That is a pretty neat video, the story tells about how the expressions on the train were added in a post processing step, but the story and the inspiration seem pretty genuine.
Similar project in 2010, with a better video camera and detailed description:

The child's connection to the train and bringing it to life through editing.
Great video and great father. I have an honest question though, what's the regulation for this kind of things? For example, what would have happened if the train in free fall had hurt someone?
Didn't watch the video.. was hoping for announced design/plan for mass-transit system to the ISS =(
You should - it's really heart-warming, and a clever piece of animation.
Why is imagination the most valuable commodity? This is why.
