Does anybody know how is the border check nowadays, if I enter Germany by train? I'll take a train from Salzburg Hbf to Munich Hauptbahnhof on april 5 (thursday) 10am, expected to arrive at 12:30pm. Is there a check before entering the train, or a stop and check at the border? (I'll be entering the Schengen área thru Madrid then flying to Vienna).

Btw, I'm peruvian, don't need a Schengen visa anymore; I've been in France and Italy in 2016 and didn't have any problem crossing both countries by plane, but I guess Austria and Germany could have additional checks.
