Railway Buffer

Overview

This is a railway-dedicated buffering and safety solution designed to effectively control impact and loads generated in railway vehicles and infrastructure, while protecting structures and equipment in emergency situations. Large amounts of energy are generated in various situations such as vehicle coupling, stopping, and collision, and the key is to absorb and disperse this energy safely and reliably. Railway buffers are typically used to mitigate impacts between rail vehicles and play a critical role in absorbing collision energy.

Based on technologies optimized for railway environments, KOBA provides a wide range of products including coupler buffers, coupler deformation tubes, side buffers, anti-climbers, gas springs, and end stop buffers, enhancing the overall safety and reliability of railway systems.

Each product applies viscoelastic, hydraulic, and gas-based technologies to effectively absorb large impact energy and maintain stable performance even under repetitive load conditions.
