Agreed GG, much more intricate this week!
Mr Fautley must have been thinking of you especially today - with a Viaduct . . . (truncated, naturally!), the SD & LUR Railway for you to trace on your map under the stairs at GG Towers, Roman Fortlet, Signal Station, National Park and Waterfalls. A veritable full house - n'est ce pas?
Maybe I am wrong but I do have a sense of déjà vu, since I could have sworn that the 1879 disaster itself has been mentioned or at least referred to in a previous puzzle. I do hope that we are not going the way of TV with repeat broadcasts?
I would be quite happy to go halves with you on the Abu Dhabi trip if your name features in the winner's circle next Sunday!
