From 2006 to 2007, 204 third generation Series 313 cars were manufactured, continuing on and enhancing the concepts of "thorough efficiency" and "improved service" of the first and second generation Series 313 (manufactured from 1998 to 2000) as well as aiming for stepped-up "passenger service" in order to bolster competitiveness vis-a-vis other competitive means of transportation.
