I knew the Scarborough York service would fail as soon as they went back to through working across the Pennines, at least with the shuttle it was more reliable.
What I dont get with Transpennine is that they must be aware that they will not have the resources to run the full timetable over a considerable period, this is not just the odd cancellation, its around half the service on some routes. In this situation an emergency timetable would be better, at least then you could plan a journey, the current 'will it run lottery' (because I dont count cancellation up to 10pm the night before as reasonable, given that most people are making plans a few days or weeks in advance) means that the train is currently unuseable on the TPE routes.
