The Korail Class 8000 locomotive is a series of South Korean electric locomotives operated by Korail. This locomotive was introduced from 1972 to 1990, after electrification of several industrial lines. It was assigned both passenger and freight duty until the introduction of the 8200 series, which restricted the older locomotives to solely freight service. 94 were built (numbered 8001-8094), but many have been retired as new replacements enter service.

Retirement
As the Class 8000 locomotives neared the end of their 30-year lifespans, Korail found the need to order replacement locomotives. The replacements came to be known as the Korail 8500 locomotives, and have been steadily entering service since 2012. The majority of the Class 8000 locomotives have been retired by the new Class 8500 locomotives; only units 8091-8094 remain in service up to this day (from the entire order of 8001-8094). Units 8001 and 8091 are expected to be preserved at this time. They are currently stored out of service.References
