Railwaycare provides polishing services at the jinan Railway Bureau in China

China Railway Jinan Group Co., Ltd. employs large-track maintenance machinery to carry out mechanized rail grinding across its network of approximately 5,115 kilometers of operating lines. The Group is equipped with advanced rail grinding vehicles such as the GMC-96B, capable of controlling single-pass grinding depth within 0.1 millimeters with an error margin of no more than 0.05 millimeters, and can operate in multiple modes to address various rail defects. During intensive maintenance periods, the Group coordinates and deploys all 156 large-track maintenance machines across its network for concentrated operations. To date, the total mileage of precision rail grinding completed by China Railway Jinan Group has exceeded 100,000 kilometers, marking the full transition of its major track maintenance and repair operations into the mechanized era.

To overcome these hurdles, we deployed the MRC-L260090, a premium replacement wheel engineered specifically for the Harsco system. This is not a generic substitute but a scientifically upgraded solution.

During field trials on a heavy-haul corridor, the MRC-L260090 wheels were tested against standard market offerings. The results were conclusive:

By switching to RailwayCare’s MRC-L260090,The advantage lies in the long-term tracking and experimentation over time. Through accumulated experience, we know which types of steel rails require which formulations. We use data analysis based on this experience to adjust the formulations accordingly.This case proves that selecting the right abrasive material is key to modern, efficient railway maintenance.
