What is a Fish Plate in Railway?

Railways are a vital mode of transportation across the world, and millions of people and tons of freight rely on railways for safe and efficient transportation. The railway track is the backbone of the railway system, and it is essential to maintain the track to ensure safe and smooth operation of the trains. The fish plate is an essential component of the railway track, and in this article, we will discuss what is a fish plate in railway, its functions, and how it is manufactured.

A fish plate, also known as a splice bar or joint bar, is a metal bar that is used to join two rails together to form a continuous track. It is a vital component of the railway track and plays a crucial role in ensuring the safety and efficiency of the railway system. Fish plates are generally used to join rails of the same size and profile, but they can also be used to connect rails of different sizes and profiles.

Functions of Fish Plate in Railway

The primary function of a fish plate is to join two rails together to form a continuous track. However, there are several other functions of a fish plate that are equally important:

  • To maintain rail alignment: The fish plate ensures that the rails are aligned correctly and maintain their proper position. Any misalignment can cause derailment, which can result in catastrophic accidents.
  • To distribute load: The fish plate helps to distribute the load evenly across the two rails. It prevents excessive stress on any one rail and helps to prolong the life of the rails.
  • To reduce wear and tear: The fish plate helps to reduce wear and tear on the rails by preventing them from shifting and grinding against each other.
  • To absorb shock and vibration: The fish plate helps to absorb the shock and vibration caused by the passing trains. It reduces the noise level and helps to maintain the comfort of the passengers.

Manufacturing of Fish Plate

Fish plates are typically made of high-quality steel or other metals that have high tensile strength and can withstand the stress and strain of the railway system. The manufacturing of fish plates is a complex process that requires specialized knowledge and equipment.

Material selection: The first step in the manufacturing process is to select the material for the fish plate. The material should have high tensile strength, excellent corrosion resistance, and good weldability. Common materials used for fish plates are high carbon steel, low carbon steel, and stainless steel.

Cutting and shaping: Once the material is selected, it is cut and shaped according to the required dimensions. The length, width, and thickness of the fish plate are critical factors that need to be carefully controlled during the manufacturing process.

Heating and forming: The next step is to heat the material and form it into the required shape. The heating process softens the metal, making it more malleable and easier to shape.

Forging and rolling: Once the material is heated, it is forged and rolled to the desired shape and size. The forging and rolling process helps to strengthen the metal and improve its resistance to wear and tear.

Heat treatment: After the forging and rolling process, the fish plate is heat-treated to improve its strength and durability. The heat treatment process involves heating the fish plate to a high temperature and then cooling it rapidly to improve its properties.

Surface treatment: The final step in the manufacturing process is to apply a surface treatment to the fish plate. The surface treatment helps to protect the fish plate from corrosion and other forms of damage. Common surface treatments include galvanizing, painting, and coating.

In conclusion, the fish plate is a vital component of the railway track, and it plays a crucial role in ensuring the safety and efficiency of the railway system. The fish plate joins two rails together, maintains their alignment, distributes the load evenly, reduces wear and tear, and absorbs shock and vibration. The manufacturing of fish plates is a complex process that requires specialized knowledge and equipment. The material selection, cutting and shaping, heating and forming, forging and rolling, heat treatment, and surface treatment are the main steps in the manufacturing process.

Specifications of Railway Fish Plate

The specifications of the railway fish plate are crucial to ensure the safety and durability of the railway system. Here are some of the key specifications of a high-quality railway fish plate:

Material: The material used for the fish plate should be of high quality and should have high tensile strength, excellent corrosion resistance, and good weldability. Common materials used for fish plates are high carbon steel, low carbon steel, and stainless steel.

Dimensions: The fish plate should be the correct length, width, and thickness to ensure a proper fit with the rail tracks. The dimensions of the fish plate should be carefully controlled during the manufacturing process.

Surface Finish: The fish plate should have a smooth surface finish to reduce wear and tear on the rails and prevent damage to the wheels of the train.

Selection Guide for Railway Fish Plate

Choosing the right type of fish plate is essential for the safe and efficient operation of the railway system. Here are some factors to consider when selecting a fish plate:

Rail Type: The type of rail used in the railway system should be considered when choosing a fish plate. Different types of rails require different types of fish plates.

Rail Size: The size of the rail should also be taken into consideration when selecting a fish plate. Different sizes of fish plates are available for different sizes of rail tracks.

Application: The application of the railway system should be considered when selecting a fish plate. Heavy-duty railways require stronger and more durable fish plates than standard gauge railways.

Quality: The quality of the fish plate is critical for the safety and longevity of the railway system. It is important to choose a high-quality fish plate that meets the required specifications and standards.

Other Useful Information

Here are some other useful information about railway fish plates:

Maintenance: The fish plate should be regularly inspected and maintained to ensure its proper functioning. Any signs of wear and tear should be addressed promptly to avoid any accidents or damage to the railway system.

Installation: The fish plate should be installed correctly and securely to ensure its proper functioning. It is important to follow the manufacturer’s instructions and guidelines during installation.
