From 5 January 2026 a new year round hourly bus service #HW1 will be introduced from Carlisle along the course of the wall to Brampton, then Lanercost, Birdoswald, Gilsland, Greenhead and terminating at the Roman Army Museum- https://www.cumberland.gov.uk/buses/service/HW1
For large parts of the route this is the first bus service in over 20 years, and the most frequent ever.
Ironically it is more frequent than the long standing service over the core, more touristed, section of the wall.
Also from Carlisle to Bowness on Solway a new Sunday service #93S started on 7 December (again the first in decades) and the weekday service 93 has been strengthened-

You will not find these timetables on any internet planner, such as Traveline.
These will be a big bonus to people walking the Cumberland section of the wall. Cumberland Council has no legal powers to extend these services east to Vindolanda and Housesteads (in Northumberland).
