We fly in at 1625. There are trains from the airport terminal to Salzburg at 1823 (arr 2044), 1844 (arr 2100) and 1923 (arr 2142). The earlier, the better so we can deposit our luggage in Salzburg, then catch the NightJet at 2201.
I'm guessing that the last train out of Munich is cutting it too close to make the connection (19 minutes).
But, are the others too early? I'm not familiar with the Munich airport, how long it takes to clear customs, get luggage and get to the train station.
Thanks!
