Destroying other players road vehicles, intentionally, with trains is one of the most abhorrent behaviors and NOT acceptable. There's not even the need of mention the rules you break. And there's no story to tell. It happened (your actions, as logs show) and in fact 3 days is a very short tempban. Hopefully, enough to you think on actions taken.
Therefore, I'll decline, for now, your unban request.
