Maybe because the service has been poor. I'm not a regular user any more but I used to catch the train a lot. Once it degraded I found driving more reliable. Also I often pass the station in Basingstoke and have seen lots of occasions in the last year when Bus Replacements are running at weekends. That isn't going to help. New house building in Basingstoke has also not happened much since the Franchise changed. That is likely to change in the next few years with what is almost a new town being built at Manydown. Unfortunately that is about as far as possible from the station.
