The European time table change takes place on December 9 – in Austria, some details of the 2019 timetable are still subject to change, but you can already check preliminary timetables for December 31 on http://fahrplan.oebb.at.
According to the timetable, on December 31 this year, direct high-speed trains will depart every two hours. Also taking into account (only slightly slower) train connections requiring a transfer in Salzburg, you have options to get from Munich to Vienna by train roughly every hour throughout the day.
In Vienna, public transport services will operate on a normal schedule, with additional (quite frequent) service during the night.
