AI Technical Summary

Technical Problem

Existing railway sleepers with recesses for accommodating balises require a relatively large height to prevent electromagnetic interference, which can lead to structural inefficiencies and increased risk of balise damage during maintenance.

Method used

A railway sleeper made of composite material without metal reinforcement, featuring a recess bordered by upright walls that extend in both longitudinal and transverse directions, allowing for a more compact design that minimizes electromagnetic interference and protects the balise.

Benefits of technology

The composite railway sleeper with a recess design maintains the integrity of the balise by reducing electromagnetic interference and providing enhanced protection against impacts, while also allowing for easier installation and maintenance.
