I remember the first time I did that trip from London to Edinburgh by rail!
It was June 1999 and I had never been to England before. Adrienne had the good sense to get a 'Britrail' pass....and the stupid British rail people dud themselves!
We brought two Britrail passes which entitles us to use the British Rail services for 5 days over a one month period. So, there were our tickets with 5 boxes on each and the protocol was, as the conductor came around he should initial and date a box on each ticket to signify the service had been used on that day....but the silly buggers did not understand what these passes were, they would simply look at them, give them back to us and move on to the next! So we each managed to have 7 trips courtesy of Britrail and there was still 2 unchecked boxes when we left Britain, which daughter Sarah put to good use after we left to tour Europe and return to Oz....and I think one of those trips she did was also a London/Edinburgh!
Lizzie, I remember thinking how the first part of the trip I was diappointed, we travelled through countryside that looked just like home but oh how right you are, nearer the Scottish border that North Sea secenery was lovely. The next time we went up there some years later,I looked forward to it again and Lizzie the 'Cockle Train' section of the Steamranger trip from Goolwa to Victor Harbor is very remeniscent of that North Sea journey.
Ok....enough about trains....but hey, you started this!
Cheers......Rob
