Nameless Seems odd to have sold the Groupsave, then abandoned them, but still be selling them on line.
Obviously not all 30,000 were ever going to be travelling by train anyway just can't get my head round the railways not doing what they are supposed to be there for because 'it's not worth it'.
Not blaming you personally, appreciate you are just supplying some inside knowledge of the practicalities...
The railways stopped being a 'service' and became a 'business' as soon as they were privatised in the mid-90s.
I don't necessarily agree with it, but it's the way it is. It would cost FGW a lot more money to operate than they would get back, and so like any normal business they won't provide extra services.
I imagine nobody noticed that Reading were at Wembley until recently, hence the sudden withdrawal of Groupsave tickets. FWIW I am led to believe that any already purchased will be valid, but they should no longer be on sale (online or at stations).
