Thanks for letting us know! They're doing a reconstruction there because they plan to offer direct trains from Montreux to Interlaken in the future, without a change in Zweisimmen. I did't know about the bus though. Anyway, you don't need reservations for either the bus or the train. For the train it's optional, for the bus not even possible I think. In any case you'll get a seat.
Have a great trip!
