Bahn Bonus Points Saemmeln


The Bahn currently has a Web-based game for you to win some of their loyalty points. It’s not a very exciting game, but you get up to 500 points which is half a free ride across the country. (You get the other half when signing up for their program.)

In order to get these 500 points you need to play for an hour or so. Or you observe the Web traffic your browser generates and look closely. You’ll see that the Flash applet fetches a token from the server and sends your result, along with the token and some hash, to the server. How to get the correct hash you ask? Worry not, you will get the correct hash from the server if you don’t send the correct one. You can resend your request with the hash the server sent you and your POST will be accepted. Neat.

I don’t know why they send the “correct_hash”, but it’s obviously a bad idea.

Getting cheaper Bahn fares via external services

Imagine you want to go from some random place in Germany to the capital. Maybe because it is LinuxTag. We learned that you can try to apply international fares. In the case of Berlin, the Netzplan for Berlin indicates that several candidate train stations exist: Rzepin, Kostrzyn, or Szczecin. However, we’re not going to explore that now.

Instead, we have a look at other (third party) offers. Firstly, you can always get a Veranstaltungsticket. It’s a ticket rated at 99 EUR for a return trip. The flexible ticket costs 139 EUR and allows you to take any train, instead of fixed ones. Is that a good price? Let’s check the regular price for the route Karlsruhe ←→ Berlin.

The regular price is 142 EUR. Per leg. So the return trip would cost a whopping 284 EUR. Let’s assume you have a BahnCard 50. It costs 255 EUR and before you get it, you better do the math whether it’s worth it. Anyway, if you have that card, the price halves and we have to pay 71 EUR for a leg or 142 for the return trip. That ticket is fully flexible, so any train can be taken. The equivalent Veranstaltungsticket costs 139, so a saving of 3 EUR, or 2%.

Where to get that Veranstaltungsticket you ask? Well, turns out, LinuxTag offered it, itself. You call the phone number of the Bahn and state your “code”. In the LinuxTag case it was “STATION Berlin”. It probably restricts your destination options to Berlin. More general codes are easily found on the Web. Try “Finanz Informatik”,
“TMF”, or “DOAG”.

I don’t expect you to be impressed by saving 2%. Another option is to use bus search engines, such as,, or You need to be a bit lucky though as only a few of those tickets are available. However, it’s worth a shot as they cost 29 EUR only.

That saves you 80% compared to the original 142 EUR, or 60% compared to the 71 EUR with the BC 50. That’s quite nice, already. But we can do better. There is the “Fernweh-Ticket” which is only available from LTUR. It costs 26 EUR and you need to poll their Web Interface every so often to get a chance to find a ticket. I intended to write a crawler, but I have not gotten around to do it yet…

With such a ticket you save almost 82% or 63% compared to the regular price. Sweet! Have I missed any offer that worth mentioning?

Applying international Bahn travel tricks to save money for tickets

Suppose you are sick of Tanzverbot and you want to go from Karlsruhe to Hamburg. As a proper German you’d think of the Bahn first, although Germany started to allow long distance travel by bus, which is cheap and surprisingly comfortable. My favourite bus search engine is

Anyway, you opted for the Bahn and you search a connection, the result is a one way travel for 40 Euro. Not too bad:

But maybe we can do better. If we travel from Switzerland, we can save a whopping 0.05 Euro!
Amazing, right? Basel SBB is the first station after the German border and it allows for international fares to be applied. Interestingly, special offers exist which apparently make the same travel, and a considerable chunk on top, cheaper.

But we can do better. Instead of travelling from Switzerland to Germany, we can travel from Germany to Denmark. To determine the first station after the German border, use the Netzplan for the IC routes and then check the local map, i.e. Schleswig Holstein. You will find Padborg as the first non German station. If you travel from Karlsruhe to Padborg, you save 17.5%:

Sometime you can save by taking a Global ticket, crossing two borders. This is, however, not the case for us:

In case you were wondering whether it’s the very same train and route all the time: Yes it is. Feel free to look up the CNL 472.

I hope you can use these tips to book a cheaper travel.
