Golden City & San Juan No. 4

Golden City & San Juan No. 4 is a 55-tonner center-cab type narrow gauge diesel locomotive built by General Electric (GE) in August 1955, originally for the Algoma Steel Railroad Company (original road number unknown). After its retirement from regular service, it was eventually sold in November 1993 to the East Broad Top Railroad (EBT) in Rockhill, PA to be used on their tourist excursion trains. It was later sold again in 2002 to the Durango & Silverton Narrow Gauge Railroad (D&SNG) in Durango, CO, following the 2002 Missionary Ridge wildfire, to be used on a few short excursion trains there.

In 2004, it was later sold once again to the Colorado Railroad Museum in Golden, CO where it has remained ever since. It is currently lettered for the Golden City & San Juan Railroad (GC&SJ). As of today, it is used to operate short excursion trains on the museum grounds and is currently one of four operable narrow gauge diesels at the Colorado Railroad Museum, one of which includes No. 7, another former Algoma Steel GE center-cab type diesel that was also previously used on the D&SNG from 2002 to 2021.

Trivia

• After its arrival at the Colorado Railroad Museum, it was originally painted in a black paint scheme until being repainted in 2019 to a Chicago, Burlington & Quincy Railroad (CB&Q) silver and black paint scheme.
