I would suspect that the passport checks will continue unless substantial progress is made to stem the flow of refugees through Austria in the next few weeks.

Depending on the type of ticket you purchased, you could either be asked to be rebooked on the local service (Meridian to the border, Westbahn from there), or detour north to Plattling, and catch the ICE service which crosses at Passau, which would probably be my preferred route. It will add an hour onto your journey, but the chance of significant delays is substantially reduced.
