=== Cologne–Aachen high-speed line ===
{{Main|Cologne–Aachen high-speed railway}}
The Cologne–Aachen high-speed line is not a newly built railway line, but a project to upgrade the existing railway line which was opened in 1841 by the [[Rhenish Railway Company]].  The line inside Germany has a length of about 70 kilometres (43&nbsp;mi). The first 40&nbsp;km (25&nbsp;mi) from Cologne to [[Düren]] have been rebuilt. Since 2002 the line allows for speeds up to 250&nbsp;km/h (155&nbsp;mph). Separate tracks have been built parallel to the high-speed tracks for local [[Rhein-Ruhr S-Bahn|S-Bahn]] traffic. The remaining line from Düren to [[Aachen]] allows speeds up to 160&nbsp;km/h (100&nbsp;mph) with some slower sections.
