Technical Parameters
Steel Rail Main Function
| Function | Technical Description | Key Features/Examples |
|---|---|---|
| Load Bearing | Supports vertical loads (static + dynamic) from trains and distributes to subgrade | - Heavy-haul rails (e.g., 75kg/m) handle 30+ ton axle loads |
| Guidance | Wheel flanges interact with rail inner surfaces to maintain direction | - High-speed tracks maintain ±1mm gauge tolerance at 350km/h |
| Smooth Ride | Minimizes vibrations and noise through continuous welded rails (CWR) | - CWR reduces noise by ~10dB vs. jointed rails |
| Track Switching | Turnouts enable route changes with movable components | - High-speed turnouts (e.g., 60kg/m-18#) allow 160km/h diverging speeds |
