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.

The contents of this paper are arranged as follows. First, the mechanical qualities of ballast bed and the impact force on tamper at different test positions are compared experimentally in Section 2.Then, a tamping-ballasted track model is constructed by the coupling of DEM and multibody dynamics (MBD) in Section 3.Based on this, the …

By: Adam Burns. Railroad maintenance-of-way has long been an important part of railroading although not always mechanized like it is today. During the 19th century the work was performed entirely with manual labor. Large section gangs could be found all along the main line keeping it serviceable on a daily basis. Contents.
