AI Technical Summary

Technical Problem

Existing methods for laying pre-assembled track sections longer than 18 meters face issues such as damage from friction and torsional forces due to variations in wagon spacing during train acceleration or braking, leading to potential deterioration and derailment risks.

Method used

Equipping wagon floors with center pivot and lateral sliding plates, along with fixed load points, to absorb friction and torsional stresses, allowing safe transport of longer track sections without damage.

Benefits of technology

Prevents damage to track elements and ensures safe assembly by absorbing friction and torsional forces, enabling the use of longer track sections without cutting or welding, thus enhancing safety and efficiency.
