I have previously written and dont mean to annoy anybody but could someone please tell me about how to pass time on the trains

there are some variants. for example, you can sleep, you can read a book, you can look into the window, you can eat or drink something (but you should not be drunken, otherwise you can have problems with the police ).

fire up up the HOMM IV (great prices in Russia!) on your laptop. Helps kill the time for sure. You also will get a LOT of attention. Don't know, how many HOMM IV players are here, but it seem to extremely popular in East Europe.

In the worst case the provodn'ik can perhaps provide you with good olde chess and similar.

Don't worry, the time goes fast on the trains (sometimes faster than the train). I never got bored and it always happening something.
