What is the difference between a Russian and a Chinese train?

No material difference. Both trains are originally of German manufacture, and are almost identical in design. The staff are of course either Chinese or Russian. The Chinese train makes the journey faster, passing through Mongolia. The Russian train goes around Mongolia via Manchuria. Both end up in Beijing. Train No. 2 runs from Moscow to Vladivostok. The English language skills of the staff are limited on all trains on the Siberian line.
