No Humping in Louisville? No Problem. We'll Just Use Flat-Track Switching

This is a video focusing on the CSX and NS yards in Louisville, Kentucky.
Both utilize flat-track switching instead of a hump.
We follow along as a few strings of cars are sorted.
The video has been sped up 4X.
I do have to ask how this can be more efficient than sending cars over a hump?
It just seems very time and labor intensive compared to what I've previously seen.
Also, this highlights just how dangerous this work can be. I believe there were 3 CSX crews sorting cars at once. Anyone not paying attention could easily get killed.
It is incredible the skill these crews have to sort cars like this.
I think they have good eyes too.
I think the NS crew noticed my drone around the 18:45 mark.
The 747 lands at the 23:07 mark.
I do hope you enjoy the video and will hit the like button and leave a comment.
I've got a trip to Chicago showcasing the Amtrak facility there coming out soon.
Until our next trip, I hope you have a great day.
