Rotational monitoring system of at least one axle for a railway vehicle or train, the rotation monitoring system of at least one axle being arranged for: - identifying at least one axle controlled by it having an estimated instantaneous linear speed lower than a predetermined instantaneous linear limit speed; - removing a braking force to one or more wheels of the axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed, by canceling a pressure to brake cylinders associated with said at least one axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed; the rotational monitoring system of at least one axle being characterized in that the cancellation of a pressure to brake cylinders associated with said at least one axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed is obtained by acting on an electro-pneumatic valve arranged to perform a Remote Release function associated with pneumatic circuits generating brake pressure for said brake cylinders and adapted to cancel a residual braking pressure; wherein the electro-pneumatic valve arranged to perform the Remote Release function is conditioned by a hardware timeout circuit (507, 511), or by a software timeout function, arranged to limit an excitation command of a solenoid associated with said electro-pneumatic valve for a predetermined continuous time. the rotation monitoring system of at least one axle being arranged for: - identifying at least one axle controlled by it having an estimated instantaneous linear speed lower than a predetermined instantaneous linear limit speed; - removing a braking force to one or more wheels of the axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed, by canceling a pressure to brake cylinders associated with said at least one axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed; - identifying at least one axle controlled by it having an estimated instantaneous linear speed lower than a predetermined instantaneous linear limit speed; - removing a braking force to one or more wheels of the axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed, by canceling a pressure to brake cylinders associated with said at least one axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed; the rotational monitoring system of at least one axle being characterized in that the cancellation of a pressure to brake cylinders associated with said at least one axle identified to have an estimated instantaneous linear speed lower than said predetermined instantaneous linear limit speed is obtained by acting on an electro-pneumatic valve arranged to perform a Remote Release function associated with pneumatic circuits generating brake pressure for said brake cylinders and adapted to cancel a residual braking pressure; wherein the electro-pneumatic valve arranged to perform the Remote Release function is conditioned by a hardware timeout circuit (507, 511), or by a software timeout function, arranged to limit an excitation command of a solenoid associated with said electro-pneumatic valve for a predetermined continuous time.
