I'm a sucker for trains. I grew up one block from a switching yard, and my grampa had a toy train that ran under his Christmas tree.

That's why this video of a toy train venturing through and around a house is the coolest thing I've seen this week.

It must have been a huge project to construct a toy train track, complete with trestles and switches, that runs into every room of the house and through the yard, but in the end it was worth it.

With a GoPro camera attached to it, this engine rolls past cats, what appears to be a dog, a bigger dog (or even a wolf), and toy trains running in the opposite direction.

I got a kick out of it, and I hope you do too.

To be fair, it couldn't have gone THAT smoothly, and it didn't here's the FAIL video.
