...and he wrote that for example tickets bought in Slovakia for domestic trips inside Russia are even cheaper than in Russia itself.
I'm planning a trip from Budapest to Lvov on the "Tisza-Express" night train. If I try buying tickets for this trip in Slovakia instead of Budapest, can I expect a significantly lower price?
Is it even possible to buy a Budapest-Lvov ticket+place reservation from inside Slovakia?
I book a platzkart Chop-Lviv ticket online for the domestic Ukrainian train that leaves Chop around 23:00 and arrives in Lviv the next morning.
Earlier that day, I travel from Budapest to Chop though Záhony with regular Hungarian trains.
p.s. traveling few time via Chop we can say that it's not the best place to spend time in that region of Ukraine, so if you arrive early, it might make sense to think about going to Uzghorod or Mukachevo right away, those places have much more things to see and it is convenient since you can as well catch your 601/14 trains there, thus without need to come back to Chop
...this would be the perfect oppurtunity to visit Uzhhorod aswell. The earliest train from Budapest arrives at 12:58 in Chop, perfect time to catch the 13:18 elektrichka to Uzhhorod, provided there are no serious hangups at border control.
