If it were a journey, it would be a pleasant one. But this is work, in Russia, passenger train cars are in poor condition, you repair them all the time, there is no time for sleep and food.
I think it is still the reason that the country's territory is too big that leads to the inefficiency of the railroad trains, maybe one year, we in China may go to build high speed railroads for you guys, just like we build highways and bridges for Serbia.
