ferred to as ballast) used for railway track support is of major importance in establishing and maintain ing the characteris':ics of the track response and, consequently, the riding quality. For ballasted track, an elastic, noncemented, stable and weather resistant ballast bed, well laid and compacted on a
Track ballast (usually crushed stone), as it is known, is another important part of railroad infrastructure. Although it may just look like plain ole gravel this stone plays a vital role in acting as a support base for the railroad ties and rails as well as allowing for proper drainage of water away from the rails (which is why the stone is always sloped downward and away from track).
My personal choice is for fine ballast on HO track. I always liked the comparison of measuring the size of ballast against the size of a scale human hand. You can get your fingers around most real ballast (althought I understand that that might have changed in recent times). I also like the observation that some things don't scale well.

A review was made of the current American Railway Engineering Association (AREA) Recommended Practice for selecting ballast size. Pertinent excerpts from Chapter 1 - Roadway and Ballast are
• Ballast quality and ability to resist crushing forces (ballast degradation is the number 1 cause of ballast fouling) – Some railroads use different track modulus (u) values in design. For example, Spring u may be used for rail bending and ballast depth, but Winter u used for rail seat forces. Other railroads may use a single u value.
The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon.
