Because international trains often contain passenger cars from different countries, and so it are very colorful trains. Who knows which international trains are to see in Russia and Ukraine (I prefer Ukraine, because I know that the Fastov-Kiev route and the LZ-PZZ route are used by some nighttrains. Another reason why I prefer Ukraine is that I have so many Ukrainian passenger locomotives, mainly of the types CHS4(z) and CHS8. And which types of passenger cars (including foreign versions) are used in that nighttrains? Pictures are welcome (of course
).
