Frequently asked questions
Why are there so many different S4 buses?
Route numbers in the UK are chosen locally — by the operator, or by the local transport authority that tenders the service — not from any national list. Nothing stops two towns hundreds of miles apart both running a S4, and 8 of them do. The S4 in Clondalkin has no connection to the S4 in Sevenoaks: different operator, different road, different timetable.
How do I find the right S4 bus timetable?
Find your part of the country in the list above and open the S4 that starts or finishes near you — each one links to its full timetable, every stop, a live map and its fares. If you know the stop you'll be waiting at, searching for the stop name instead gives you the next departures from that exact stop, which is more reliable than any timetable.
Is the S4 bus the same route in every town?
No. These are 8 unrelated services that happen to share a number, run by 8 different operators. Fares, timetables and accessibility differ on each one, so always open the specific S4 for your area.
