There are various types of single turnouts and compound turnouts for track line connection. There are vertical crossovers and diamond crossovers. The combination of turnouts and crossovers includes crossovers, crossovers and ladder lines, etc. These devices are called special tracks in railway engineering.
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.
Railway frog function
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.
