Compact production grindingLoram RGC Rail Grinder
The Loram RGC is a compact production rail grinder for passenger, commuter, freight and high-speed networks. Loram publishes configurations with up to 40 grinding stones, 22.4 kW motors, grinding speeds up to 32 km/h and track gauges from 1,067 to 1,435 mm.
What is the Loram RGC?
The RGC combines mainline production-grinding capability with a reduced platform footprint for passenger, commuter and urban networks. Loram states that it is designed around international construction, fire-safety, axle-load and clearance requirements, including the W6A clearance diagram.
Independent tilt-and-shift modules position the stones across the rail head. Depending on the delivered configuration, the RGC can support production grinding on plain line and selected specialty assets, including work around third-rail infrastructure.

Dust collection, fire suppression, water sprays and flame-resistant hydraulic fluid.
Loram RGC rail measurement and surface imaging
Loram lists RailPro®, optical transverse and longitudinal rail measurement, and HD geo-tagged rail surface imaging as optional features. These systems can support grind planning and post-work verification.
Measurement equipment is optional. Confirm the installed sensors, software, data outputs and acceptance procedure for the individual consist.
Where is the Loram RGC used?
Production grinding where clearances and axle loads favour a compact consist.
Rail-head reprofiling and treatment of corrugation and profile deviation.
Loram describes the RGC as EN 13231 capable for applicable grinding-quality requirements.
Configurable for energised or de-energised third-rail applications.
Loram RGC standards: EN 50128 and EN 13231
Loram states that machine software is developed to EN 50128 and that the platform is EN 13231 capable. Project acceptance, local rules and delivered configuration remain controlling.
Loram RGC vs C44 vs RG400
Selection summary: RGC is the compact option in this comparison; C44 expands the international production configuration, while RG400 targets higher-output production programs. Final selection depends on clearance, axle load, possession time, required metal removal and the delivered consist.
How to specify grinding wheels for a Loram RGC
