Railroad Ballast, Types And Purpose

One often forgotten aspect of the ballasting system is what is known as sub-ballast or sub-grade. This layer of crushed stone or even pavement, as some railroads today now use acts as a moister barrier and added support system for the railroad track structure above (including the rails, ties, and ballast).

Track ballast Wikipedia

Track 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 vegetation that might interfere with the track structure. Ballast also holds the track in place as the trains roll over it.

How to Realistically Ballast Your Railroad

Sep 28, 2018For many modelers, adding ballast is one of the first steps in the process of creating realistic scenery for your layout. When planning this stage, traditional gray stone gravel will likely come to mind, but take a closer look at real world railroading, and you’ll notice that each railroad and each type of railroad has its own very distinctive look to it.
