Regarding the recent train racing drama in the Discord server, why not just create a separate server for these sorts of things? Humans are humans, it's in our nature to do dumb things for entertainment, and this way all the shenanigans could be contained in one place instead of being spread out over the 30 odd servers and causing problems for everyone.
I personally don't have much experience with multiplayer, but in other games I've often found myself in pretty much a sandbox setting where I just hopped on a random train and drove it around without much care for time tables so I could take my mind off things. Yes, it's not realistic, but it's fun and that's what matters to me.
