The aim of the research is the study and

setup of a Vertical Loads Measurement Station (SMCV)

transmitted from the wheels to the rails during operation.

The research was developed through theoretical models,

numeric simulations, laboratory and online tests during

normal operation, in collaboration with the Italian Railway

Network (RFI) and the University of Rome La Sapienza

(Department of Civil, Building and Environmental Engineering

- DICEA).

The calibration of the measurement system, the uncertainties,

the repeatability and reproducibility of the findings

have been verified in the laboratory and on a test track.

Tests on a track in operation, with automatic data

analysis to identify the type of vehicle wheel arrangement,

axles, wheels and indicators of absolute and relative load

transmitted (imbalances), have allowed verifying the effectiveness

of the measurement station and its ability to detect

excess of threshold values that can be set for maximum

loads and related imbalances.
