ORTS Adhesion?

[cgsmithmo]

Can I get an explanation on how to implement these numbers for a modern diesel locomotive? I have done a small amount of testing, but I can't see a huge difference in performance changing these numbers...

On another note, I have had grand results using .include files following a discussion at ET. I have broken them into the locomotive engines( EMD\710, GE\7FDL16 ) And like what I see! Putting the actual numbers in the .eng files does the trick! THANKS OR Team! Keep up the good work!

..........!

There is a very detailed explanation on pages 76-79 in the OR Manual. Have you read that?

Yes, I have...A few times. How are they computated for each vehicle?

"The “actual maximum” of the tractive force is based on the Curtius-Kniffler adhesion theory and can be adjusted by a following parameter of the ENG file: Wagon ( OR_adhesion ( Curtius_Kniffler ( A B C D ) ) ), where A, B, C are coefficients of Curtius-Kniffler, Kother or similar formula. By default, Curtius-Kniffler is used"

It goes on to say that D should always be 0.7...What about the others?
