I am aware that my post about my experience of being moved to an isolated village by my parents was pretty negative, @mountainsunsets - but that is because it was a very negative experience for me.
I firmly believe my parents chose to move to a village, and chose the house they bought, with little or no thought whatsoever for my sister and I. It fulfilled all their dreams, but took me away from my only good friend, and dumped me somewhere where I did not fit in at all, made almost no friends, and was bullied relentlessly. The few friends I did make all lived miles away, so I couldn't go and see them outside of school - I couldn't get to them via public transport, because of the scarcity of the services and because there's no way my parents would have paid for the fares, and even if dad and the car were at home, he wouldn't have driven me to see my friends or to collect me afterwards.
I was an indoorsy, bookish child, with no interest in or ability at sports, and I was moved to an area that had absolutely nothing for me to do. Basically I spent a lot of time reading, in my bedroom. I was isolated, bored and depressed.
Your town sounds very different - not least because of the public transport links to the nearest big towns.
It is very much about personality - as I said, my personality was in no way suited to the life of the village my parents moved to - which isn't the fault of the village, but is very much the fault of my parents, who didn't stop to think whether I would fit in, and enjoy living there - and who did the sum total of bugger all about it when I didn't fit in, and was bullied and getting more and more miserable and lonely.
I suspect if you asked my mum (dad passed on over 20 years ago), she would say we had an idyllic childhood, in our remote village - but she would be completely wrong. I think she's blanked out me telling her about the bullying, and even back then, I don't think she actually looked at me for long enough to see how unhappy I really was.
It can work, moving kids from an urban area to a rural one - I just think that, as the parents, you have to consider it carefully, and take your children's needs and personalities into account.
