It's not difficult at all to avoid being 'caught' in first class.
First class is marked first class and pretty damn obvious (compared to other stock and how bad some trains have been marked in years gone by).
So you get on and assume it IS first class unless you've checked the timetable OR seen the platform screens saying it's at the front of the train only. Or asked staff. Or maybe even posted on here!
The only exception was/is when weekend 700s are replaced with 387s and the screens still say 'front of train' which is misleading, although maybe now fixed and hopefully a temporary issue as 700s should be used on weekends anyway. In that case, I'd expect an appeal to succeed, or for revenue officers to show discretion in the first place.
I really don't know what more needs to be done. Just assume it's first class, as marked, until you know for sure otherwise. You can't mess up then. It's not as if anyone HAS to be in first class - there's 7 and a half, or 11 and a half, coaches available. Even on the trains where it's declassified both ends, that's still a tiny part of the overall train.
Ok fair enough
But why not follow the correct procedure and give me a ticket eith the 21 days to pay instead of being a jobs worth and going straight for the mg11
Guess thry have to make up the compensation some how
