Remember that weird friend you had who had this huge train set with his dad in the basement and wore jean overalls and conductors hats and blew wooden train whistles? Found him.  And yes I did the back research on this guy to make sure this was real.  He may be playing it up a little bit, but this guy is a legit train freak.   He has 4 videos on youtube and they are all trains.    Trains just do it for this guy.
