Will i get island line for free if i have the version of the game you get by having TSW2020? I forget what its called but i was curious because i dont really have enough money to get Island line. If anyone knows lmk.
TS2020 is a completely different game (it is not even the same game engine). There is no version of IoW in Train Sim World 1, so what you are getting in TSW2 is a completely new add-on (not a preserved collection update). You will need to pay for it.
Perhaps stefanochiodi1 means "Long Island Rail Road". If you have it in TSW1 (aka TSW2020), then it should be available in TSW2.
