The S2 service of the S-Bahn Rhein-Main system bearing the KBS (German scheduled railway route) number 645.2 is a railway connection between the small Taunus town Niedernhausen and Dietzenbach.

According to a news report issued by Hessenschau, the S2 is the least punctual of the system, with only 83% of trains leaving on time.^[1]
