A measuring device (1) for loads acting on a rail (21), the device (1) comprising a support (3) defining a hole (4) having a first axis (A) adapted to being perpendicular and coplanar to an axis of symmetry (S) of said rail (21), at least one first and one second flat walls (12, 13) rigidly connected to the support (3) inside the hole (4), and at least one first and one second measuring instruments (16, 17) respectively supported on said at least one first and one second walls (12, 13), in which the first wall (12) is perpendicular to and crossing the first axis (A) and the second wall (13) is parallel to the first axis (A) and further that the first and second measuring instruments (16, 17) are adapted to measure respectively a first and a second shear loads (Y, Q) acting respectively on directions parallel to the first axis (A) and to the axis of symmetry (S).
