You can't hate on the guy's passion for trains, but when this heritage 1953 EA engine lets off it's horn, this 'foamer' may have 'passioned' his pants.

Side note: I just learned that extreme train enthusiasts are called 'foamers'.

WOOHOO! AHH YEAH, listen to that bell...OH MY GOD! LISTEN TO THAT HORN! OH MY GAHAHAHD....THIS IS SPECIAL!
