Your daily reminder that we live in the future: trains can make train tracks.
No, seriously: check out this video of an RU 800S machine performing track renewal, you won't believe your eyes.
The machine chugs along, removing ties from existing railroad, and distributing fresh new track in its place! This is truly a marvel of modern engineering: a task like this in years past would have taken thousands upon thousands of man-hours to complete. Now, it just takes one of these trains and a relatively small crew. Fascinating, right?
