High Tensile Strength Plain Railroad Tie Plates as Track Fasteners
Brief introduction
A tie plate is a thick steel panel that sits between the rails and ties, or sleepers, on a standard railroad
track. Railroad tie plates are generally tapered at either end to improve stability and reduce torsion
and twisting along the rails. Rails installed with tie plates are better able to maintain their position,
which helps to standardize the width, or gauge, of the track along its length. Engineers and builders
use rail tie plates to extend the longevity of a new track installation, and to maximize safety for
passengers and railway workers.
