Railfanning at Hampton, Oregon, on July 20, 1997

I took these pictures at Hampton, Oregon, on July 20, 1997. This location is Union Pacific's the former Southern Pacific's Cascade Line, also known as the Natron Cutoff. This has always been a busy line, and all of these trains passed through with a short period of time, and all were northbound. It had been less than a year since Southern Pacific had been merged into Union Pacific, but the effects of the merger were already very evident in the locomotive consists of these trains.

The first train we saw was a freight train led by Union Pacific #5048, a 3,600-horsepower SD50 that was built by the Electro-Motive Division of General Motors in December 1984. It was originally delivered in Union Pacific colors but with Missouri Pacific lettering. It was relettered for Union Pacific in August 1990.

The second unit in the train, Southern Pacific #7512 was originally a 3,600-horsepower SD45 that was built by the Electro-Motive Division of General Motors in April 1967 as Southern Pacific #8903. On June 29, 1984, it was upgraded at Southern Pacific's Sacramento Shops to an SD45R and was renumbered to Southern Pacific #7512.

The train's third locomotive was Union Pacific #3258, a 3,000-horsepower SD40-2 that was built by the Electro-Motive Division of General Motors in June 1974. In April 1976, it was converted for 80-mph high-speed freight service, becoming Union Pacific SD40-2H #8018. It was converted back to a standard SD40-2 in April 1981 and regained its original number.

The train's trailing unit was Chicago & North Western #6860, a 3,000-horsepower SD40-2 that was built by the Electro-Motive Division of General Motors in April 1974. The Chicago & North Western was merged into the Union Pacific on April 24, 1995.

The next train was another freight, led by Southern Pacific #9810, a 4,000-horsepower SD70M that was built by the General Motors Locomotive Group in London, Ontario, in June 1994.

The second locomotive in the train was Union Pacific #3216, a 3,000-horsepower SD40-2 that was built by the Electro-Motive Division of General Motors in April 1973.

The third locomotive was Union Pacific #B4250, a 3,000-horsepower SD40-2 that was built by the Electro-Motive Division of General Motors in September 1978 as Missouri Pacific #3250. After the Missouri Pacific was merged into the Union Pacific in 1982, the locomotive became Union Pacific #4250 on July 13, 1988. On July 29, 1992, it was changed to trailing-unit-only service with the removal of cab signals, refrigerators, toilets, and cab seats, and was renumbered with the "B" prefix.

The fourth locomotive was Denver & Rio Grande Western #3098, a 3,000-horsepower GP40-2 that was built by the Electro-Motive Division of General Motors in April 1972. The Denver & Rio Grande Western had merged with the Southern Pacific in 1988, but Rio Grande locomotives were still rare in the Pacific Northwest.

The last locomotive in this train was Union Pacific #6329, a 3,800-horsepower SD60M that was built by the General Motors Locomotive Group in London, Ontario, in September 1992.

Next came a four-unit helper set. The lead locomotive, Southern Pacific #8676, was originally a 3,600-horsepower SD45 that was built by the Electro-Motive Division of General Motors in October 1968 as Seaboard Coast Line #2023. After SCL was merged into CSX it became CSX #8923. It was retired and sold to VMV Enterprises in Paducah, Kentucky, where it became VMV #8923. In 1993, Southern Pacific contracted with MK Rail Corporation for 133 rebuilt 3,000-horsepower SD40M-2 locomotives. This locomotive was acquired by MK Rail and was rebuilt at its locomotive shop in Mountain Top, Pennsylvania, and was released on November 11, 1994, as Southern Pacific SD40M-2 #8676.

At the other end of the helper set was Southern Pacific #8283, a 3,000-horsepower SD40T-2 that was built by the Electro-Motive Division of General Motors in June 1980.

The last train we saw was a freight train led by Union Pacific #6188, a 3,800-horsepower SD60M that was built by the General Motors Locomotive Group in London, Ontario, in June 1989.

The trailing unit in this train's consist was Union Pacific #6154, a 3,800-horsepower SD60M that was built by the General Motors Locomotive Group in London, Ontario, in May 1989.
