Abstract: Systems and methods for monitoring the integrity of a convoy of vehicles are described. The convoy can include a first vehicle and at least one second vehicle connected to the first vehicle. In one example, the system can include a communication line and a power supply line each arranged to be installed in the first vehicle and in the at least one second vehicle. The system can further include a control circuit arranged to verify whether the communication line is interrupted and verify whether the power supply line is interrupted. From the verifications, the control circuit may determine that both the communication line and the power supply line are interrupted and further determine that the second vehicle has disconnected from the first vehicle.

Abstract: 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.
