Summary

RailwayCare has long-termly provided grinding solutions for China Energy Investment Corporation, covering the Shenmu-Shuozhou Line and Huanghua Line, with a cumulative grinding distance of 20,000 kilometers.

Project Overview

RailwayCare provided comprehensive rail grinding solutions for the railway transportation network of Shenhua Group, a subsidiary of CHN Energy Investment Group. This two-year project covered multiple heavy-haul railway lines under Shenhua Group, aiming to improve track quality, extend equipment lifespan, and reduce maintenance costs.

As China's largest coal producer, Shenhua Group's railway network carries critical energy transportation tasks. Track quality directly impacts transportation efficiency and safety. RailwayCare's systematic grinding solution helped Shenhua Group address long-standing issues such as corrugation wear and side wear.
