A rail vehicle having rail wheels accommodated to guide the rail vehicle along a railway track. Each of the wheels is connected to the vehicle by an intermediate axle box that includes at least one accelerometer. A measurement system includes a receiver for receiving signals from the at least one accelerometer, and a vehicle-railway track interaction model that estimates the expected signals from the at least one accelerometer. The receiver and the vehicle-railway track interaction model connect to a comparator to compare the measured signals and the expected signals from the at least one accelerometer. The comparator connects to a tuning portion of the measurement system, which tuning portion is arranged to adjust parameters of the vehicle-railway track interaction model so as to provide a closer fit of the estimation of the expected signals from the at least one accelerometer with the measured signals from the at least one accelerometer.
