 :One does already. The template is called {{Korean subway}} and you can insert it and change the parameters like so: 

  {{Korean subway | 
   Name                 = Seoul Subway Line 5 | 
   Color                = #660099 | 
   Font color           = #FFFFFF | 
   Image                = Transfer-line5-seoul-subway.jpg | 
   Caption              = Transfer Sign | 
   Revised Romanization = Seoul Jihacheol Je-ohoseon | 
   McCune-Reischaucer   = Sŏul Chihach'ŏl Cheohosŏn | 
   Hangul               = 서울 지하철 제5호선 | 
   Hanja                = 서울地下鐵第五號線 | 
  }} 

  
 This example produces the template at Seoul Subway Line 5. Just leave out the parameter for image, caption etc. if required. Right now you still have to manually add a category, I'll work on a different version specifically for stations that auto-includes the category. I'll also see about making different ones for each line with the colours built in. Hope this helps!   "
