Very cool vid!

All of that to keep the 1.0 percent grade...

I expected more engines for a train that long that is being puller/pushed through 1.5 x 360 degree turns

1.0% grade, multiplied by tonnage over years vs alternative route.

How many cars were there? what do you mean about 1° grade?

A good read.the actual slope is an average of 2.2%. However, I want to point out for any who are not aware of the differences between gradient elevation degrees and percent of grades. Which falls into another of those measuring confusions. 1% of slope is 2° of angle. A 45degree angle is 100 percent slope
This will to better understand

Thank you!! A engineering marvel!!
