Application Criteria of Track Bolts

According to basic rules and rail standards, each rail joint needs to be bolted with at least two bolts in each rail tightened to generate approximately 400 foot-pounds of torque, which approximately develops between 25,000, and 30, 000 pounds of tension force in the bolts.

• Bolts in use have to be in the proper size and tightly in place.
• Bolts have to be installed with AREMA spring washers whereas the nuts have to be installed against the spring washer.
• Bolts have to be installed and the nuts have to installed alternately on the inside and outside of the rail.
• When bolts and joint bars are moved away, the joint area of the rail and the contact surface of the joint bar have to be cleaned and the joint bar and the bolt threads have to be lubricated.
