Thanks to those who responded to my earlier question.
I've got a feeling the 2014 review might have been when Service 3 replaced Service 20 and that Autumn 2015 was when the Leighton Hospital extension got withdrawn.
I didn't know that First Potteries had ever operated the 38 Crewe to Macclesfield route.
If you're referring to my list, that'll be the 38 to Birches Head, not the Cheshire variety.
Yes, the 20 became the 3 as part of the 2014 review.
6 September 2015 was when the Leighton Hospital extension was withdrawn, along with the Madeley extension (from Keele) at the other end of the route.
10 January 2016 the 3 became Hanley to Crewe.
15 April 2018 is the first showing the 3A.
Covid reductions (excluding withdrawals)
Service 6/6A remains every 15 minutes instead of every 10 (4 buses saved). That was reduced for the school holidays in summer 2021, goodness don't the kids get long holidays nowadays!
Service 8 reduced to hourly (1 bus saved)
Service 18, as mentioned (2 buses saved).
21/23 reduced to every 30 minutes each from every 20 minutes (3 buses saved).
Service 25 is currently every 12 minutes (15 in vacations) instead of every 10 (2 buses saved).
Service 3 does not have a timing point at Haslington for the timetable commencing 22 July 2014 (the network review date). It does have one for the preceding 20 timetable (6 October 2013) and for the 3 timetable revision dated 30 November 2014.
