Thanks 
One small note on scripts that actually “mess with”/“control” the trains (which most likely also spawn them in someway): Those scripts (which mine was actually one of tbh) will most likely cause MASSIVE issues with trains despawning, not appearing, our even cause multiple trains spawning (often these issues occur when multiple players are active on the server).
So please be careful when using such scripts… It’s a very technical story to explain why that happens, but it basically comes down to which player is the ‘host’/‘spawner’ of the trains, and if other players can’t “detect” your trains properly it can all go ‘haywire’ quickly.
Mine SHOULD not have that issue anymore now because it’s using the regular game trains. IF something happens now: Blame R* 
haha
