Appreciate this is off-topic, but I have to travel daily on 195s (when they aren't broken, anyway!) on the Calder Valley, and they are atrocious units: I am not aware of a new unit that has worse ride quality anywhere in Europe in the last 20 years, and many have christened them "New Pacers" as the ride is arguably inferior to a class 14X. Add to that the cheap and nasty seats with generally damaged and stained fabric covers, jerky brakes, the absent window-seat alignment, the rattles and bangs that abound from seemingly every component, and the obtrusive and often wrong PIS and PA systems, and you end up with an experience that does not come close to that of a decent 158 (let alone a 170, which is a good unit). I'm amazed they were accepted in this state - but then, the TOC were under obvious pressure to do so.
I would happily travel on a 319/769 over one of these!
