Hej!
i am trying to gring to level 55. and i saw an achivement for 50k xp if i get 140 more unique disel trains, right now i have 106 and i need to get more. So the only way of getting new ones is by express trains, so i need whistles but i don't know how to get more without doing Contracts. Please tell me if there is any best way!
Thanks! -John
