Traveling by the railroad is considered to be one of the safest way. But not when there is Choo Choo Charles on the loose. This game follows the original horror story about the evil train who is pursuing you around the country. You have your own train to ride and improve. There are plenty of ways to do it, from gathering materials scattered on your route and opening chests that you can find in very unexpected places to completing missions to earn money and buy all the needed upgrades. Good luck!
