what is it?
The Korail Class 311000, formerly identified as Korail Class 5000 or Korail Class 6000, is a commuter electric multiple unit train type in South Korea used on Seoul Subway Line 1. Class 311000 trains were manufactured and delivered between 1996 and 2006, and again from 2012 to 2014 to expand service on the Gyeongbu Line and the Gyeongwon Line, and to replace older trains (1st and 2nd batch Class 1000 trains). As numbering spots in the 311000 series run out, the newest Class 311000 trains have begun to sport numbers in the 312000 series.
