GNEE rail has summarized the important factors influencing railway frog selection for rail switches include:
- Selection is based on the specific type and size of the rail turnout, sometimes requiring compatibility with other turnouts.
- The curvature radius affects the number and angle of railway frogs, with larger radii requiring more frogs for smoother transitions.
- Higher locomotive speeds demand frogs that ensure smooth train passage through the rail switch.
- The number of bifurcated railways influences the quantity of rail frogs required, typically one for a single turnout.
- Customized frogs may be necessary based on the actual terrain or slope of the railway laying.
- Customer-specific drawings may lead to the customization of railroad frogs to meet specific needs.
- Different locomotives (electric, mine cars, ordinary, high-speed) with varying loads and speeds require specific frog selections for track changes.
