The game ends one turn after a player hits 2 or less remaining trains and this turned out to add a lot of tension in the last few rounds. Whenever one of my competitors drew cards instead of placing trains it was a huge relief as I was working on one last ticket. In the end I didn't make it as the game ended while I was still missing the Moskva-Smolensk connection to complete the Rostow-Smolensk ticket.
Final scoring for tickets easily doubles player scores, with huge swings for incomplete tickets. We had one player with an incomplete 21-point ticket, giving him a massive penalty without which he would have undoubtedly won the game. This means that while players can have a points lead throughout the game the winner is never obvious and tension remains high. Finals scores were 108-106-100-95 so it was a fairly tight distribution.
Overall this is an enjoyable and approachable game that I'd recommend for casual gamers. We'll almost certainly play it again and it will be interesting to see if the game holds up to repeat play.
