Thought I'd have a nosey at the Scotrail diagrams in the wake of the QS tunnel closures. Found a few services from Glasgow to Perth/Dundee/Arbroath, which are apparently timed for 75mph sprinters. Class 156s from QS mainly run to West Highlands/Stirling/Alloa/Dunblane, and have not been seen regularly further North since 2005. When I follow some of the diagrams (by viewing station platorms that the previous diagramed terminated in order to track the unit, though this isn't always accurate) I found that the train diagrammed often jumps from sprinters to turbostars. For example an empty coaching stock service from Dundee to Perth would be diagramed as a 75mph 156, but the train scheduled to do a service from that same platform is diagrammed as a 90mph 158. RTT differentiate between 158s and 170s by their speeds, so a service diagrammed for a 170 would show up as a 100mph 158.
According to RTT, all services from QS LL to Perth/Dundee/Arbroath are diagramed as a 75mph sprinter apart from the Carnoustie stopper which is a 90mph 158. So, unless 156s are actually working these services, is it more or less a mistake on RTTs part as 156s would need Glasgow or Edinburgh guards to work?
