The Complete Union Pacific Tie Change. Hi-tech machines work in sequence to replace old and rotten railroad ties. This is a huge improvement over the old practice of doing it all by hand.
A correction:
After thinking about it for a while, the small bars at 23:00 were probably to keep the rail from sliding, not the ties. Think about a long, heavy freight train even slightly using the brakes to slow down. The momentum of all those freight cars with brakes on makes entire rail want to slide forward. Those tiny bars probably keep the rail from sliding along the ties, which are firmly embedded in the ballast.
