wow that would be quite a trip, but some of those countries I  would not want to travel  thru, like Russia, China and even Nam.   Had a friend who always wanted to ride Trans Siberian RR similar route, but he never did it.

It would.  But the cheapest price quoted for the Moscow-Beijing leg alone is 650 Euro (if you want the two-bed and showers, 900), with the article itself saying the trip will be 1200 or higher.

I'd be highly interested in those Talgo sleepers.
