FIELD: transport.
SUBSTANCE: for descents (90, 100) in the form of descended cars, respectively groups of cars, rolling resistance data is determined on rail portion of gravity hump (10). In this method, rolling resistance of corresponding descent (90, 100) on the next rail portion of gravity hump (10) is predicted considering determined rolling resistance data, as well as reference rolling resistance data specific for corresponding rail portion.
EFFECT: better optimisation of gravity hump operation.
