Harrison: A train conductor

I have posted before about Harrison's adoration for trains.. especially the 'Red Nose Choo Choo.' As a reward for being good in church, we take Harrison to the train tracks after church on Sundays. This Sunday, the 'House' was open and the man let him inside. He was extremely brave.
He got to sit in the driver's seat.
Then before getting down, he got to stand and smile.
