Model overview

What is the Loram RGX?

RGX is Loram’s compact production and specialty grinding platform for railways where a full-size mainline grinder may not suit the infrastructure. Loram lists ten possible consist configurations with 20–40 grinding stones. Each grinding car has its own engine, traction, water tank and hydraulic systems, providing operational redundancy across multi-car arrangements.

This entry covers the RGX platform and its published operating envelope. For comparisons with other Loram machines, see the Loram rail grinding guide.

Operating principle

How the RGX grinding system works

01

Measure

Optional transverse and longitudinal profile systems and rail-surface imaging document rail condition.

02

Plan

Rail Pro® grind-management software supports the planned motor angles and grinding programme.

03

Grind

Independent tilt-and-shift modules position rotary abrasive stones across the rail head.

04

Control

Dust collection, noise suppression and machine systems support work in constrained rail environments.

Use cases

Typical RGX applications

Commuter and transit networks

Production grinding where compact geometry and controlled axle loads are required.

Tight curves and steep grades

Routes with curves down to the published 35 m reference and grades up to 8%.

Specialty grinding

Flexible consists for varied rail conditions and shorter or constrained work sites.

Selected mainline work

Medium-scale production work where the railway’s gauge, clearance and capacity requirements suit RGX.

Configuration guide

RGX consists and machine identification

Loram describes ten consist configurations ranging from 20 to 40 stones, with an optional support car. The machine can use different stone sizes and grits. Confirm the exact car arrangement, installed grinding head, equipment plate and operator documentation before specifying consumables.
