Not First Great Western, unfortunately, but a few offers from neighbouring
TOCs▸ that may be of use/interest to forum members. The third one is rather specific however.....

Now, why can't
FGW▸ have made a similar summer offer? Not the third one, obviously. Not many humans called Paddington I'd wager!!
