The Saebyŏl-class (Korean: 새별 Saebyŏl, "New Star") is a medium-duty diesel-hydraulic shunting locomotive built by the Kim Chong-t'ae Electric Locomotive Works for the Korean State Railway.

[1] The Saebyŏl-class locomotives have a centrecab body design, with a full-width cab offset from the centre towards the rear of the locomotive and external walkways along the engine compartment hoods, and are slightly larger than the Red Flag-class shunters.

[1] They are powered by a 249 kilowatts (334 hp) diesel engine with a hydrokinetic transmission, and have a Bo-Bo wheel arrangement.

[1] In practice this is not an issue, as the use of Chinese characters to write Korean is officially discouraged in the DPRK.

An unknown number of Saebyŏl-class diesel shunters have been converted to 3,000 V DC electric operation by the removal of the diesel engine and the addition of pantographs and other necessary equipment; this work was carried out at the Kim Chong-t'ae Works.
