Port Erroll (Cruden Bay by its official name) was one of the first North Sea (back in those days the North Sea was known as German Ocean) oil towns, hence the trains, hotel and golf course for a game after working all day on the oil rigs.
The first rush of oil dried up and they lost revenue from North Sea Oil so using the facilities for the oil business they opened up the place for golfing holidays.
Someone should write a book on Cruden Bay and its contributions to the import of North Sea Oil, it has as much validity as the vampires stories.
