Railway Ballast Function Of Stones In Railway Track

Railway ballast or track ballast refers to crushed stones placed under the railway track. It forms the trackbed for sleepers to lay on. Although some tracks are ballastless, the ballasted track remains a dominant infrastructure of the most railroad tracks.

Functions of Track Ballast alongside the Railway Track

2020-6-30  What is track ballast To start with, the stones that you see lying close to the railway tracks are collectively called track ballast. It basically forms the trackbed on which the rail sleepers are kept. Track ballast is packed between the sleepers, in the areas below, and on the sides of railway tracks.
