STOAG tickets valid until March 2012

From January 1st, new prices will apply in the Rhein-Ruhr transport association. STOAG customers who still have old tickets have the choice: They can “take off” their old tickets or exchange them. The deadline for departure is three months. Single, quad, day or additional tickets can therefore be used until March 31, 2012. The "old" ZusatzTicket can be used both as a new ZusatzTicket1 and a ZusatzTicket2 during this three-month period. 

It is also possible to exchange tickets until December 31, 2014. Only the difference between the old and the new ticket has to be paid.
