From the Open Rails Manual: 8.1.4 Derailment Coefficient
The derailment coefficient indicates the likelihood that a car or wagon will derail, and is the ratio of the lateral force to vertical force acting on the wagon. This concept was first proposed by Nadal.
The higher the coefficient the higher the risk that a derailment will occur. Most railway companies tend to operate at a coefficient value of less then 0.8 as this gives a desireable safety margin for the car.
The OR calculated derailment coefficient is displayed in the Force Information HuD. The coefficient value will change colour to indicate the likelihood of the car derailing.
White indicates normal operation, yellow provides a warning indication, whilst red indicates that derailment is extremely likely.
Open Rails uses some standard defaults that it uses to calculate the derailment coefficient, however if the modeler desires greater accuracy the following parameters can be added to the WAG file in the wagon section:
ORTSLengthBogieCentre - length between bogie centres.
ORTSLengthCarBody - Length between car ends (typically measured between the coupler pivot points).
ORTSLengthCouplerFace - length between coupler faces.
ORTSNumberAxles - number of axles on the car.
ORTSNumberBogies - number of bogies on the car.
ORTSRigidWheelBase - used for calculation of curve friction
ORTSWagonFrontalArea - used for calculation of wind resistance
