UP 9000
Union Pacific No. 9000 is a 4-12-2 steam locomotive built in 1926 by Alco for the Union Pacific Railroad.

This engine was designed to haul passenger and freight trains on the Union Pacific railway.

The UP took delivery of ten three cylinder FTT-1 4-10-2s in 1925 (#8000 & #8800-#8808), but these were not a great success.

By then, however, the UP had already committed itself to purchasing the massive 4-12-2 as a three cylinder locomotive from Alco, although problems with the Overlands at least allowed the company to modify the design during its development.

It was delivered to the Omaha, NE, shops on 8th April 1926 and, after some final work there, was moved to the depot for display west of the passenger station on May 13th.

The following day, #9000 moved west, starting out on the old main line from Omaha, part of the original transcontinental railroad bypassed by a later UP realignment.

The first test was on the 16th May, over Sherman Hill. Strings of cars lined Highway 30 just west of town as people came to see the new engine. Arriving at Laramie after midnight, it underwent a complete inspection and lube before continuing testing well into June, running up 4,159 miles.

The locomotive was inspected at each division point, finally arriving at Cheyenne, WY, just after midnight on the 15th of May.

Once out of testing, #9000 was assigned to the Laramie roundhouse where it operated as part of the freight pool and was shopped according to mileage schedules.

Today this big engine is a static display at The Southern California Chapter of the Railway and Locomotive Historical Society.

TriviaEdit
