General Instructions
1. Set handbrakes and wire or block them in place.
2. Place and wire-tie gearshift levers in the neutral position.
3. Use an applicable-sized come-along mechanical hoist, or equal tensioning device, to tension wire rope.
4. See General Rules 1, 2, 3, 4, 5, 7, 9, 11, 12, 13, 14, 15, 19, 19A, 19B, and 19C in Section 1 of the Rules Governing the Loading of
Commodities on Open-Top Cars and Trailers, published by the Association of American Railroads. These rules provide applicable
guidelines and are mandatory in application.
5. Properly tighten the wire rope clamp nuts by using a proper sized torque wrench. After the nuts have been initially tightened,
strike the “U” side of each clamp several times with a hammer to ensure proper seating into the dead end line, repeatedly and
alternately tightening each clip nut to acquire final torque.
NOTE
Use a staggered nailing pattern to nail lumber or laminated lumber to the floor or a railcar.
Adjust the nailing pattern for an upper piece of lumber, as required, so that a nail for that piece is
not driven into or immediately adjacent to a nail in the lower piece of lumber.
