First off - appreciate all the input...
:naughty:
Seems like we have two different opinions voiced...
1) My freight car physics might be messed up - and - that could very be... I believe I got them with Bob Bodoin with his "Plainsman" blessing... LOL - but - it wouldn't be the first time I've messed something up...
2) The other is the forces might be a bit out of whack on ORTS...
I have no way of knowing which is the case...
I did try upgrading the brakes to the Pro Cast Iron version included with Route Righter - and - same deal - 1% brake on a 2.4% grade is like throwing out a boat anchor...
These are the values I updated and my full WAG file is attached...

BrakeCylinderPressureForMaxBrakeBrakeForce( .50 ) seems a bit off as that value '.50' gets you full brake force with _any _ application.
Darn pesky decimal points! :rolleyes:
