The Škoda Type 22E2 type locomotive is a multipurpose electric locomotive built for the North Korean State Railway by the Škoda Works of Czechoslovakia.

[1] Although some lines had been electrified already in the colonial era, the large-scale electrification of North Korea's railways began in 1956 after the end of the Korean War and the subsequent reconstruction of North Korea's railway infrastructure.

[3] The Type 12E was developed by Škoda Works based on the technology of the BLS Class Ae 4/4 built by SLM Winterthur.

Current collection is via pantograph from overhead lines; the on-board electrical system is 48 V.[3] The total number of Type 22E2 locomotives ordered by the Korean State Railways is not known, but at least three are still in service as of October 2015.

[5][6] Some have been rebuilt in various ways, such as the addition of 'bumpers' on the ends and other features unique to individual units;[7] these have been renumbered (one such rebuilt locomotive carries the number plates of the Ch'ŏngnyŏnjŏl Kinyŏm-class "Pulg'ŭn'gi 4011"), but the unmodified examples continue to carry their original 전기50 series numbers.
