Pakistan Railways has acquired a state- of- the- art ballast cleaning machine for automatic track maintenance. Normally, the ballast ( little rocks) is damaged owing to ground movement, vibrations, contraction and heat expansion. The new machine will help clear the old ballast and way for new ballast to keep the wooden cross ties on the tracks stable. The machine will clear cover 300 meters of tracks with new ballast within an hour, saving significant time and resources and keep the railway tracks smooth and running. The machine has been initially introduced in the Punjab on a test basis.
