The A service serves the complementary parts of each radial, and both lines serves all stations on the central part between Ny Ellebjerg and Hellerup.

[1] Service E is the continuation of the "fast" steam trains that ran between Copenhagen and Hillerød since the late 19th century.

They acquired a service letter when they were replaced by S-trains in 1986.

Later the main characteristic of service E came to be serving the outer end of the Køge radial.

A new Ex line started in 1983 servicing the Køge radial.
