Excellent article and commments. In response to Archelaos Stavrianos, the money resources in the game is Gems to buy better buildings, wagons and engines. You can buy them as stated above, but, Trainstation has built in features so even non-payers can earn gems. You can then use them to get premium items or use them in other ways to enhance game play. The more you play, the more you earn. You get a special bonus each day you sign in and another if you go through portal and play mini-game. I have been playing for 3 years and achieved all the goals I want to so far (yes, that includes the 10,000,000 mail, I’ve probably sent twice that by now) and am still enjoying the game. I’m at level 314 and have friends in the 600+ levels.
