Rail Derailment Device

I. Product Overview

The Rail Derailment Device is a critical safety protection equipment independently researched and developed by Yuerui International, mainly deployed in railway marshalling yards, train maintenance depots, station track terminals and other key areas. Its core function is to guide the railway rolling stock (locomotives, freight cars, passenger cars) that are overspeeding, out of control or deviate from the normal track to derail in a pre-set safe area, thereby avoiding catastrophic collisions with track end facilities, buildings or other parked trains. Integrating optimized slope guiding structure, high-efficiency energy absorption technology and easy-to-install modular design, this product is fully compatible with high-speed railways, conventional railways and urban rail transit systems. It can effectively limit the damage scope of rail accidents, protect the safety of on-site personnel and equipment, and serve as an indispensable safety barrier for the global railway operation system.

III. Core Advantages

(1) Guided Derailment & Controllable Accident Scope

Adopting a scientific arc-shaped slope guiding structure, the device can accurately guide the derailed wheels to slide along the preset safe trajectory, avoiding random deviation and secondary splashing of the rolling stock. The multi-stage energy absorption module composed of high-density polyurethane can step-by-step absorb the huge impact energy generated during derailment, reducing the impact force between the rolling stock and the device by 60% compared with traditional products. This design not only minimizes the damage to the rolling stock body but also prevents the device itself from being damaged by impact, ensuring the controllability of the accident scene.

(2) Super High Strength & Long-Term Durability

The main body frame is made of Q500 high-strength low-alloy steel, which is formed by integral casting and precision machining, and undergoes strict normalizing and tempering heat treatment. Its tensile strength reaches ≥500MPa, and it can withstand the strong impact of heavy rolling stock without deformation or fracture. The surface of the frame is treated with hot-dip galvanizing + electrostatic spraying double anti-corrosion technology, which can effectively resist the erosion of rain, snow, dust and salt spray in coastal or cold regions. The service life of the product in outdoor harsh environments can reach more than 20 years, far exceeding the industry average level.

(3) Modular Design & Convenient Installation

The product adopts a modular split structure, which can be quickly assembled and installed without modifying the original track structure. The base is fixed with high-strength expansion bolts, and the installation process can be completed by 2-3 operators in 2 hours. The manual mechanical switching mode is simple and reliable, and the operator can switch the device between working and non-working states with a special wrench, which is suitable for the frequent switching needs of marshalling yards. The optional electric remote control mode can realize centralized control of multiple devices, improving the operation efficiency of large-scale railway yards.

(4) All-Environment Adaptability & Comprehensive Safety Protection

The product is specially designed for extreme environments, with a wide operating temperature range of -50℃~90℃, which can work normally in frigid areas such as northern Siberia and high-temperature areas such as deserts. The anti-slip rubber pad at the bottom of the device enhances the friction between the device and the track bed, avoiding displacement during impact. The product is equipped with a real-time state monitoring sensor (optional), which can feed back the working state of the device to the control center in real time. At the same time, the rounded edge design of all components avoids scratches on the rail and rolling stock wheels, protecting the integrity of railway components.

IV. Application Scenarios

This safety protection equipment is widely used in various railway operation scenarios around the world, including:

• Railway Marshalling Yards: Installed at the end of shunting tracks and classification tracks to prevent shunting locomotives or freight cars from overspeeding and colliding with track end stops;
• Train Maintenance Depots: Deployed in maintenance track sections to avoid accidental collision of maintenance vehicles or parked trains with maintenance workshops, cranes and other equipment;
• High-Speed Railway Stations: Installed at the exit of the station approach track to prevent high-speed trains from overspeeding and derailing during emergency braking or temporary parking;
• Urban Rail Transit Depots: Applied to the parking tracks of subway and light rail vehicles to ensure the safety of vehicles during non-operational storage, maintenance and overhaul;
• Industrial and Mining Railways: Used in the track terminals of mining areas and industrial parks to adapt to the harsh working environment of heavy-load freight cars and ensure the safety of loading and unloading operations.
