Ignore the suggestion? Who am I going to believe, you or my lying eyes?
I print the photo and I take out a ruler. It is pretty straightforward to measure the tilt of the power car relative to the crossties. The word-on-the-street they tell me is that the power car doesn’t tilt. It is harder to see the tilt on the coaches. In fact, there is a picture out on the Web of one of the Advanced Passenger Train prototypes where the tilt on one of the coaches failed, and you really have to study the picture to see it out-of-line with the other coaches. On the other hand, there are features on the coaches, the rooftop blisters come to mind, that may allow judging the amount of tilt.
