Guide rail support suitable for withstanding forces transverse to a railway track, and assembly comprising such a guide rail support

A guide rail support intended to withstand forces exerted in a transverse direction of a railway track on a guide rail extending in a longitudinal direction of the track, the guide rail support comprising:

• a front face in the transverse direction intended to support the guide rail or an attachment part of the guide rail,
• a lower face in a third direction, wherein the third direction is substantially perpendicular to the longitudinal direction and to the transverse direction, and wherein the lower face transversely has at least a front section and a rear section, while the lower face is intended to define a contact plane with a track support, and
• at least one reinforcement rib transversely connecting the front face and the rear section of the lower face,
• wherein the rear section and the front section respectively define, in the contact plane, two distinct contact surfaces separated by a section of the contact plane that is devoid of any contact with the lower face, and
• wherein the reinforcement rib spans said section,
• wherein the rear section of the lower face comprises a first section, and a second section protruding transversely from the first section toward the front section, and
• wherein the second section has at least one additional attachment or abutment intended to interact with the track support, while the second section defines an additional contact surface in the contact plane.
