Exactly. Their are very few services in the UK that would justify that sort of service, and I doubt this is one of them. They'd best bet they have enough financial backing to subsidise the service until they have enough passengers to turn a profit, or they'll go on limping like W&S did until an eventual bankruptcy - probably with much less public sadness than Wrexham And Shropshire. For the sake of the potential investors, I hope that this plan is dismissed by the government or whoever makes the decisions nowadays.If you are going 'super premium' then you need a route which has high passenger numbers (only a minority will be willing to pay extra) to fill the train and a long enough journey (people aren't going to be as willing to pay a premium if the journey is only 1 hr). Even then Caledonian Sleeper (and less so the Night Riviera) and needs subsidy.
