As I noted above, you have another thread complaining about a TOC not warning you enough about heat related restrictions which causes you to be delayed. I dare say if you had been inconvenienced by strike action you’d be complaining about that instead, so a case in point of damned if you do damned if you don’t.
What? Not at all! For the third time, I'm not saying do not put any warnings about being potentially being delayed/cancelled and allow extra time. This is sensible. That is completely different to saying DO NOT TRAVEL!
It's a completely consistent point. Just like if there are going to be national speed restrictions because of heat, probably put a banner saying possible delays on national rail (and they normally do!). I'm not saying they should put Do not travel everywhere so people cannot possibly be delayed, 'cos they ain't travelling.
