Yes but none of it can be attributed to FGW▸ , at least we are still not constantly seeing "due to traincrew unavailiabilty" or "due to train fault".
I've tried toput this in perspective ...
Over the last 48 hours, 49 trains (that's 2% of services) have been short term cancelled, short run, or missed out stops. Reasons for all alterations notified (that includes shorter trains, extra stops and catering changes) are:
Reason given 'weather': 35
Reason given 'stock': 13
Reason given 'not_identified': 8
Reason given 'staff': 6
Reason given 'infrastructure': 4
I put "stock" and "staff" at FGW's door, "infrastructure" at Network Rail's and at times I think that some of the "weather" problems could be prevented if Network Rail had the infrastructure in a more suitable condition for our climate.

My conclusion / comment. Yes - FGW problems are much better thank goodness, but still there are issues. It remains a lot worse in some areas - the service I use has figures a lot worse than 98% ... and it's more often stock and staffing than weather. But even here it was getting better until last weekend. That's another story.
