Looks like a great blog... although my french isn't great and google translate isn't helping much...
Here's a quick summary:
9000km from Moscow to Beijing - took 6 days.
The Provodnitsa is like a concierge who runs the carriage. She took one bathroom for herself so everyone else had to share the only other bathroom. She also took control of the only power point, so if you wanted to recharge your phone you had to buy something from her first or just bribe her to use it.
There are no showers so you have to wash using the hand basin in the toilet and there is always a queue.
At one point it was minus 23 degrees outside.
They had to wait 5 hours at the border to change the train wheels.
The Chinese took great pleasure in refusing entry to a few Russians.
