摘要： Guide rail support (10) intended to withstand forces (F) exerted in a direction (T) transverse to a railway track on a guide rail (5) extending in a longitudinal direction (L) of the railway track. The guide rail comprises: a front face (31) in the transverse direction for supporting the guide rail (5) or an attachment part (23) of the guide rail, a lower face (33) in a third direction (V) substantially perpendicular to the longitudinal direction and the transverse direction, wherein the lower face transversely comprises at least one front section (43) and one rear section (45), and at least one reinforcement rib (35) transversely linking the front face and the rear section. The rear section and the front section respectably define, in a contact plane (P) of the lower face with the rail support, two distinct contact surfaces (47, 49) separated by a section (51) of the contact plane and devoid of any contact with the lower face, while the reinforcement rib spans the said section.
