Looking at this thread actually makes sad reading...
I have been a regular user of TPE and its predecesors since the early 1980s
Up until 2018 the service wasn't too bad, we had seen service improvements over the years, loco hauled stock replaced with a more frequent service run by Class 158s, which in turn were replaced by 185s. OK so more capacity was needed but taking the period from around 2010 - 2018 I could plan a journey with reasonable confidence that I would arrive on time or close to it most of the time, with overcrowding being the only real issue.
Fast forward 5 years from 2018, which is when things went wrong and have stayed wrong ever since, we now have the worst service within my memory, in spite of new rolling stock and no doubt higher subsidies (dont have specific figures, but overall rail subsidies have nearly doubled). Front line staff morale is at an all time low.
In any other industry a company offering the level of service TPE have offered would be bankrupt and wound up well before 5 years.
My view is that DfT, ORR, TPE, Unions all have contributed to this situation. None are blameless.
My own experience as a passenger is front line staff have tried to remain professional, but have been hamstrung by the decisions of those further up the food chain. This is backed by a couple of acquaintances who used to work for TPE, and several posters in this thread.
What I find more worrying is that no one can see a way out of the current mess, and if that message reaches the treasury I can see there being pressure to massively reduce support.
And the big question - How can something that used to work OK fail so miserably.
