Frequently asked questions
Where does the X21 bus run?
8 buses are numbered X21, in Birmingham, Newcastle upon Tyne, Norwich, Stratford-upon-Avon, Paisley, Bishop Auckland, Blackwood & Puxton. Each one is listed above by area, with its timetable, stops and live map.
Why are there so many different X21 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 X21, and 8 of them do. The X21 in Birmingham has no connection to the X21 in Newcastle upon Tyne: different operator, different road, different timetable.
How do I find the right X21 bus timetable?
Find your part of the country in the list above and open the X21 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 X21 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 X21 for your area.
What does the “X21” 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 X21 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.
