If there's one plastic substance in the world that has the ability to inspire instant child-like joy, it's Lego.

Australian YouTuber "TrainGuy 659" understands the simple pleasure that Lego can bring, and has dutifully shared a video of a ridiculously impressive Lego train set. Talk about sharing the love.

The masterpiece of engineering, energy and miniature engines has already racked up almost half a million views.

It's got everything: Lego, trains, an absolutely bangin' soundtrack, a cameo from a Christmas tree... What more could you possibly want?

Didn't know today was going to be the day you fell deeply in love with model trains, did you?
