And doesn’t all this work on the basis that in the instance of a crash, the main force is head on ?
Numerous recent incidents involving points issues, SPADs or other derailments have put the side of the train in danger (and thus the sleeping necks).
Again not wanting to be flippant but there are dozens of scenarios where people are at hugely greater risk daily (unrestrained on longitudinal beds on tour buses, for example). To say it isn’t possible just doesn’t seem credible, and it feels like any piece of travel carries a varying level of risk.
For example of the minute numbers of rail travellers who die on trains, one would assume (though I don’t have the numbers), that those nearer the front end of the train are at a greater risk. Presumably front/rear facing carries different statistical risk. Presumably intercity or commuter does too. We all make travel choices largely disregarding those differing risks (probably because they are all relatively minuscule in likelihood). I fail to see how the statistically minute possibility of a fatal collision involving a UK Train, let alone one of the 75 Caledonian Sleeper carriages of the 16000 carriages nationally, let alone one of the tiny proportion of those which might have had a portion of longitudinal sleeping arrangement, is a valid reason to undermine a design choice which is implemented far more widely in far riskier circumstances daily (without significant consequences, it would seem).
Ultimately the spectacular increase in fares over the past few years, combined with new stock whose costs will presumably be recovered from the fare payer in one way or another, prices me off the sleeper onto day trains or airlines, which I find annoying as the sleeper is a far superior way to travel (IMHO).
If they can fill the trains at £400-500 for a return to London on a train (based on solo room fares for a selection of dates in the near future), good luck to them. In a time where public subsidy will be under increasing scrutiny, significant subsidy for a service principally used by the wealthy at the exclusion of the regular traveller will be a hard political sell. Personally I’d be sad to see it fold.
