It may be one of the things Danes complain about most (after the weather), but an EU report on train traffic shows that Danes are using the train more and more and passenger traffic has grown by 15 percent since 2010, the biggest increase in Europe. 

Lithuania came in second, with a rise of 12 percent, and Luxembourg and the UK were right behind with an increase of 9 percent.

Wise to remove bike fee
Christian Linnelyst, the head of marketing at national rail service DSB told Politiken that the decision to discard bike tickets for S-trains was part of the reason for their success. 

"Since we made it free to bring bikes in S-trains, we have had a massive rise in passengers. More people also move to the city, where the train service is more varied."

Less personal service
Despite the international acclaim, DSB has faced criticism for making ticket purchases too complicated.

Soon DSB will only have four ticket offices left on the stations. Those are located in Copenhagen Airport, in Copenhagen Central Station, in Odense and in Aalborg. In all other places the ticket office has been replaced by ticket machines, digital solutions online and on mobile phones, along with the sale of tickets in 7/11 shops.

However, DSB's own customer surveys suggest that electronic ticket sales are becoming more publicly accepted.
