It was a twice-weekly service that ran around the estates and helped Marple and High Lane residents who were not quite as able as some. There was one bus that was the 303 then the 305 in the morning and then the same in the afternoon. Tuesdays and Thursday if memory serves. When I was a cllr, with the help of Cllr
@ColinMac , a petition was raised and we did approach Stockport council and TfGM, but the low numbers and hard financial times meant it stopped a while back, unlike the subsidised 394 Glossop service that is still going Mon - Fri.
Surprisingly, Marple Station were given a whole load of bus timetables a few weeks back and the 303/304/305 service timetable was amongst them. Left hand... right hand....
