The station is named after Appellhofplatz (English: Appeals court square) and lies in the Innenstadt district of Cologne.

Between the two parts of the station there is a triangular intersection, connecting the tunnels to Neumarkt, Friesenplatz and Dom/Hbf.

Only the crossing in the tunnel to Friesenplatz is grade-separated, while the two others are at-grade – conversely, the crossing to Friesenplatz is the least frequented with just 36 trains per hour, while the other two serve 60 and 48 trains per hour.

With the construction of the North-South Stadtbahn, line 16 will be rerouted to its own tunnel, resulting in only 36 and 48 trains using the crossings to Dom/Hbf and Neumarkt respectively, which will lead to fewer delays on this congested part of the network.
