LONG ISLAND RAIL ROAD CONCRETE SLAB TRACK

During the last 9 years, the Long Island rail Road has embarked on various concrete slab track projects to provide a solution to problems of costly track maintenance. The conventional track consists of wood cross ties and ballast, whereas the slab track entails a continuously reinforced concrete slab supported on an asphalt-treated subbase and compacted subgrade. Some of the considerations in selection of concrete slab track were availability of technology, faster operating speeds, reduced maintenance costs, limited access in yards and tunnels to track maintenance equipment, more reliable track structure, and improved ride quality. This article discusses advantages, design features, construction methodologies, field testing findings, and overall review of the slab track projects.
