Comparison of Ballast and Ballastless Tracks Master Thesis

2. Characteristics of ballast 2.1. Production of ballast What is track ballast? The term "ballast" comes from a nautical term for the stones used to stabilize a ship. Track ballast is a part of the track in which the sleepers are embedded together with the rails. It should distribute loads from contact points into an area, big enough to

Track (rail transport) Wikipedia

The track on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade enables trains to move by providing a dependable surface for their wheels to roll upon. For clarity it is often referred to as railway track (British English and UIC

Ballastless track Superstructure :: Trackopedia

The negative impact of the ballast on the service life of the track led to initial designs of ballastless track. The ballast is replaced by sublayers of concrete or asphalt which, unlike ballast, have no or only slight plastic deformation. The lack of elasticity of these layers is compensated by the conscious use of elastic components. Only in

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.
