8. Can I use a PLUSBUS ticket on days that I don't travel by train?

If you have a PLUSBUS day ticket, sorry no. You can only travel by bus on the date printed on the ticket, which will also be the day that you travel by train.

If you have a PLUSBUS season ticket, then yes, you can travel by bus on any day, at any time, until midnight on the date that the ticket expires (printed on the season ticket). You do not need to make a train journey in order to use your PLUSBUS season ticket to travel by bus.
