Aachen's railway station, the Hauptbahnhof (Central Station), was constructed in 1841 at the Cologne-Aachen railway line and replaced in 1905, moving it significantly closer to the city centre. It serves main lines to Cologne, M�nchengladbach and Li�ge as well as branch lines to Heerlen, Alsdorf, Stolberg and Eschweiler. ICE high speed trains from Brussels via Cologne to Frankfurt am Main and Thalys trains from Paris to Cologne also stop at Aachen Central Station. Four RE lines and two RB lines connect Aachen with the Ruhrgebiet, M�nchengladbach, Li�ge, D�sseldorf and the Siegerland. The Euregiobahn, a regional railway system, reaches several minor cities in the Aachen region. There are four smaller stations in Aachen: Aachen West, Aachen Schanz, Aachen-Rothe Erde and Eilendorf. Only slower trains stop at these, but Aachen-West has developed enormous importance due to the expanding RWTH Aachen university.
Aachen is connected to the Autobahn A4 (West-East), A44 (North-South) and A544 (a smaller motorway from the A4 to the Europaplatz near the city centre). Due to the enormous amount of traffic at the Aachen road interchange, there is often serious traffic accumulation, which is why there are plans to expand the interchange in the coming years.
The nearest airports are D�sseldorf International Airport (80 km), Cologne Bonn Airport (90 km) and Maastricht Aachen Airport (40 km)
