Hello I am kathis, I am new to this particular game. Had it on my wishlist for a long time, got it when Humble bundle was offering it. Few things I am not certain I understand. If I buy a DLC train / route, and the game updates to 2021, do I need to rebuy the dlc? or is that mine now and it will work with future versions? Does this game have Light rail trains? Or are they all trains that deal with heavy rails? (I ask because I couldn't find the SD-100 or SD-160 series Does the game have multiple routes that would in real life connect, and if so could you in theory connect them in a quick drive mode? (example if they release more Canadian pacific line, could I in theory connect them to drive the entire route?) Anyway I heard the community is nice, so I look forward to meeting you, in the meantime I need to learn how to drive these trains @.@, the academy was easy enough to wrap my head around, but when it came time for the campaign stuff, it was a different model of train, and I have very little understanding on how it worked, but that's probably on me, since I just learned about the manuals.
