Plenty of freight on the Munich bypass and onwards towards Austria (especially at the moment, given that the route via Passau is shut). And seems to be pretty frequent diesel hauled freight using the Simbach route (which is great along the single track sections towards Munich), much of which uses class 66s (well, they're actually class 77s). Bonus of some class 418-haulage on the Munich Muhldorf services (although most are modern class 245s). I also saw a Stadler class 159 (basically an even beefier class 99) when I was there in June
