From 02 Sept. service 21 will be operated by York Pullman.
Timings from Bishopthorpe will be 5 mins. later than at present, except for the 08:25.
The main change will be at the York end of the route; the 21 will no longer go via Stonebow to Foss Bank but will start/terminate on Piccadilly. This will inconvenience folk who have used this bus to reach the supermarkets, but hopefully the shorter route will make punctual running easier to achieve.

Bank Holiday Monday.
The First bus website is silent on the topic, but a journey timing search indicates that as usual on bank holidays the No. 11 will be replaced by our Sunday bus (service 500) and timetable.
