The use of single or double shoulder tie plates makes a more stable track and greatly lengthens the life of wood ties. Punched and sheared from hot-rolled steel sections, tie plates provide proper cant, uniform bearing surface for the rail and better load distribution to the ties. They hold the rail to gauge, providing more uniform wear to rail head and protect against undue wear to ties.
Tie Plates fasten the rail to the tie and maintain gage and alignment of rails in track. New double shoulder tie plates are available for 5-1/2″ and 6″ base rail and are manufactured according to AREMA specifications. Used double shoulder tie plates can be supplied to fit most rail bases. New single shoulder tie plates are no longer available, but they can be furnished as used and will fit any rail section.
