GMC-12 is a rail grinding train is a specialized maintenance-of-way vehicle that uses Maximum 10 high-speed rotating abrasive stones to restore worn steel tracks and remove surface

8-10 engine-driven grinding wheels are mounted underneath the train cars and pressed against the rails at controlled angles.

Removes fatigue cracks, corrugation (washboard-like ripples), and surface deformation caused by heavy freight or passenger loads

The FGM series rail milling and grinding train is positioned as a major railway transit equipment that is lightweight, intelligent, safe and reliable, efficient and clean, and has low maintenance costs.

It mainly targets rail defects such as corrugation, head checking, shatter crack, etc. Through efficient milling and grinding, it can achieve precise profile repair and perfect smoothness improvement of rails. The milling operation process is clean, without fire hazards, and the iron chips collection rate reaches \bm{99\%}.

It has the function of turnout milling and grinding, which can conduct automatic operation of tracks with obstacles such as expansion rail joints, level crossings, and civil air-tightened door areas.

The milling machine is equipped with a rail measuring device that can measure corrugation and profile to meet EN 13231-3.
