If a station name consists solely of the town/city name, I'm always going to assume it's the 'main' station for that settlement with the best connections to other services and modes and access to the main commercial area, whether or not there are other stations nearby with the town name prefixed or suffixed by an additional geographic, locality, road name or other descriptor. I can't think of an example where this would not be the case. Hence 'Main', 'Central', 'General' etc are superfluous in my mind. More difficult for a stranger arriving in a particular town is when the 'main' station has an ambiguous qualifier, such as Bristol Temple Meads, Edinburgh Waverley etc. and there are other stations nearby also with the town name in it.
