You appear to be assuming here that the Chinese tourists that you mention have lots and lots of holiday entitlement given how long the journey will take by rail. If they can afford a holiday in Europe one suspects that they could also afford to fly.

I'm afraid the vast majority of the population of China still don't have two pennies to rub together, let alone have the means to travel beyond their own province.
... I've been to China a number of times. This is categorically and demonstrably false. I mean, the fact that they have a domestic tourist market multiples larger than any other country says it all.
I'm genuinely staggered by this statement. This isn't 1980.

I'll accept that there might be an occasional land cruise sleeper train the whole way, at fares set very much at the level of 'astronomical', and designed to compete with other cruises, land and sea. Such as the Indian Pacific.
But there will not be a regular overnight (or more accurately, over at least 2 nights) sleeper service designed to compete with air. It simply can't at any level.
Note that European railways have been busily closing down their sleeper services for the past decade, and they all lose pots of cash. The Caledonian sleepers are subsidised to the tune of thousands of pounds per train, and yet still more expensive than the plane. They would have been withdrawn years ago was it not that a fair proportion of the customers work just next to Westminster Bridge. There is simply no way that a sleeper that distance will be priced cheaper than the plane. Do the maths!
If they're running a service from Beijing to Moscow (that will have to be sleeper as it's 36 hours) it will make little difference in terms of attractiveness to carry on to the rest of Europe.
China has an enormous sleeper market, and a middle-class that's growing extremely fast. Talk of not being able to leave your own province and all of this rubbish may have been true 30 years ago (not you I know), but this is a market they're very much wanting to tap into. You can't look at this with Euopean spectacles on.
And yes, I am perfectly capable of doing the maths - what you're forgetting is that the market between Scotland and London is a wee bit smaller than that between China and Europe. One has a combined population of 17 million, the other in the order of 2.1 billion. Even if the comparison is a little fairer and you just talk about the cities involved, you're still forgetting that the culture is different (and you've still got a catchment area of around 100 million around both Beijing, Shanghai, Guangzhou and any other Chinese metropolis these would originate at - the cities involved at both ends plus the surrounding areas). I mean, how the hell do you think the Trans-Manchurian stays in business? I'm not taking about a 2tph service here!
