Stolberg is a town in North Rhine-Westphalia, Germany. It has a long history as an industrial town and belongs to the district Aachen and the lower district court of Eschweiler.

The Cologne–Aachen high-speed line is the German part of the Trans-European transport networks project high-speed line Paris–Brussels–Cologne. It 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. When it was continued into Belgium in 1843, it became the world's first international railway line.
