Hello, I would recommend you the S-Bahn Line S1 Leuchtenbergring to Munich Airport/Freising. The length of this route would be a bit more than 40km and would fit in your portfolio. Plus it covers an entire route! This is especially a bonus for everyone like me, who likes to drive in the timetable mode. What do you think? Best regards, Alex
The Munich S-Bahn would be great! I would prefer the S2 Erding-Peterhausen/Alto-Munster, the only reason being I used to live in Erding and used to commute from there every day, but I think it was the S6 then, Erding-Tutzing.
