I'm on my way to Czechia once again, but first a stop in Germany and Switzerland.
In the morning I'm taking my first train. Today I will do a circle from Hamburg to Bremen and Hanover, then back to Hamburg
The Wanne-Eickel–Hamburg railway is the shortest railway link between the Metropole Ruhr and the Hamburg Metropolitan Region and hence one of the most important railway lines in northwest Germany. The Route runs over the cities Münster (Westfalen), Osnabrück and Bremen.
It was built between 1870 and 1874 by the Cologne-Minden Railway Company (CME) based in Wanne-Eickel, and branched off their main (Cologne-)Deutz–Minden route as part of the Hamburg-Venlo railway. Today it is an electrified main line which has a minimum of two tracks throughout. Parts of the route are equipped with Linienzugbeeinflussung train control which enables speeds of up to 200 km/h to be attained.
Due to its constant use by goods and passenger trains rolling along the line, day and night, it has been given the nickname Rollbahn ("Rolling Line"). (wikipedia)
