The Troisdorf–Mülheim-Speldorf railway is the main axis for freight between Cologne and the Ruhr area in Germany and the Netherlands. It connects the marshalling yards of Duisburg-Wedau and Gremberg.
History
The track was opened on 18 November 1874 by the Rhenish Railway Company to connect its Ruhr line with the Right Rhine line. It runs parallel, but a few kilometres to the east of the Cologne–Duisburg trunk line opened by the Cologne-Minden Railway Company thirty years earlier, from which it hoped to draw traffic. Since the line bypasses the centre of the towns, soon after the nationalisation of both companies in 1879/1880 passenger operations were closed on parts of it. Except on a few short sections the line is now used exclusively for freight.
