Low Vibration Tie

• Secures 115 RE rail to a concrete track bed

• Controls vertical, lateral, and longitudinal rail movements

• Provides track noise and vibration isolation

• Electrically isolates rail from track bed

• Lateral adjustment of +/- 1 inch by 1/8 inch increments achieved through boot replacement

• Lateral adjustment of +/- 1/8 inch achieved through toe insulator replacement 

• Utilizes non-threaded left or right handed spring style clips 

The following are product assembly performance characteristics found by laboratory testing using industry standard test methods. The product performance stated below are reported as a per Resilient Tie assembly characteristics. 

• Vertical Stiffness – 140,000 pounds / inch deflection between loads of 4,000 to 12,000 pounds per unit assembly 

• Dynamic to Static Stiffness Ratio at 10 Hertz load rate - < 1.4 

• Lateral Load – < 0.150 rail head deflection with Vertical load of 14,000 pounds and Lateral load of 6,000 pounds per unit assembly. 

• Lateral Restraint - < 0.125 rail base deflection with Vertical load of 2,500 pounds and Lateral load at the rail base of 7,000 pounds per unit assembly 

• Longitudinal Restraint – approximately 2,500 pounds prior to rail slippage 

• Repeated Vertical and Lateral Load – 3 million cycles applied without unacceptable performance degradation. Loads applied as 10,000 pounds Vertical with 4,000  

• pounds towards field and 2,500 pounds towards gage. 

• High Voltage Withstand – resists 15,000 volts (DC) 

• Electrical Resistance – greater than 50 Mega Ohms at 750 volts (DC) 

The above performance characteristics are provided for informational purposes and are based solely on previous testing. Actual performances may vary from those stated above.
