Korail Class 4400

The 4400 series diesel locomotive (GT18B-M) is a diesel-electric switcher locomotive operated by the Korea Railroad Corporation (KOR). It was introduced for shunting purposes and to replace older SW8 and SW1000 (2000-4300 series) units, and also to haul medium/short-distance passenger or freight trains.
== Technical specifications ==
* When running in the forward direction, the driver's cabin is located at the back and the engine room is located at the front, so when forming a train for main line operation, the locomotives are formed in reverse to secure visibility.
So some people know that the reverse is the front.
* Color CCTV was installed to enable crew 4401 to operate .
* A total of 59 units were introduced, including units 4401 to 4443 and 4445 to 4460.
* Nos. 4459 and 4460 are painted with the Baekdudaegan Valley Train design.
The early types (No. 4401 to No. 4420) have new headlights like the 7100 to 7500 series units, while the mid and late types (No. 4421 to No. 4460) have horizontal lights like the 2100 series.
== Disposition ==
A total of 59 units were built between 2001 to 2004. As of 2023 , all 59 units remain in service. The number of units is 60, but the 4444 unit was not manufactured at all due to the oriental superstitious taboo of the four characters , so there are only 59 units.
