Transit & switch grindingHarsco RGH20C Rail Grinder
The Harsco RGH20C is a 20-stone transit and switch grinder designed for switches, guarded curves, road crossings and complex track structures. Its independently controlled hydraulic grinding units operate across the rail head and can be fitted with verified 152 mm wheel configurations.
What is the Harsco RGH20C?
RGH20C is commonly used for the 20-stone configuration within Harsco Rail’s RGHC transit and switch grinder family. Harsco describes the platform as suitable for switches, guarded curves and road crossings, with adjustable-gauge versions available. Independent grinding heads allow different rail-head positions to be treated under preset pattern control.
This page documents the RGH20C model and ordering information for its grinding consumables. For a broader comparison of Harsco platforms, see the Harsco rail grinding guide.

How the RGH20C grinding system works
Select pattern
The operator selects a preset grinding pattern for the required rail-head profile and track structure.
Position heads
A linkage rotates each unit while translating it across the rail from gauge to field side.
Control power
Each hydraulically driven grinding unit can be controlled independently during the pass.
Contain debris
Protective skirts, spark suppression, water systems and dust collection manage the grinding environment.
Typical RGH20C applications
Independent head control supports grinding around complex turnout components.
Rail-head treatment where guard rails and restricted geometry require flexible head positioning.
Specialty grinding through embedded or constrained track structures.
Profile correction and surface-defect treatment on metro, commuter and urban rail networks.
