Subway

One line, Daejeon Subway Line 1, of a planned five-line subway system has been operating since 17 April 2007 (partial operations on this line began on 16 March 2006). This subway line connects Daejeon Station, located in the original city center, with the more modern and more recently developed sections of this city, including Dunsan, where the city hall and a number of national government buildings are located.

Notable differences between the Daejeon subway and the Seoul subway include narrower cars, no doors connecting cars, four cars per train rather than ten, and storage space under the seats for use by passengers. Originally, plastic tokens for toll were read by a proximity sensor when entering the turnstiles, and then inserted into a slot when exiting. The design of the tokens allowed them to be used for advertising. The system now employs the T-money system, a rechargeable series of Smart cards and other "smart" devices used for paying transportation fares. Platform screen doors are installed in the subway stations.
