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 2008 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 .^[2]
