Very few people, even Germans, know of the Bahn (German railway) flat-rate deal. So, here is the idea.
You go and pay 379 Euro a month or 4,090 Euro for a year.....and you get a second-class card which entitles you to travel twenty-four hours a day....seven days a week.....fifty-two weeks of the year.....anywhere in Germany on the railway.
You don't mess around with tickets or stand there at the machine trying to figure out X, Y or Z. You have a card, and if the conductor stops you.....you show your card, and that's it.
You could stand up on a Monday morning....decide to travel from Frankfurt to Stuttgart.....spend two days there, then travel to Munich for a day, then return to Frankfurt by Friday, then on Saturday decide to travel to Hamburg. No cost other than the flat-rate you pay each month.
A normal guy would analyze this. With 379 Euro a month.....you'd typically spend half that amount for one full trip (round-trip) from Frankfurt to Berlin......on just one weekend. So you'd have to travel at least twice a month on long-extended trips via rail....to the point where this might make sense.
It's not for everyone, and you rarely hear the Bahn folks talk about how many people have such tickets. A first-class flat-rate? Yes, there is such a card for that too....roughly 40-percent more than the 2nd-class ticket.
If you were a reporter or writing articles over Germany....requiring continual travel throughout each month.....the ticket would make sense. For ninety-nine percent of society....no, it's not worth the cost.
