Back in the day it used to be decker operated on a 20 min frequency in both directions (circular with 19) with an evening and Sunday service too. The route has changed, particularly in Grindon/Springwell (oddly abandoning the bit of Springwell Road where it was the only service, now just unused shelters outside the health centre etc), and the cut of the Durham Road/Kayll Road bit, as well as the Town/Grangetown/Leechmere/Tunstall limb which went years ago. Some of the changes happened way back when the old Service 6 was withdrawn and the 18/19 revised to replace it in part. Others more recent.
Never knew it was as frequent as that, mind can remember the loop. It's a shame that the BSIP couldn't work with it and do something useful with it tbh. Sort of route which could be actually be useful if it was maybe adjusted to serve different areas like Springwell Road you mentioned, know the stops, you're talking about.
