Trains on stamps, Part 4: Stamps from USSR, Czechoslovakia, Bulgaria, Maldives, Italy, German Democratic Republic, Federal Republic of Germany, Poland, Laos, Bhutan and Kampuchea/Cambodia.

Of all these countries represented on this stock book page, who shows the most modern trains?

Kampuchea, of course. 

Isn't Kampuchea the premier country for railway technology?

And Bhutan, a close second?

Can you spot the tramway, on this page?
