What is a railway sleeper plate?
Railway sleeper plates, also known as railway tie plates or base plates are made of mild steel, cast iron, wrought iron or malleable steel and are sandwiched between flat-bottomed rail feet and wooden sleepers to distribute the load over a larger area.
Types of Railway Sleeper Plates
Casting railway tie plates
Tie plates can be cast iron or cast steel, depending on the type of load and rail. Cast iron can be welded or fabricated, depending on customer requirements.
Single shoulder railway tie plates
For single-shoulder tie plates, the shoulder is designed at the field end of the plate. The short end or rail gauge end of the plate is placed inside the rail, which is why customers always ask for the width of the rail base. Single shoulder tie plates are typically used for rail weights from 56 lbs to 100 lbs.
Double shoulder railway tie plates
We currently use the double shoulder type. The older single shoulder type is available for various rail widths, with the shoulder located on the outside (field side) of the rail.
Railroad hook double tie plates
HTTP stands for hook twin tie plate and is widely used for turnouts that sit behind the bottom of the switch. To preserve wire spacing, HTTP often uses a single wire in pairs.
Functions of Railroad tie plate
Protect the sleeper from wear and tear
when the train running, because rail and wheel is not round, orbit dynamic impact such as the change of the intensity, can be as high as twice the train load, the impact of the so big strength is still likely to be damaging to the concrete sleeper. As a result, concrete sleeper often use composite railroad tie plate. This kind of tie plate is softer and can reduce dynamic impact to some extent.
Provide a flat contact surface for the rail bed
The upper surface of the rail sleeper cannot be absolutely flat. Originally in the projection area on the rail bed is not large, if the contact surface is uneven, so the contact area will be smaller. Therefore, the use of rail plate can provide flat contact surface, thereby increasing the contact area, reducing pressure.
Prevent rail crawling
At the place that rail tie plate touch with rail bed there are two "bulges", so this tie plate is called "Double Shoulder Tie Plate". Don’t look down upon these two bulges; they can prevent the rail track lateral movement. Friction coefficient of the composite double shoulder tie plate and the rail track is greater than the coefficient of friction between the rails and concrete sleepers, with Elastic fasteners used can provide sufficient lateral and vertical restraints.
For wooden sleepers, railroad tie plate has another function that is provide cant for the rail track
rail sleepers and rail tracks are not arranged vertically, but gauge side is inclined at an angle, so it can provide a better wheel-rail contact surface. The rail track inclination angle of North American is 1:40. For concrete sleepers, rail inclination angle is integrated in the rail sleeper, so that sleeper rail contact surface (Rail Seat) itself is inclined.
Features of railway sleeper plate
Strength and stability
The railway sleeper plate needs to be able to withstand the huge pressure and impact generated when the train is running, and it also needs to have sufficient stiffness and stability to ensure the smoothness and safety of the train operation.
Durability
The railway sleeper plate needs to have a long service life, be able to withstand long-term use and environmental erosion, and maintain good performance.
Waterproof
Since the railway sleeper plate is exposed to the environment for a long time, it needs to have good waterproof performance to prevent moisture penetration from affecting the railway line.
Fire resistance
The railway sleeper plate also needs to have good fire resistance to prevent fire damage to railway lines.
Lightweight
In order to improve the operating efficiency and energy saving of trains, the railway sleeper plate needs to be as lightweight as possible while ensuring its strength and stability.
Environmental protection
Modern railway construction emphasizes environmental protection and sustainability. Therefore, the production and use of railway sleeper plates need to minimize the impact on the environment, such as using environmentally friendly materials and low-energy consumption manufacturing processes.
Process of rail sleeper plate
The manufacturing process of track sleeper plates is a complex process involving several steps from raw material procurement to quality control. By ensuring that every railway plate meets the required strength and durability standards, the rail industry can provide safe and reliable public transportation to millions of commuters around the world.
Purchase of raw materials
The manufacturing process of railway sleeper plates begins with the procurement of raw materials, the quality of which is crucial as any impurities or defects will affect the strength and durability of the product.
Preparation
After the raw materials are purchased, they need to be sorted, cleaned and prepared for melting. The scrap is cut into small pieces and loaded into furnaces for smelting. The furnace is heated to high temperatures and the waste melts to form a uniform liquid.
Casting
Once the molten metal is ready, it is poured into molds specifically designed for casting steel sleeper panels. Sleeper plate molds are usually made of cast iron and each mold produces one plate. Liquid metal is carefully poured into the mold, and as it cools, it solidifies and forms the mold's shape.
List systematically
Once the railway sleeper plates are cast, they are removed from the mold and transported to the finishing area. Here, the railway sleeper plates are treated, cleaned, and painted to give them a smooth, shiny appearance. The finishing process also includes grinding the edges of the railway sleeper plates to ensure they fit together perfectly on the track.
Quality control
Quality control is a critical component of the manufacturing process. railway sleeper plates undergo rigorous testing to ensure they meet the required strength, durability and safety standards. The railway sleeper plate undergo non-destructive testing such as ultrasonic and radiographic testing. Each board is visually inspected for any flaws or imperfections.

FAQ
Q: What is Foreign Trade-Express?
Q: How to ensure the stability of the railway sleeper plate?
Q: What factors determine the size and shape of railway sleeper plates?
Q: What are the surface treatments for railway sleeper plates?
Shot peening: Use high-speed projectiles to spray the surface of the iron plate to strengthen its surface layer and improve its fatigue resistance and corrosion resistance.
Sandblasting: Use a sandblasting machine to blow sand on the surface of the iron plate to clean its surface and form a certain roughness to improve its adhesion.
Coating treatment: Apply a layer of paint to the surface of the iron plate to improve its corrosion resistance and aesthetics.
Q: How is the seismic performance of the railway sleeper plate achieved?
Q: How long is the service life of a railway sleeper plate?
During the design and manufacturing process, the selection of materials and the control of the manufacturing process are taken into consideration to ensure a long service life of the railway floor. At the same time, regular maintenance and upkeep is also required during use to maintain its good working condition and safety.
However, since the railway sleeper plate is exposed to the natural environment for a long time and will be affected by various environmental factors, such as temperature changes, humidity, chemical corrosion, etc., its service life may be affected to a certain extent. In order to extend the service life of the railway floor, corresponding measures need to be taken, such as regular inspection, maintenance and repair, and timely repair of damaged parts.
