Hello :)
It's worth a try! I wanted to thank the person who was on the same S-Bahn yesterday (March 2, 2025, S8 around 17:42 from Marienplatz towards Herrsching). The young man (between 20 and 28 years) speaks English- not german, but if you know him or might know someone who does, he is welcome to get in touch. :)
