    Kinematic diagram of a ballast cleaner equipped with ACS ...
    A railway ballast cleaning machine, or ballast cleaner, is heavy equipment that digs up, screens, and returns clean gravel (ballast) to the track bed, removing dirt, fines, and contaminants to improve drainage, stability, and lifespan of the track for better performance and safety, with models like Plasser & Theurer's RM series or Loram's HP cleaners processing tons of material hourly.

    How it works 
    • Excavation: Excavating wheels or chains dig up ballast from the shoulders and under the ties (sleepers).
    • Screening: The material passes through vibrating screens that separate fine particles, dirt (fouling material), and contaminants.
    • Disposal: Waste material is discharged away from the track, often into dump cars.
    • Return: Clean, good-quality ballast is returned to the track, often with scarifiers breaking up mud caps under the ties to improve drainage.

    Key functions & benefits 
    • Improves drainage: Removes fines that block water flow, preventing waterlogging and heaving.
    • Enhances stability: Restores the track's stiffness, strength, and geometry, reducing maintenance needs.
    • Extends track life: Maintains permeability, ventilation, and prevents premature failure of sleepers and rails.
    • Increases efficiency: Can process large volumes of material quickly (e.g., thousands of tons per hour) and often allows for work without speed restrictions.
    • Reduces costs: Lowers long-term maintenance, tamping, and herbicide costs. 
    Types of machines 
    • Shoulder Ballast Cleaners (SBC): Focus on cleaning ballast from the shoulders, like Loram's HP SBC.
    • Ballast Bed Cleaners: Clean the entire ballast bed, often including the area under the ties (e.g., Plasser & Theurer's RM series).
    • Undercutters: A specific type that removes ballast from beneath the ties.
