From 2nd August, Hilperton, as you probably now know, will only be served by service X34 - see www.faresaver.co.uk/timetables/558d7bd93f10c.pdf for the timetable.
Please note that this is a commercial service which does not receive any subsidy from Wiltshire Council. If it doesn't make a profit, it will be withdrawn,
So, as ever, the mantra must be USE IT OR LOSE IT.
