The GF6C was an electric locomotive for freight duties built by General Motors Diesel in collaboration with ASEA of Sweden.

Seven of these locomotives were built in 1983 and 1984, for use on the BC Rail's electrified Tumbler Ridge subdivision.

BC Rail chose electrification for the Tumbler Subdivision because the line had long, non-ventilated tunnels, as well as steep grades and sharp curves.

A combination of the declining coal market, and lack of coal being produced from the Quintette mine led to the electric system being shut down due to low traffic, and high maintenance costs.

6001 is currently preserved and in remarkable condition, and, according to the museum's curator and park manager, is still operable if provided with 50 kV of electricity.
