Railway Frog

A railroad frog, also known as a railway frog or simply a frog, is a crucial component in railroad or railway tracks. Its main function is to provide a smooth and efficient intersection or crossing point where two rails meet. The design of the frog allows train wheels to navigate the transition from one track to another or to a different direction on the same track.

Railroad track frogs is also categorized by structure into a fixed frog and a movable point frog (swingnose crossing). GNEE offers railrway frogs and various track materials. If you have any inquiries or need more details, please don't hesitate to get in touch with us.

Fixed Frog

● Combined frog

The combined frog is made by cutting and assembling steel rails and other parts. It includes components like the crossing nose, wing rail, spacer iron, and frog pad.

● One-piece cast frog

The one-piece cast frog is a type of railroad frog made with manganese steel casting. This advanced alloy gradually hardens with use, offering excellent wear resistance and impact durability for the crucial frog components.

Movable point frogs

Movable point frogs, also known as swingnose crossings, differ from fixed railroad frogs as they have special movable components like swingable wing rails or crossing noses. By adjusting the position of these movable parts in the frog, the working side of the wing rail or crossing nose can overlap, providing a continuous path for passing trains and allowing for increased speed.

These movable point frogs extend the frog's lifespan, typically 6-9 times that of the same model of high manganese steel cast frogs. Additionally, they reduce maintenance and repair work by 40%, significantly minimizing the impact on the track when trains pass through.

The railway frog plays a crucial role in guiding train wheels smoothly during track switches. It ensures safe transitions between tracks by facilitating seamless changes in direction. The frog's function is to minimize wear and tear on both train wheels and tracks, maintaining proper alignment and contributing to the overall efficiency and safety of the railway system.
