NW SHAPES TRACK PRACTICES FOR HEAVY TONNAGE, MUCH CURVATURE

The detrimental effects on rail and other track components produced by unit train operations with 100-ton cars and six-axle locomotives are compounded on Norfolk and Western by heavy grades and curves. Wide gauge is countered with large tie plates, more spikes and reduced superelevation. Rail wear is lessened with rail lubricators and hardened rail on curves. Ballast requires frequent cleaning and high quality ballast is essential. Welded rail is used extensively and successfully. Track geometry and ultrasonic cars have major roles in producing data for track maintenance planning.
