Frequently asked questions
Where does the 109d bus run?
2 buses are numbered 109d, in Dublin & Aldergrove. Each one is listed above by area, with its timetable, stops and live map.
Why are there so many different 109d 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 109d, and 2 of them do. The 109d in Dublin has no connection to the 109d in Aldergrove: different operator, different road, different timetable.
How do I find the right 109d bus timetable?
Find your part of the country in the list above and open the 109d 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 109d bus the same route in every town?
No. These are 2 unrelated services that happen to share a number, run by 2 different operators. Fares, timetables and accessibility differ on each one, so always open the specific 109d for your area.
What does the “109d” in the bus number mean?
A letter on the end usually marks a variant of the plain-numbered route — a different terminus or a peak-hour extension — and what it stands for is up to the operator. It is a convention operators choose to follow rather than a national rule, so check the specific 109d 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.
