• 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 .
Ballasted track varies considerably, with rail pad stiffness being a key parameter. The low fastener stiffness on slab track is the main reason for its higher noise levels, with absorption of sound by the ballast accounting for only about 1dB. Treatments for noise from slab track include absorptive panels and rail dampers.
