The first in a series of books that will give the railfan and modeler an encyclopedia of Union Pacific diesels. The reference book series for Union Pacific diesel and turbine fans! The most complete roster/pictorial books published to date, the first two-volume set covers builder's data and dispositions of each member of this western carrier's diesel-electric and turbine locomotive fleet during the 1934-1982 period, as well as a varied selection of photographs detailing each model.
From the early EMC E units and giant GE-built gas turbines to the varied EMD SD40-2 fleet that moved transcontinental freight into the 1980s, all are covered. The dust jacket features a specially commissoned painting by Gil Bennet.
