Ulan Bator - Pechino biglietti ferroviari

Maybe, the train staff should provide bed sheets cleaner. In general, the wagon was quite comfortable and the train arrived in Beijing on time.

The train was comfortable and the coach was nice as expected. All went perfect.

Of all trains from Moscow to Beijing this one was the least comfortable. Old train with no included meal, no airco but fan, not working power outlets only on hallway. Suddenly no toilet paper. Chinese crew that barely communicated. Seems the Chinese trains have a less good experience than the Russian ones. But I guess it is a lottery which train you get as all others were better in some way

Everything as expected

It really depends on what train you get. The first one from Irkutsk to Ulan Baatar war quite new and really good. The second to Beijing on the other hand was really old and a bit dirty. But still alright. I don't think that the company has any influence on the type of train - it's just luck or bad luck.
