Between 1969 and 1971, General Electric built 40 of its twin-engineed 5,000 horsepower U50-C
models. All 40 of the U50-C's went to the Union Pacific, where they
operated until being scrapped during 1977-78.
The ALCO Models brass import HO-scale U50-C (D-134) is included in the company's 1st Edition
Catalog. Their model was constructed in Japan by KMT-Kumata.
To date, no plastic HO-scale model has been released, however one was in the planning stages.
A TYCO U50-C
was considered by the company sometime in the 1970s. A pre-production example exists that appears to made from Athearn's
U-boat tooling riding upon TYCO's unique six-axle trucks.
