Tamping machines are used for raising, straightening and tamping track. There are two kinds of tamping machines. The universal tamping machines are also used for raising, straightening and tamping points. The continues tamping machines have movable tamping units that can be operated independently of each other. Tamping tines (i.e. vibrating arms) vibrate into the ballast, before moving together to squeeze the ballast under the sleepers. The measuring equipment on the tamping machine ensures that the level is accurate to a few tenths of a millimetre.
