h. Salvaging Rail. During track reconstruction, the existing rail and other track materials can often be
salvaged for use at other locations on the installation, stockpiled for future construction projects, or sold
on the open market as used material. Lightweight rail, defective rail, and other track materials not
suitable for use in track reconstruction on the installation or for resale on the open market should be
disposed of as scrap or reroll material.
16. OTHER TRACK MATERIAL.
a. Definition. Tie plates, joint bars, bolts, spikes and other miscellaneous hardware used in track
construction are commonly referred to as other track materials (OTM).
b. Tie Plates.
(1) Tie plates vary in length and width. Most sizes are suitable, as long as the spike hole punching
(or distance between the shoulders - for double shoulder plates) matches the width of the rail base. For
double shoulder tie plates, the distance between the shoulders will be at most 1/8 in. larger than the rail
base width. On single shoulder plates, the spike holes on the gage side (opposite the shoulder) must
keep the inside face of the spike within 1/8 in. of the rail base when the opposite edge of the base is
against the shoulder. (See figures 6-21 (a) and (b)).
