Having lived in fareham for some years, JonathanB and Paperclip are correct that Swanwick is closer, however it is not as popular station as Fareham Central (depending on where you are coming from) If it requires a further change i would suggest going to Fareham and taxiing from there, up to you if its a morning one, if its afternoon session then you may have the time. good taxi company to call when you get here is Fareham on 01329 235 235, or 01329 282282.
Hope this helps
