Rail Safe / Energy Absorber

Shock Energy Absorber System

Rail Safe, a shock energy absorber system,rail_safe2 improves rail transportation safety by providing high-energy absorption through a novel patented design. The system provides excellent damping and force magnitude control through solid-to-viscous reversible phase transition of its core material.

Simulations of tank car collisions show that Rail Safe added between rail cars can significantly improve crashworthiness and mitigate collision damage.
