Southern Pacific 5021
Southern California Chapter
Railway and Locomotive Historical Society
Locomotive number 5021 is the only remaining
member of a group of forty nine 4-10-2 Southern Pacific type engines which
were built between 1925 and 1927 for both passenger and freight service,
primarily for use on the line from Sacramento to Reno. The long driving
wheelbase proved detrimental to the rails on that line and all of the locomotives
were subsequently assigned to other portions of the system, ranging from
Portland, Oregon all the way to the end of Southern Pacific's Coast Lines
which terminated at El Paso, Texas.
The last years of number 5021's career
were spent in service largely in Oregon where she was assigned to the Portland
Division, remaining in operation until 1955. On March 8, 1956 the
locomotive was donated to the Railway and Locomotive Historical Society
for display at the Los Angeles County Fairgrounds. Number 5021 is
one of only four 3-cylinder steam locomotives know to exist in the United
States.
