I still don’t get it. I’ll use round numbers to keep it simple:
First scenario- no temporary rails. Rail trip on turn is 500 ft. A 2 wide trip is 10% further, so 550 ft. Stretch run is 500 feet for a total of 1000 ft traveled for rail horse, 1050 for 2 path.
2nd scenario - temp rails. Rail trip on turn is 600 ft. A 2 wide trip is 10% further, so 660 feet. Stretch is 400 feet for a total of 1000 ft for rail horse, 1060 for 2 path.
Scenario two is more beneficial for horse on the rail, relative to horses not on rail.
I’m not a math guy, so maybe i’m thinking about this incorrectly?
