Cologne Hauptbahnhof is one of the hubs of European long-distance traffic. Long-distance lines run on both sides of the Rhine via Cologne. Therefore, the station situated on the left (western) bank of the Rhine is connected to
Köln Messe/Deutz station situated on the right (eastern) bank of the Rhine via the Hohenzollern Bridge. Long-distance trains connect in the station from the
Ruhr region, southern Germany, Switzerland, the Netherlands and Belgium.
Köln Messe/Deutz (tief) station is used by two ICE services on the right bank route. In the past, therefore, a direct connection, such as a
moving walkway over the Rhine was considered, but this controversial idea was rejected as too expensive for the time being. The Cologne rail node is at the centre of eleven routes radiating in all directions. More than 280,000 arriving and departing passengers are estimated to use 1,200 trains daily. Cologne Hauptbahnhof, together with the Hohenzollern Bridge is a key bottleneck for rail transport in the Cologne region. Long-distance traffic load is concentrated to and from the east of the station, while regional trains mainly run to and from the west. The connecting lines from
Hürth-Kalscheuren and
Steinstraße are operating at capacity. Adding extra tracks is hardly possible. Changing the track layout is not possible with the existing signalling. The network will become increasingly congested up to 2030 and beyond. Although its platforms are divided into three sections each, they are still remarkably crowded throughout the day, and a major extension of the station is impossible because of its historic surroundings. Connections to the local Cologne network
Stadtbahn are made by two subterranean stations,
Dom/Hbf and
Breslauer Platz/Hbf at the respective ends of the station. The station has 11
main line passenger track platforms, of which two are used for
S-Bahn services; one of the two subterranean
Stadtbahn has two tracks with side platforms (
Dom/Hbf) the other (
Breslauer Platz/Hbf) has two out of three tracks in service and one side platform and an island platform (both in use). Its
IATA code is

Intercity Express and
Intercity lines, mostly serving Cologne every hour or every two hours: Various high-speed services connect most cities in Germany as well as several neighbouring countries in a few hours.
Eurostar high-speed trains run from Cologne to
Paris via
Aachen,
Liege and

Frankfurt. With a combined 403 scheduled long-distance arrivals and departures each day at Cologne in the summer timetable of 1989, it was the most important node in the network of
Deutsche Bundesbahn. With 383 scheduled long-distance arrivals and departures, in Deutsche Bahn's timetable of summer 1996, it was the second most important node (after
Hannover Hauptbahnhof).

S-Bahn trains Köln Hauptbahnhof is integrated in the
Cologne S-Bahn network. From Monday to Friday S-Bahn trains run at 20-minute intervals during the day and at other times usually every 30 minutes. Northwest of the Cologne Hauptbahnhof S-Bahn station is the
Köln Hansaring S-Bahn station and to the east is the
Köln Messe/Deutz S-Bahn station. All S-Bahn services serving the station, use these two stations. In the 2026 timetable, the following S-Bahn services stop at the station:
Local services Below Cologne Hauptbahnhof there are two stations of the
Cologne Stadtbahn. Stadtbahn stations
Dom/Hauptbahnhof station and
Breslauer Platz/Hauptbahnhof station are on the same tunnel that runs under the main station making a turn of 120 degrees. The former one is located below the southern end, next to the cathedral, the latter at the northern end where it connects to the bus station.
Breslauer Platz/Hauptbahnhof station was relocated and completely redesigned up December 2011. Line 5 has been rerouted from
Dom/Hauptbahnhof to
Rathaus station to connect with the first open part of the north-south Stadtbahn tunnel, which is currently under construction. One year later line 5 was lengthened one station from Rathaus to Heumarkt. Formerly, all trains stopped at
Dom/Hbf and
Breslauer Platz/Hbf, but, as the junction for the new line will be between these stations, line 5 trains only stop at
Dom/Hbf, and line 16 trains will only stop at
Breslauer Platz/Hbf when the line is opened. Currently
Dom/Hbf station is served by the following lines (during the day at ten-minute intervals, line 18 at five-minute intervals), but
Breslauer Platz/Hbf station is served only by lines 16 and 18: Services are offered by the
Cologne Stadtbahn and the
Bonn Stadtbahn, often referred to as
Stadtbahn Rhein-Sieg after the
Verkehrsverbund Rhein-Sieg (VRS - Rhein-Sieg Transit Authority). ==Future==
