The weight of a single length of steel rail used in railway tracks varies considerably, primarily depending on its size and intended application. A common measure used to describe rail size is its weight per yard. For example, a rail weighing 115 pounds per yard means that a three-foot section of that rail weighs 115 pounds. Rail weights can range from light rails used in smaller railways or industrial settings, weighing as little as 50 pounds per yard, to heavy-duty rails exceeding 140 pounds per yard, designed for high-speed and heavy freight lines.
Knowing the weight of a rail is fundamental for various aspects of railway engineering and operations. It directly impacts track stability, load-bearing capacity, and overall infrastructure durability. Historically, heavier rails were adopted as train sizes and speeds increased, demanding stronger tracks. This information is crucial for calculating material needs, logistics, and associated costs in construction and maintenance projects. Furthermore, accurate weight estimations are vital for ensuring the safe and efficient operation of the railway network.
