Description edit

Following the success of the Red Flag 6-class articulated locomotives, the Kim Chong-t'ae Electric Locomotive Works set to the development of a successor in the early 1990s. The new design integrated updated mechanical and electric components, allowing for a maximum speed of 120 km/h[1] with a power output of 5,418 kilowatts (7,266 hp).[2] They are essentially an upgraded, two-part version of the Ch'ŏngnyŏnjŏl Kinyom-class locomotives, which are a locally manufactured derivative of the Francorail-MTE CSE26-21-type diesel locomotives received by the Korean State Railway from France in the 1980s.[3]

The first two prototypes were numbered 7001 and 7002, and both were painted in different variations of a red and yellow livery. Misleadingly, 7001 wore "Red Flag 6" nameplates on the cab ends; 7002, however, carried new nameplates inscribed with the new designation, Red Flag 2.16 class, after the birthdate of Kim Jong-il.[1]

Aside from the two prototypes, locomotives of this class have not yet been noted on rail lines generally seen by foreigners, though two have been seen inside the Kim Chong-t'ae Works plant.[2] 7002 was on display at the Museum of the Three Revolutions in P'yŏngyang for a time,[1] but by the spring of 2007 it had been removed and put into service in the northern part of the country.[4]
