The Track Laying System, used on Amtrak's Northeast Corridor Improvement Program, represents a significant change in track work methods and maintenance philosophy. The TLS system, consisting of approximately 30 pieces of equipment and requiring 170 workers, renews all components of a track structure in the course of passage over it, including the roadbed beneath the track. As in Europe, where TLS machines originated and where they are used extensively, the goals are increased productivity, improved ride quality, and enhanced maintainability. Heart of the concept is the P-811 Track Laying Machine, or Valvaterre System, developed in Italy.
