Returning back to the ride issues for a moment - how as everyone's experiences of the LNER sets been lately? I travelled in Coach L of 801229 the other day and while the unit is an absolute flyer, above 100 MPH the (conventional bogie no less) ride quality was considerably jittery and noticed by a few of us passengers.

It's less about speed and more about specifics of the track. Most of the route is okay if not quite as good as the the mk4s, but York to Doncaster is horrible. The frustrating thing is that if anything it seems worse the better the track is

That is an interesting comment. I was told about 30 years ago that the Selby Diversion was laid to a different standard of track. In BR days there was a slightly different wheel profile for ECML vehicles to resolve a ride problem that resulted from this different standard (RD9 and not the standard P8 as applied to all other High Speed trains). I know IEPs have P8 profile but I am surprised if this issue still exists today. I wonder if it is because of the lightweight bogies.
I remember LNER's engineering team spent a lot of time and took great pride in optimising the bogies on different stock for the specifics of the east coast route. I do wonder if the one-size-fits-all Hitachi maintenance regime is such a good fit for the rather esoteric GB network.
