Ballast or slab

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
