FASTENINGS

1. Spikes shall be started and driven vertically so that the head has full bearing over the base of the rail.

2. All spikes used in the 85-lb tie plates shall be 5/8 by 5 1/2 inches in dimension.

3. Outside spikes shall be on the north side of the tie, inside spikes shall be on the south side of the tie.

4. All curves shall be double spiked

5. Joint bars for the 72-lb rail shall be of the new head free design. No joint bars from the old main line shall be used since these are of the head contact design.

6. All bolts for the 72-lb rail shall be 7/8 inches in diameter. 7/8 bolts designed for 65-lb rail shall not be used as a substitute for these bolts.

7. Washers for all bolts shall be of the heavy duty size. The size of lock washers supplied at 19-A shall not be used since they are too light for a 7/8 inch bolt.

8. The nuts for the 7/8 inch bolts shall be applied with the beveled side facing away from the joint bars.

9. Joint bar bolts shall have one lock washer and one nut.

10. Bolts when tightened by the bolt machine shall be tightened to 25,000-lbs.

11. Center bolts shall be tightened first then the end bolts.

12. The stagger of bolts on the 72-lb rail shall conform to sketch 2. (I.E. the same stagger as on the 85-lb rail)

13. Rail anchors on the 85-lb rail shall be applied as the track is constructed.

14. 16 rail anchors per 39 foor panel shall be applied with two ties per panel box anchored, the remaining 12 anchors shall be used to prevent downhill creep.

15. Rail anchors shall be applied with the hook portion on the gauge side of the rail, or just opposite the way they were installed at 19-A and mile 76.

16. 60 ties in each direction from switches shall be box anchored, including the siding turnout.

17. 1/8 inch wood shims shall be inserted between each rail to provide for temperature expansion.

18. Care shall be observed that the rails are seated evenly in the tie plate bed. Careless installation frequently causes one end of the shoulder to be spiked under the rail. A broken plate invariably results. Hammering the plate to effect proper seating is destructive and undesireable.
