The invention concerns a method for safe supervising train integrity, the method comprising: a) acquiring first position data (PI) of the first carriage (C1) via a first tracking unit (TU1) which is installed on-board of a first carriage (C1) and acquiring second position data (P2) of a second carriage (C2) via a second tracking unit (TU2) which is installed on-board of the second carriage (C2), wherein the position data (P1, P3) is related to a rail route coordinate system. b) determining a deviation Δ between a reference value which depends on the length L of the train and a position value which depends on position data (P1, P2) of at least one of the tracking units (TU1, TU2); c) detecting whether train integrity is given by analyzing the deviation; d) Repeating steps a) through c); wherein the tracking units (TU1, TU2) are part of on-board units (OBU1, OBU2) of an automatic train protection system. Thus a cost-efficient method for supervising train integrity which complies with safety level SIL4 can be realized.
