Staying on Track | Civil + Structural Engineer magazine

Ballast is another important asset of a railroad. According to UFC 4-860-03, there must be adequate ballast to restrain the track laterally, longitudinally, and vertically under dynamic loads; and to distribute the load of the track and trains to prevent overstressing the subgrade. The railroad consists of tons of ballast.
