In the Swiss regular interval timetable, which was introduced in 1982 and has been further developed and expanded since then, trains running hourly meet every half hour, usually around minutes 00 and 30, so that between Kemptthal and Effretikon the train encounter of the two trains running in opposite directions on line IR 13 could be recorded as a snapshot at 9.30 AM. From the left is coming RABe 502 # 207 "Stadt Bern", running from Zürich via Zürich Airport-Winterthur-St.Gallen-St.Margrethen-Sargans to Chur. From the right RABe 502 # 211 "Liestal" as IR 3260 from Chur via St.Gallen to Zürich. Both trains are running estimated nearly track speed of 115 km/h (71,5 mph). In the background the houses of Grafstal and the Givaudan Kemptthal site.
