A modular fastening for track crossings, comprising:

• a lower plate on which there is placed
• an upper plate, and
• an outer shoulder, located at each end of the plates, comprising means for anchoring the fastening on a support surface, wherein:
• the plates and the outer shoulders are attached to one another by an adhesive, thereby forming a single-block assembly,
• the upper plate comprises a smooth central segment located between two grooved areas located in correspondence with the ends of the upper plate,
• the fastening comprising two inner shoulders comprising lower grooves which can engage and fit into a plurality of positions on the grooved areas of the upper plate, where said inner shoulders comprise means for housing and securing an elastic fastening clip for fastening a railway rail;
• and
• wherein the upper plate further comprises a longitudinal channel running from one grooved area to the opposite grooved area and passing through the smooth central segment, where the inner shoulders in correspondence with the lower grooves comprise a guide bridge-like channel.
