The Korail Class 200000 or TEC (Trunk-line Electric Car) is a type of electric multiple unit operated by Korail for the Nuriro services.

History

It was originally scheduled to deliver units in the summer of 2008 and start operation on 15 December of the same year with the extension of Line 1 of the Seoul Metropolitan Subway. Due to the financial crisis, the amount of foreign currency delivery more than doubled from the time of contract. The first train was delivered on 9 January 2009, and the trial operation began on 6 February. On 1 June 2009, the trains entered regular service .
