Rail Derailment Device

I. Product Overview

The Rail Derailment Device is a professional safety protection equipment independently developed by Yuerui International, mainly used in railway marshalling yards, maintenance depots, station tracks and other scenarios. Its core function is to actively guide the railway rolling stock that exceeds the safe speed or deviates from the normal operation track to derail in a controlled manner, avoiding severe collisions with track facilities, buildings or other trains. Integrating scientific structural mechanics design, high-strength material application and easy operation performance, the product is tailored to the operational characteristics of high-speed railways, conventional railways and urban rail transit. It can effectively reduce the damage range of rail accidents and protect the safety of personnel, rolling stock and infrastructure, making it an important safety barrier in the global railway operation system.

III. Core Advantages

(1) Scientific Derailment Guidance & Controlled Damage

Adopting the optimized inclined guide rail structure, the device can accurately guide the derailed wheels to move along the preset direction, avoiding random deviation of the rolling stock. The built-in polyurethane buffer component can effectively absorb the impact energy during derailment, reduce the impact force between the rolling stock and the device, minimize the damage to the rolling stock body and the track, and avoid secondary accidents caused by splashing of broken parts.

(2) Super High Strength & Impact Resistance

The main body is made of high-strength Q460 alloy steel, which is formed by integral casting and precision machining, and undergoes strict heat treatment process. Its tensile strength reaches ≥550MPa, and it can withstand the strong impact of heavy rolling stock without deformation or fracture. The surface is treated with galvanizing + anti-corrosion coating, which forms a double anti-corrosion barrier, effectively resisting rust, oxidation and corrosion from rain, snow, dust and chemical media in the outdoor environment, and ensuring long-term stable use.

(3) Flexible Adaptability & Wide Application

The modular design allows the device to be quickly installed and adjusted according to different rail models and track widths, perfectly adapting to the use needs of conventional railways, high-speed railway marshalling yards and urban subway maintenance depots. It can be applied to both freight trains and passenger trains, and is suitable for various complex scenarios such as straight tracks, curved tracks (curvature radius ≥300m) and ramp sections (slope ≤3%), with strong environmental adaptability.

(4) Simple Operation & High Safety Reliability

The manual mechanical control mode has a simple operation process, and the operator can complete the switching between the working state and the non-working state with a small force, which is convenient and efficient. The optional electric auxiliary control can realize remote operation, which is suitable for large-scale marshalling yards and other scenarios that require centralized control. The product is equipped with a state monitoring device, which can real-time feed back the working status of the device, and is equipped with an emergency reset function to ensure the safety and reliability of the operation process.

IV. Application Scenarios

This safety equipment is widely used in global railway operation and maintenance scenarios, including:

• Railway Marshalling Yards: Installed at the end of the shunting track to prevent shunting locomotives or freight cars from exceeding the limit and colliding with other facilities;
• Railway Maintenance Depots: Used in the maintenance track section to avoid accidental collision of maintenance vehicles or parked trains with maintenance equipment and buildings;
• High-Speed Railway Stations: Installed at the exit of the station track to prevent high-speed trains from overspeeding and derailing during temporary parking or emergency braking;
• Urban Rail Transit Depots: Applied to the parking track of subway or light rail vehicles to ensure the safety of vehicles during non-operational storage and maintenance.
