I can't imagine why, but cancelled train links disappear a few minutes after the train would have run.
We have the last 2 weeks
here, and I have archives too. I'm not monitoring weekend trains ... I would have to set up every weekend specially with all the substitutions and I ain't got the time.
Looking back over 14 days ... (back to and including 4th July). 6 trains out of 100 cancelled (so 94% ran). 3 out of 20 commuter trains cancelled (so just 85% ran). These is worse than the average statistic for the first six months of this year ... haven't done the maths, but I would think around 97% of all services / 95% of peak services ran through that pariod.
FGW have been having infrastucture problems this evening, with Swindon to Parkway shut, and South Wales trains diverted via Gloucester or Chippenham. A detailed alteration plan was published, including some shortened workings. The Westbury - Swindon - Westbury service was NOT listed on that alteration plan.
