Hello there! Fairly new player of a-train games, and I'm loving it! It's a amazing simulation of train/company/city simulator! Unfortunally it's difficult to find many information about it's mechanics. For my question, I know the difference with passenger train (commuter?) and express passenger train. The first has a high rider capacity and a highest ridership plus a less cost to run. The last is the opposit, but faster. I would really like to know when to use one type over another? Anyone knows a website/forum with informations about it's mechanics?Thanks in advanced.
