Train run by doorbell?

Has anyone ever made a train that runs when someone rings the doorbell? I want to make one that would run around the room, suspended just below the ceiling. My grandson was telling me about one he saw in a movie and said we need to make one.

Thanks for your input

$10 in eBay parts didn't sound expensive to me, where is the expense? You don't need to install home automation to do a simple task like this.
Yes, a door-bell button, a relay or two, and some wire, and the "automation" is all done.
