The invention relates to a drive and brake system of a rail vehicle or a combination of rail vehicles, comprising a traction drive (1) for driving and for generative braking, at least one permanent-field synchronous motor (6) and a traction current converter (4) being associated with at least one axle of the rail vehicle or combination of rail vehicles. The traction current converter (4) comprises at least one pulse current converter (22) on the engine side, and the clamps of the permanent-field synchronous motor (6) are connected to a change-over switch (30) such that the permanent-field synchronous motor (6) can be connected to a load circuit (32) containing at least one load element (28), in order to drive the pulse current converter (22) or for generative braking. The aim of the invention is to be able to also activate or deactivate at least one friction brake (36) during the generative braking process according to the value of the rotational speed (n) of the permanently-field synchronous motor (6) and/or according to the value of at least one variable (U, I) based on said rotational speed (n).
