Tilting trains and travelsickness

[Bletchleyite]

It can, a study suggested that it affects people also prone to sea sickness around 20%. It was in one of the better railway magazines, might still have the issue.

The issue with tilt is that what your eyes see out of the window (if you have one) doesn't correspond to what you're feeling. This does make some people ill, and reducing the effect of it is why Pendolino and Voyager tilt doesn't completely remove the feeling of "G force" unlike the APT.

FWIW I found initially that Coach A (only) made me queasy (I guess because the tilt doesn't predict off the coach in front) though I got used to it.

Yes and that's why the APT-P without slight modifications to the tilt caused significant nausea in many people.

Usually the worst ride as well I believe because of that fact that leading coach gives the tilt predictions to subsequent coaches.

The ill-fated APT press run had many of the passengers indulging themselves on the free alcoholic beverages, which almost certainly added to the queasiness!

Very true, but originally it tilted to 9 degrees and each car tilted separately and often very suddenly on receiving the tilt signal. The engineers altered it to tilt to only 8 degrees (same as the 390 Pendolinos) and modified the system so that every car after the first one received its instruction to tilt off the one in front, this helped to lessen the chance of nausea by allowing some of the tilt forces to be felt by the passenger instead of cancelling them out all together.
