Railroad ballast is the uniformly-graded aggregate between and underneath railroad ties. The purpose of ballast is to provide support for the heavy loading applied by trains. New ballast contains significant void space between the aggregate. As ballast ages it is progressively fouled by fine-grained material that fills the void space.

Ballast cleaning extends the period before ballast replacement. However, eventually, perhaps after a 20–30-year service life encompassing 10–15 tamps and a midlife ballast clean, the trackbed performance becomes so poor that it requires complete replacement, i.e., renewal. During renewal, the now life-expired and fouled ballast is dug out and replaced with fresh

Ballast used on short lines is often of a lesser quality than what is seen on mainline railroads, and can be sourced more easily from the line's local area. Depending on the region, this can produce some very different appearances in color, combined with the fact that the ballast is allowed to weather for long periods of time before being replaced.
