Bonn–Cologne Railway Company

It runs in a wide arc through Roisdorf, Sechtem, Brühl and Kalscheuren to St. Pantaleon station in Cologne.

Construction of the new route, however, was delayed partly because Bonn University protested to the Prussian king Frederick William IV against the fragmentation of Poppelsdorfer Allee (avenue) on its land.

The king finally commissioned the landscape architect Peter Joseph Lenné to design of the intersection of the railway and Poppelsdorfer Allee.

On 18 October 1855 the line was completed via Bad Godesberg and Mehlem to Rolandswerth and on 21 January 1856 the entire 14 km long extension to Rolandseck was opened.

Forty years later with the Köln-Bonner Eisenbahnen (KBE) was established with a similar name (but with more modern spelling), but it was not related to the BCE.
