I don't think it is fair when people only post in here when there are issues though. If you scoured this thread without taking note of the dates posts were made, you would just think that there are issues daily because every post made is a seemingly a negative one but there are often large gaps between posts when there isn't much to moan about. I have no issue in people reporting on the negatives when they happen but ultimately, to provide a fair assessment, those people doing that should really be reporting back when things are running ok as well if they want to give such updates.
There are issues daily.
Over the past 2 weeks (6 diagrams per day out of 9 or 10 units that 'could' be available) have had 6,5,5,5,4,4, 4,5,4,4,3 starting the day, but not necessarily finishing the day. 769421 has worked 3 days since its first appearance in late July and failed every day. 769431 (one of the overhauled ones) has been missing for over a month.
Every replacement in the last two weeks has been a 2 car short-form (other than 1 today) with persistent severe over-crowding, particularly the units that work in/out of Manchester Oxford Road.
Whilst I appreciate that there are problems all over, I defy you to come up with a set of services that has had so many problems over the past 2 years or so with little seemingly management comment or intervention. The fact that reports aren't on here every day is probably because it would be so repetitive.
Edit:- looks like the 3 out today are reducing to 2 shortly with 769450 retreating to SP in a bit.............with plenty shuffling around and further cancellations later today.
