The 500 series locomotives are a group of diesel-electric and diesel-hydraulic locomotives bought either new or second-hand by the Korean State Railway from the Soviet Union and Russia. The series includes several types of locomotive, all numbered in the 내연5xx range. The exact assignment of running numbers is not known, nor is the total number of units imported - or even all the types included in this series. However, the following are known:

ТЭМ1 - Diesel-electric. Soviet-made derivative of the American ALCO RSD-1. Around 20 units imported in the early 1990s.^[1] 내연569 is operational in the Namp'o area.^[2]^{[page needed]}
ТЭМ2 - Diesel-electric. Further developmnet of the ТЭМ1. Number imported is not known, but at least two - 내연587 is operational in the P'yŏngyang area in a livery like the ТЭМ1s, and another has been seen painted in the North Korean standard light blue over dark green colours.
ТГМ3Б - Diesel-hydraulic. Eleven imported new from the USSR in 1972-73.^[3] Very similar to the SM15-class of the Polish State Railways.
ТГМ4 - Diesel-hydraulic. Two imported new in 1985.^[3]
ТГМ4Б^Л - Diesel-hydraulic. Two imported new in 1991.^[3]
ТГМ8Э - Diesel-hydraulic. Export version of ТГМ6, same as JŽ series 744. A total of nine were imported new - 4 in 1986 and 5 in 1990.^[3]
