So someone reads it!
Sadly the timetables index page still carried the mistake well over 24 hours after the offending detailed information was removed!
On 9th May, Stagecoach will make a significant incision in the timetable of the once-proud link between Sheffield and Mansfield, service 53. (For the benefit of pedantic "hairies", the evening and Sunday variant, diverted in the Mosborough area, is numbered 53A.)
By mid 1969 the long-standing traditional service 3 between Sheffield and Mansfield was joined by a limited stop version, the X53.
From 9th May 2011 this service drops to 2 hourly, but, retains the existing 2 hourly frequency on Sundays. How does fbb obtain this information, some two months prior to the change? It comes, as ever, from the splendid Derbyshire County Council web site, which posted an advance warning of the chop about three weeks ago. The actual timetable had appeared by 10th March. Here just a bit of it:-
Derbyshire have published the revised service X52/252 as well, by the way.
