This is an undercutter. Ballast cleaners have a digging wheel that cleans along the side of the ties. Undercutters remove mud pockets and ballast fines from the sub-roadbed, and can also be used to lower track profile for increasing clearances.
@tiff5355 Ballast makes an easy drain for rainwater. When there's too much dirt between the stones, the drainage can become a problem. Besides that, clean ballast reduces noise.
