Well now; there are a load of timetable changes coming up on September 3rd.
The first Bus people were the gang who showed some interest in GoTimetable, so maybe they might go for a deal.
Meanwhile one interesting NEW service starting with all the changes is from Stagecoach.
Timed to connect with the more popular flights, the service runs seven days a week. Here are the Monday to Saturday times from Sheffield.
there are fewer journeys on Sundays. It would appear that this is a commercial development and local bus watchers say that it will be run from Rawmarsh depot (Rotherham) and not from either of the Sheffield depots.
