Ax, K, A+

Until 2007, separate service designations were used for trains that reinforced the basic service on the Køge radial in high-traffic periods. This was in part because they had their own stopping patterns, and in part due to the then-current doctrine that a service letter such as A must not be used for more than exactly 3 trains an hour. The first supplementary service was the rush-hour Ax which started running when the first phase of the Køge radial opened in 1972. It was upgraded to the daytime K service in 1992 and quickly renamed to A+ in 1993.
