So we'll have aged pensioners flung around the cars, as I have seen previously on the main South as they try and access the buffet for their morning cuppa.
It's not a pretty picture to see an aged person land on a folded table and see it smashed all due to the G forces on some of those sharp curves taken at speed.
So making it a tilt train and going a little bit faster is going to make this go away? Modern suspension systems can solve this issue without needing to put a complicated tilt mechanism in. Some realignment would be welcome for sure.
sims, what Vinelander says shows the big problem that older and not so old passengers who would not have been pensioners as such have with walking through the the XPT carriages either to the toilets or buffet. When in their seats the carriages generally are fine and have no real hint of problems regarding the ride they are experiencing.
Walking through them is another matter though, few passengers no matter their age can walk through without balance problems and having to grab the seats to steady themselves, and its not a matter of high speed either, nor really the track itself. Problem also is the simple aspect there is no hand rail sections on the backrests to help the passengers in their walking through the carriages, the other aspect is most people are simply not capable of adjusting their walk to compensate themselves with the ride in the carriages.
My first trip in an XPT and walking through the carriages I found the ride terrible, thing was that I was able to adjust my walking style in order to get through without problems. The reason was that the type of swaying and movement was very much like working as a fireman on steam loco's, especially when firing them, the 36cl in particular was rough riding at speed, ok sitting down but when firing one was balanced with one leg/foot on the tender/fall plate and the other on the main cab floor which had the body going in different angles, the only real aspect to counter the problem was walk/work with bent knees and body very much in a flexible like state. Being used to that type of motion I was able to walk through an XPT without problems, however I also saved a few passengers not as old as I was from falling over, note the movement was very heavily sideways accentuated, and constant.
Up front in the driving cab it was worse as again the bogies were sprung very softly and hitting a hole in the road one could be bounced up and down badly.
Despite all the track upgrades since their introduction, the passenger ride comforts have gone nowhere, except perhaps downwards.
