In railway freight transportation, wheelsets and trolleys (also known as bogies) are the fundamental undercarriage assemblies that support wagons, guide them along the track, and ensure safe, efficient operation under heavy loads and harsh conditions.
A railway wheelset consists of:
Two solid (monobloc) steel wheels
A forged axle
Bearings and axle boxes for smooth rotation within the bogie frame
| Parameter | Typical Value |
|---|---|
| Axle Load | 22.5 – 30 tons |
| Wheel Diameter | 840 – 920 mm (freight) |
| Wheel Material | Forged steel (e.g., CL60, ER7) |
| Tensile Strength | 850 – 950 MPa |
| Standard Compliance | EN 13260/13262, AAR M-107/M-208 |
Wheelsets are designed to handle extreme vertical and lateral loads, resist rolling contact fatigue (RCF), and operate for millions of kilometers with minimal maintenance.
