Applications

High axle loads and very high cumulative tonnage. Wear resistance and a hard running surface matter more than speed.

Straightness, low residual stress and a consistent cross-section, so that long welded strings stay true at speed.

Tight curves with frequent acceleration and braking. Wear and corrugation control drive the choice of grade.

Abrasive conditions and heavy loads, often on in-plant track that is hard to reach for maintenance.

A wide, flat head for crane wheels, in grades hardened for the concentrated loads of a runway.

Mixed traffic on a standard alignment, where the profile is chosen to match the rest of the network.

Continuous welded rail on a corridor carrying both passenger and freight traffic.

Heavy axle loads over long distances, where wear life sets the maintenance interval.

In-plant and siding track, usually with tighter curves and lower speeds than a main line.

Crane runways and container yard track, where a crane concentrates very high loads on a short length of rail.
