North Korea

edit

From 2002 the Korean State Railway has received a number of BJ class locomotives second-hand from China. They are used mostly for heavy shunting and on local freight trains around P'yŏngyang.[2] At least 33 have been delivered, numbered in the 내연301 - 내연333 series (내연 = Naeyŏn, "internal combustion"); most are still painted in their original Chinese blue livery, but a few have been repainted into the standard North Korean scheme of light blue over dark green, and at least one, 내연310, is painted in a scheme identical to the Chinese green livery used on Chinese DF4 locomotives.
