The National Express website has options for travel by Coach (2 hrs 20 mins), and train ( 1 hour).
Prices seem similar - is the train really an hour faster? Is there any advantage to catching a coach, such as comfort or convenience? And is the coach station in Swindon close to the train station?
Thanks - planning on booking my tickets shortly so I can advise my family in Highworth of when and where I'll arrive.
