Which trains can I use to travel with the super saver fare senior?

If you have a super saver fare ticket for senior citizens, you can only travel on the travel connection indicated on the ticket. Super saver fare tickets for senior citizens are available for ICE, IC/EC services within Germany. You can use local rail services (e.g. RE, RB, IRE and S-Bahn or non-DB trains) to get to/from a long-distance station if you include them in your booking. You are not restricted to travelling on a specific train when using local rail services. However, your journey must be completed by 10:00 the following day.
