Introduction to Railroad Track Structural Design

• 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

It also helps with drainage, so rain water can drain away rather than pooling, and with preventing vegetation growth, which could destabilise the track and be a hazard for anyone working on the railway.
