Practical tips
The train is faster, but the bus saves a lot of money on this short route. Look at both side by side in the table and decide whether the time saved is really worth the extra cost for you.
In Cologne, the train station and the bus stop are different places, even if they are near each other. Read your e-ticket carefully before leaving, so you do not queue at the wrong platform or stop.
Bus fares are lowest when you book ahead, and popular departures can fill up at weekends. Reserve online in advance and keep your instant e-ticket on your phone, ready to show the driver.
If you continue to the Netherlands or Belgium after Aachen, leave a comfortable margin between arrival and your next departure. Delays happen, and a missed connection costs more than an earlier departure.
If you are making a day trip, aim for a return well before the last service of the evening. That way a late arrival or a full vehicle will not leave you stranded in Aachen overnight.
The journey experience
Cologne and Aachen sit close together on the western edge of Germany, so the choice is refreshingly simple: a fast train or a much cheaper bus. If you are travelling on a budget, the comparison table on this page shows duration and price side by side, so you can see at a glance which option fits your day.
The train leaves from Cologne main station, right beside the cathedral, and it is the quickest way to reach Aachen. It is comfortable, with luggage racks and room to move around, and it brings you into the heart of the city. The bus costs far less and takes noticeably longer, which suits you if your schedule is flexible and your wallet is tight. Both can be booked online, and an e-ticket on your phone is all you need.
Our advice: if time matters most, take the train; if price matters most, take the bus, because the saving is big. Always check the departure point printed on your ticket, since the train station and the bus stop are not the same place, even when they are close. Departures run regularly through the day, so you will not be stuck. From Aachen you can also continue towards the Netherlands or Belgium, so check the cross-border conditions on your ticket before you go.
