What Are Grinding Trains?
A rail grinding train is a specialized maintenance vehicle that restores the profile and removes defects from railway tracks. By precisely grinding the rails, it ensures train operational safety, reduces noise and vibration, and significantly extends the lifespan of the rail infrastructure. This process is vital for maintaining efficient and reliable rail networks.
