From Aachen Central Station

In Aachen the best way to reach any place of interest is by bus or by foot. The main shopping area, the Aachen Cathedral, and the RWTH are situated close beside each other. Thus it is easy to walk from one place to another. Inside the city you find a lot of old architecture, little restaurants and pubs to enjoy a good meal and the Aachen culture.

 

1. By Bus:

In front of Aachen Central station there is a bus stop from which you can take a bus to your location in Aachen. The bus lines 3 and 13 are those you will probably need. They have a capital letter (A or B) behind the number, which refers to the direction of rotation. As the traffic network in Aachen's city center is constructed in rings, it does not matter in which direction you ride, but it may be a matter of time. Nevertheless you may possibly have to take a bus from across the road after leaving Aachen Central station.

The time table with departures and a road map with the destinations can be found at the bus stop. Tickets can be bought from the driver. Further information concerning fares and bus routes under can be found here and here.

Here are some of the most important bus lines which will bring you to points of interest:

 

(1) Hochschule (bus stop in front of the main building of the RWTH)

Bus lines: 13A (~20 min), 13B (~10 min) (the stop is on the other side of the street outside Central station). They depart every 15 or 30 minutes (depending on the time of the day) and ride from 6.30 am to 7 pm (mon–fri), 10 am to 5 pm (sat).

 

(2) Ponttor (H.4 Pontwall) (bus stop on Pontstrasse – the main street where students go for lunch or dinner) Same bus lines as for Technische Hochschule, additionally 3 A (~15 min) rides every 15/30 minutes from 5.30 am to 11 pm (mon–sat), 9 am to 11 pm (sun).

 

(3) Elisenbrunnen (famous thermal spring of Aachen, right in the city center, situated next to the tourist information and close to the main shopping area) Bus lines: 11, 14, 21, 44 ... (~5 min).

 

2. By Taxi:

There is also a very reliable taxi service at Aachen Central station. Just walk out the front door and you will see the available service on the right side. Prices depend upon your destination in Aachen.
