A monitoring system for at least one plurality of homogeneous devices is described, wherein a first portion of the homogeneous devices is arranged to be installed in a first convoy and a second portion of the homogeneous devices is arranged to be installed in a second convoy. A functional state of each device is represented by a respective value of at least one operational quantity common to the plurality of homogenous devices. The monitoring system comprises first communication means arranged to allow the transmission of a first plurality of values and a second plurality of values, at least one first diagnostic means arranged to detect an operational fault or a maintenance request from the at least one device that is installed in the first convoy, and at least one second diagnostic means included in the second convoy arranged to detect an operational fault or a maintenance request from the at least one device that is installed in the second convoy.

A system for determining an adhesion value between wheel and rail for a railway vehicle is described, comprising an optical information acquisition means arranged to acquire optical information from the rail, a database arranged to store the acquired optical information in at least a learning phase and to associate said information with a relevant real wheel-rail adhesion value measured at the moment of acquisition of the optical information, a control unit arranged to determine the current wheel-rail adhesion value on the basis of a comparison between current acquired optical information and the optical information previously stored in the database. The control unit determines that the current wheel-rail adhesion value associated with the current acquired optical information corresponds to the adhesion value associated with the optical information stored in the database having the highest degree of similarity with the current acquired optical information.

A device and method for dispensing a friction-coefficient-optimizing mixture of at least one lubricant and at least one grit into the gap between a rail wheel of a rail vehicle and a rail. The device includes a reservoir for the lubricant, a reservoir for the grit, a metering unit for metering the lubricant, a metering unit for metering the grit, a delivery apparatus for delivering the lubricant, a delivery apparatus for delivering the grit, and a common dispensing nozzle. The apparatus for delivering the lubricant and the apparatus for delivering the grit are separate from each other and end in the common dispensing nozzle, the friction-coefficient-optimizing mixture therefore not being formed until the dispensing, and an additional compressed air line is provided, which ends in the common dispensing nozzle.

A method is described for detecting a braking action of a railway vehicle (RV) comprising monitoring the load transfer to a first axle of the railway vehicle (RV) from a second axle following the first axle according to the direction of travel (d) and, if the load transfer exceeds a predetermined threshold, determining that the railway vehicle (RV) is braking. An emergency braking method is also described comprising detecting an emergency braking request, activating an electrodynamic braking system to decelerate the railway vehicle when the emergency braking request is detected, applying the method to detect a braking action of a railway vehicle and, if so, determining that the electrodynamic braking system is operating correctly and using the electrodynamic braking system to fulfill at least partially the emergency braking request.

A braking control system includes braking control modules configured to generate a braking torque request signal, indicative of a requested braking torque value CFr, which is variable until reaching a target value Vt, and to supply the braking torque request signal to a braking means which converts it into a braking torque with effective braking torque value CFe. The braking control modules are configured to calculate a total difference of instantaneous braking torque &#x394;CFt as the sum of the differences between the CFr values and the CFe values of all modules. If the calculated &#x394;CFt is greater than zero when Vt is reached, the braking control modules increase the braking torque until a &#x394;CFt subsequent to reaching Vt has a zero or negative value, or until the maximum available adhesion signal has indicated that a controlled axle has reached the maximum available adhesion.
