I wouldn't say that was necessarily the case, I worked at Royston BO for a couple of years in the early 80's and we had the highest number of first class season ticket holders on the route as well as standard, a chap came down from GN house to study the record cards and found that the majority of them lived in the Cambridge area and sent some a questionnaire. The results showed that passengers were more inclined to travel to Royston for the better service into KX (1 fast, 1 slow an hour minimum) than the service from Cambridge. And Cambridge had seen a huge percentage of it's regular commuter traffic drop off a cliff.
