Mystery switcher #2111 at NRE Shops, Mount Vernon, IL

Ok, I've searched the web and haven't been able to pull up any information on this old switcher that is used at the National Railway Equipment shops in Mount Vernon, Illinois.

It is numbered 2111 and has what appears to be Korean or Chinese writing on the side of the engine. 

Can anyone provide me with any information on this interesting unit?

KORAIL switcher #2111 at NRE Shops, Mount Vernon, IL

A old KORAL Switcher 2111 sits at the back gate to the National Railway Equipment shops in Mount Vernon, Illinois and is used to move equipment around. Although it’s seen better days, it still does it’s job!

According to Wikipedia: “The Korea Railroad Corporation, branded as KORAIL, is the national railway operator in South Korea. Currently, KORAIL is a public corporation, managed by Ministry of Land, Infrastructure and Transportation.

KORAIL operates intercity/regional, commuter/metro and freight trains throughout South Korea, and has its headquarters in Daejeon.
Historically, the South Korean railway network was managed by the Railroad Administration Bureau of the Ministry of Transportation before 1963. On 1 September 1963, the bureau became an agency that was known as Korean National Railroad (KNR) in English. In the early 2000s, split and public corporatization of KNR was decided by the South Korean government, and in 2003, KNR adopted the current KORAIL logo in blue to prepare corporatization.

On 1 January 2005, KNR was split into Korea Railroad Corporation (KORAIL), which succeeded railway operation with the KORAIL logo and name, and Korea Rail Network Authority (KR), which succeeded maintaining tracks.”
