Railway ballast and its maintenance
Railway ballast and its maintenance. A clean and homogeneous ballast bed is an essential pre-requisite for the wheel-on-rail system to function smoothly. To fulfil its load distribution function, the gradation of railway ballast has to be kept in relatively tight limits. Too uniform gradation or too many fines in the ballast both reduce the ...

Ballast | The PWay Engineer
Functions. This brings us onto the functions of the ballast, once it is put down on the railway. It distributes the load of the passing trains from the rails and sleepers above it into the formation sand ground below it. It further spreads the load. It allows water to drain through it, into either the underlying ground or the track drainage.
