The commonly accepted way to ballast model railway lines is to utilise fine granite chippings, ideally in a scale smaller than the one you're working in. The scale of ballast, its colour, quantity and appearance are considerations for better-looking track.
Maintenance to restore the design level is usually by tamping. In this process, the track is raised and vibrating tines inserted into the ballast to squeeze it horizontally in the direction of the track, raising the level of the ballast surface. This reduces the density and disturbs the structure of the ballast, which has become established ...

Apart from holding the railway lines in place and providing support for heavy trains to pass on, here are the other functions of the stones called track ballast: 1. The stones don't allow vegetation to grow on railway tracks which could weaken the ground on which the railway lines run. 2. Track ballast also keeps water from reaching the track ...

You can find this in each category of our website for O gauge, HO gauge, G scale and garden model railroads. 5 lb bag of ballast for large projects.Also great for doll house, architecture landscaping, craft projects, flower pots, etc.
In addition to the ballast shear resistance, there are various interfaces in rail track such as ballast-sleeper (timber or concrete), ballast-resilient pads (under sleeper pads-USP or under ballast mats-UBM), and ballast-subgrade (or subballast) significantly influencing the overall shear behavior.
Apart from holding the railway lines in place and providing support for heavy trains to pass on, here are the other functions of the stones called track ballast: 1. The stones don't allow vegetation to grow …
Specialist bedding stone made from natural stone used for laying below railway sleepers.
Stone ballast is a layer of small, crushed stone that is used in the construction and maintenance of railway tracks. It serves several purposes: It provides a solid foundation for the railway track. The ballast forms the track bed, upon which the railway sleepers (also called ties or crossties) are laid. The sleepers hold the rails in place and ...
Regulators are used to correct the track's ballast profile by redistributing ballast to the right areas of the ballast bed (beneath the track) to give the track lateral stability. The even bed of stone prevents the track from …

Railway ballasts are broken pieces of hard rock within the grain size range of 25mm - 60mm, over which the railway tracks are laid. Quarries in dolerite, greywake, shale, pebbles and granitic rock formations are some of the major sources of large stones that may be selected as railway ballast based on a range of properties.
High quality unweathered rock, generally used in railway lines, complies with Kiwirails specification. Winstone Aggregates track ballast conforms to the new Ballast Track Specification 140, tested by our IANZ laboratories every 1000m3. At agreed upon intervals the test reports are distributed to assist with certification requirements.
