Zusammenfassung:	A method for estimating a longitudinal acceleration of at least one railway vehicle by means of an accelerometric sensor means is described, comprising the steps of:executing a calibration phase including the steps of:solving the following system, in order to determine the values of the first direction cosine k1, the second direction cosine k2 and the third direction cosine k3:{k1ax(tc⁢1)+k2ay(tc⁢1)+k3az(tc⁢1)=aref(tc⁢1)k1ax⁢(tc⁢2)+k2ay⁢(tc⁢2)+k3az⁢(tc⁢2)=aref⁢(tc⁢2)k1ax⁢(tc⁢3)+k2ay⁢(tc⁢3)+k3*az⁢(tc⁢3)=aref⁢(tc⁢3)following the calibration phase, determining an estimated longitudinal acceleration value a1on(ti1) by means of the sum of a multiplication of the first direction cosine k1 with a first acceleration ax(ti1), a multiplication of the second direction cosine k2 with the second acceleration ay(ti1) and a multiplication of the third direction cosine k3 with the third acceleration az(ti1).
