 2000-2499 series, and the renumbering from the 1000-1999 series reflects that general renumbering effort. Some of the cars may not have been cabooses originally. Union Pacific had several passenger coach and chair cars in the 1000 series which were rebuilt to cabooses. Only those cars which were likely to be cabooses due to their 30 feet length are shown, the others more likely being ex-passenger cars. Note that most of the cars were renumbered to the 2000 series during 1885 and 1895.
