Frequently asked questions
Where does the X4 bus run?
25 buses are numbered X4, in Birmingham, Bristol, Oxford, Doncaster, Derry Londonderry, Northampton, Salisbury, Chester, Southampton, Lancaster, Luton, Scunthorpe and 12 more places. Each one is listed above by area, with its timetable, stops and live map.
Why are there so many different X4 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 X4, and 25 of them do. The X4 in Birmingham has no connection to the X4 in Bristol: different operator, different road, different timetable.
How do I find the right X4 bus timetable?
Find your part of the country in the list above and open the X4 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 X4 bus the same route in every town?
No. These are 25 unrelated services that happen to share a number, run by 21 different operators. Fares, timetables and accessibility differ on each one, so always open the specific X4 for your area.
What does the “X4” in the bus number mean?
A number starting with X is usually an express or longer-distance route: it skips stops, or runs further than the plain number. It is a convention operators choose to follow rather than a national rule, so check the specific X4 for your area in the list above. See our guide to what UK bus route numbers mean for the letters that are reliable and the ones that are not.
