Looks like someone has changed it to be correct.The full service was withdrawn on 13 December 2008, although there is still a 'Parliamentary train' initially, one train per day ran directly from Walsall to Wolverhampton on weekdays, leaving Walsall at 19:36, but this was replaced in the 19 May 2013 timetable by a Saturdays-only train from Wolverhampton to Walsall leaving Wolverhampton at 06:38.
