This German Belgian train is self-sufficient enough that I'm starting to question everything I've done with my life. It's a train that doesn't need tracks laid out for it—because it lays them itself.

The P811-S Track Renewal Train just finished installing a line to Overpelt, Belgium in May. Presumably, to top this, its next project will be some sort of chunnel. [The Presurfer via Neatorama]
