And I thought that we were the leaders in bureaucracy
It has been the subject of considerable ridicule. Part of the problem is that the government in Berlin is trying to introduce a standard national ticket in a federal country with lots of decentralised state and local authorities, all of which already issue local railcards. Each authority has the right to issue the ticket, and each authority has its own system for issuing it.
It took a heck of a lot of negotiation to get this far, and it'll be a while before they get the bugs out of the system.
German local authorities also have a tendency to be slow to adopt new technology and display a strange liking for fax machines.
