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)).
