: A method for monitoring a set of railway points having a points machine (1), wherein the point machine (1) comprises a housing (2), a points actuator arranged in the housing (2) and an adjusting rod (3) extending from the housing (2) for coupling to a set of railway points, comprises: - providing a piezoelectric sensor (6) arranged on the housing (2), - detecting measurement signals from the piezoelectric sensor (6) during an actuating operation of the points machine (1), wherein periodic components of the measurement signal are at least partially filtered out in order to obtain signal components representative of a non-periodic change in the strain of the housing (2), and - evaluating a time course of the signal components representative of the non-periodic change in strain in order to identify deviations from a target state.
