The model is here.
I would suggest that the model is run under different circumstances to develop an understanding of how slip works in this new variation.
Once you are happy with the testing of the model provided, feel free to try your own model.

Surely this will be good? I don't see the ORTSNumberAxles and ORTSNumberDriveAxles lines. Then these two rows are no longer needed to adjust the steam locomotives? The ORTSDriveWheelWeight line is also not needed after this? Or does it not matter what value is entered, because it does not affect anything? At least it doesn't affect adhesion.

I haven't delved into looking at configs like Laci - but - I did see slippage in your example and it looks quite a bit better - when I hit the sander it stopped slipping. You have some time to catch it before it runs away. Make sure you have the key to slam the Regulator closed - mapped to a joystick or handy. Nice work to both you and Ceasar.
Regards,
Scott
PS - you don't have to actually slam the regulator closed - simply backing off a bit will stop the slippage. All testing done on dry track. I like it. My much larger locomotive won't slip under the same test conditions.

Thanks for picking this up. It was a cut and paste of the ENG files, and demonstrates how easy it is for mistakes to creep in.
The old values would have worked (as they did), however better practice is to use the more recently defined values. I have uploaded a minor mode to the model to correct these values.

A lot of more modern locomotives had FoA > 4 which made them less likely to slip.
