27-12-2021 · According to Brian Solomon's book Railway Maintenance, The Men and Machines That Keep the Railroads Running, today the typical layout for a well-ballasted railroad track system is stone lined to the top of the railroad ties protruding roughly 14 inches to either side. From this point the rock is tapered away on a "3-to-1" slope to an eventual distance of 9 feet,

These types of ballast are used only in special circumstances. Functions Of Ballast. The ballast serves the following functions in a railway track.
Read MoreTrack ballast forms the trackbed upon which railroad ties (sleepers) are laid. It is packed between, below, and around the ties. It is used to bear the load from the railroad ties, to facilitate drainage of water, and also to keep down vegetationthat might interfere with the track structure. Ballast also holds the track in place as the trains roll over it. A variety of materials have been used as track ballast, in
