I live in Stockholm. Dwells on the commuter rail system here -- formerly at Stockholm Central, now at the new (2017) Stockholm City underground commuter station -- are scheduled for 3 minutes and have been for decades. The commuter rail service here is a bit of a basket case, but that has nothing to do with through-running practices, which make the system much better than it otherwise would be.
