This is a suggestion for both Train simulator 2019 and Train sim world but I didn't know where to put it. Please include an AI only versions of released trains in the base package. It could help with AI diversity on certain routes (for example we could have Amtrak trains on LIRR), allow scenario creators to use dlc trains as an AI without having to worry about people not having the dlc and it could also help mapmakers by allowing them to create services for trains without having to own them. There shuld be a settings option that will make the game only pick trains that you have in service mode for those who want to switch services. I got this idea from DCS world, where it works that way. Please tell me what you think about it.
