Application Criteria of Track Bolts
According to related rail standards, each joint needs to be bolted with at least two track bolts in each rail tightened to approximately 400 foot-pounds of torque which develops between 25,000, and 30,000 pounds of tension in the bolts.
Track bolts in use have to be in the proper size and tightly in place.
Track bolts have to be installed with AREMA spring washers whereas the nuts have to be installed against the spring washer.
Track bolts have to be installed and the nuts have to installed alternately on the inside and outside of the rail.
When track 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.
Safety standards require that on operation are permitted over rails where all track bolts are missing or ineffective
