Do LU keep stats for the overall reliability of the service on a monthly basis?
Back before the resignalling and introduction of the S-stock, my journey to Victoria on the HC&C and District lines, which, under perfect circumstances would take ~30 mins, would frequently take nearly an hour, with long delays possible at various points, meaning a dash across Victoria to catch my train. (Although I only ever actually missed it once.)
It's recently realised that now, there are very few significant delays, and I often make the journey in ~ 35 minutes. I've even cut the time I allow to 50 minutes.
Obviously the whole point of resignalling and restocking was to improve reliability, but I am curious as whether there was a sudden improvement, or whether it has been happening gradually.
LU produce stats internally on a daily basis for percentage of timetabled service lost and the reasons why.
Example; District operated 95.8% of schedule yesterday, this was reduced due to staffing issues.
I believe that many of the mechanical issues that previously delayed services have now been abolished; signal bulbs failing mechanical trainstop problems signal lever in interlocking room getting stuck
Unfortunately points, either pneumatic or electrically operated could still fail to operate and this remains.
