Open publisher page 5 citations

Abstract

This paper presents design and construction details of two types of slab track installed at the Facility for Accelerated Service Testing (FAST), near Pueblo, Colorado. Direct fixation slab track (DFST) and independent dual block track (IDBT) were installed on a 5-degree curve with 4-inch superelevation. The slab track test section was 500 feet long, consisting of 250 feet of DFST and 250 feet of IDBT. The slab track test section was designed to support 39-ton axle load train operations, while maintaining track geometry for high-speed track standards.
