Introduction to Fish Plates in Railway Systems

Fish plates are often overlooked champions in railway frameworks, fastening rail ends while permitting heat-induced stretching and weight sharing. Whether you’re overseeing a robust freight route or a city transit network, grasping the types of fish plates is essential for enhancing efficiency and durability. Let’s explore their purpose, categories, and how they boost your rail initiative.

What Are Fish Plates and Why Do They Matter?

Fish plates, sometimes called rail joint bars, are metallic or synthetic panels that join two rail ends, creating a smooth pathway. Their value stems from their capacity to sustain alignment and firmness across varied settings.

The Role of Fish Plates in Rail Infrastructure

Fish plates fulfill two main purposes:

  • Link Rail Ends While Permitting Heat Expansion: Rails lengthen and shrink as temperatures shift. Fish plates offer a sturdy connection that adjusts to this motion without weakening stability.
  • Spread Weight Uniformly: By distributing the burden of moving trains, fish plates stop track distortion, cutting down wear and upkeep expenses.

Without them, rail ends might drift apart. This could lead to derailments and pricey fixes.

Key Components of a Fish Plate System

A standard fish plate setup consists of:

  • Bolts and Nuts: They anchor the panel to the rail ends securely.
  • Insulation Elements: These are employed in electrified routes to block current seepage.
  • Materials: Choices vary from steel to synthetic blends or rust-proof alloys, based on the purpose.

These elements collaborate to deliver a strong bond suited to particular railway demands.

Choosing the best track tools and materials

Good quality track materials can help increase track-up time and decrease maintenance requirements. Here are some of the best materials to choose from:

Tee Rails:

You can buy these by the piece, foot or per net ton. At NARP, you can purchase these new or used rails (called relay rails) and scrap tee rails to meet your every need.

Crane Rails:

These rails are preferred over tee rails for light rail (LRT) or tramway operations to help your line run smoothly. At NARP, crane rails come in a variety of sizes.

Switch Stands (or switch controls):

These require a human operator to switch tracks between positions manually. You can purchase these new in many different styles or ask about relay or reconditioned switch stands for a discounted price. 

Switch or Connecting Rods:

Both are available in varying lengths and brand new or relay. 

Turn-Outs and Switch Components:

You may also know these as switch point protectors, switch points, switch rails, or point rails. They are used to help your rail equipment move between tracks. Choose between new, relay, and reconditioned. 

Tie Plugs:

When replacing your ties, these specially designed pieces of wood are used to plug the holes. Modern rail demands now require these tie plugs to replace spikes when filling and fastening cross ties. NARP only sells new tie plugs.

Pandrol Clips (or rail fasteners):

When used with Pandrol plates, these help minimize track installation time and provide a much lower maintenance cost (compared to outdated rail fastening systems. 

Derail:

When you need to prevent movement of the car or train beyond a fixed point, you’ll require a derail. When delivered to you, they are defaulted to the “On” position for safety. Portable derails are reusable. They can be moved to new sections of the railway anytime. 

Hook Twin Tie Plates:

These are installed behind the switch heels, guard rails, and for frogs. Their versatile design makes them ideal for most rail sections. Look for ones with pre-drilled holes to hook into the tie plates. 

Adjustable Rail Braces:

This unique product adjusts for various uses. They’re quick and easy to modify, saving you time and money on maintenance and service. 

Rail Anchors:

To prevent the longitudinal movement of rails, install rail anchors. The four most commonly used rail anchors include Improved Fair, XL-1, EXI, and Unit Anchors.
