Two Way Freight Car Derail: Left Throw Permanent Guide

Two Way Freight Car Derail: Left Throw Permanent Derail Guide

Principles and Applications

Derails are emergency car stopping devices designed to prevent unauthorized movement of locomotives and railcars. The principle behind derails is to lift the flange of the car wheel and drop it off the rail, thereby disrupting the wheel path. This is critical to prevent accidents and keep the tracks safe.

Permanent derailing is achieved with permanently installed hinged derails. These derails are for specific rail sizes and types, exposed rail track and wooden ties. They are especially important in active rail siding areas where the risk of movement is higher. By installing derails, railroads can comply with OSHA, FRA and DOT regulations and protect people and equipment from harm. Hinged derails with the ability to be padlocked in either position provide a reliable solution to prevent unauthorized movement and rail safety.

Two way derails are for freight cars and 4-axle locomotives, a robust solution to prevent movement. These derails have a unique design to make installation and removal easy, ideal for both temporary and permanent derailing applications. For exposed rail track and wooden ties, two way derails accommodate 100-142 lbs. per yard.

Included is a blue derail sign and holder, a visual warning to operators of the derail’s presence. This is critical to make sure all personnel know of the derail, for safety on the tracks. Two way derails are an essential part of rail safety, to prevent railcars from hitting each other or escaping onto the mainline, to protect equipment and personnel.

Types and Uses

There are different types of derails for different applications and uses. Permanent derails like hinged derails provide permanent derailing and are for exposed rail track and wooden ties. These derails are for situations where a long term solution is needed to prevent unauthorized movement.Portable derails like the SaberTooth portable two way freight car derail provide a temporary derailing solution. These are for freight cars and 4-axle locomotives, for flexibility and ease of installation. The choice of derail depends on rail size, tie spacing and type of locomotive or railcar being used. For example 6-axle locomotives require a specific type of derail that can accommodate their longer wheel base.

Understanding the different types and uses of derails is key to choosing the right product for the application. This will ensure effective prevention of movement and protection against hazards, to keep rail operations safe and intact.

Installation and Considerations

Installation of derails requires consideration of several factors, tie spacing, rail weight and type of locomotive or railcar being used. Permanent derails like hinged derails must be configured for the specific rail size and type and installed on exposed track and wooden ties. This will ensure the derail is properly aligned and secured to prevent movement.

Portable derails on the other hand are tool free installation and can be placed on the rail track. This makes them a convenient solution for temporary derailing needs. When installing derails make sure the product is properly secured to prevent removal or tampering. Also installation should be done according to the manufacturer’s instructions and safety regulations like OSHA and DOT.

Two Way Derail

Derails are emergency car stopping devices to prevent movement of a locomotive or railcar.

The derail lifts the flange of the car wheel and drops it clear of the rail, impeding forward movement.

OSHA, FRA and DOT regulations require derail protection for all active rail siding.

Derails prevent these railroad accidents:

• Railcars hitting each other.

• Unauthorized or premature removal of cars by locomotive.

• Rollaway car escaping out onto mainline.
