Hmm. Would you care to enlighten us?
Why else would you use them?
Odd wording, not everyone dislikes the train. You'll obviously find the majority of comments online are negative because if your journey was comfy or average, you won't feel the need to comment. The only true way to find out how disliked the trains are would be to walk down the length of a train asking each person their opinion, but then you need to factor in the trains destination and the time of travel i.e you'll never get a definitive answer.
I personally never spend money on trains and I don't 'use' trains just for their buffet, just like many other people.
People use the train to travel, it's not so complicated. Not everyone used the buffet on HSTs and not everyone will use the trolley on IETs, to many the only thing wrong with the trains will be their seats, to some the seats won't even matter. My mum particularly likes them actually because she thinks if they're hard they won't retains as much dirt (don't really know if that's logical thinking) and she also feels morally better being on a train actually using the wires above it (albeit with what's becoming a chronic problem to do so).
You only have to flick back through this thread to know although these trains aren't the most liked, there are still mixed opinions and yet you still get people claiming they're bad in every way and nobody likes them at least once a month.
