I'm researching buying tickets for the Berlin to Moscow train on the Paris to Moscow express. But I'm fumbling over the ticketing and terms used for cabins. We want to buy a compartment for 4 people. Although there are only two adults and a child travelling, we want to buy the extra ticket so we have the entire compartment.
Also, any tips or suggestions about buying the Belarus VISA so we can travel through the country enroute to Russia are appreciated, too.
Try this webpage: http://seat61.com/Russia.htm
It is designed for people starting in the UK, but it gives you all the info you asked for, prices, times, how to book and how to get the visas.
This whole website ( http://seat61.com ) is the best source of information on travelling by train in the internet (and that is not just my opinion).
