Tests are conducted to determine rail slippage for concrete ties, using the fastenings to check the slippage resistance anticipated in the design calculations. Test procedure is described and results are presented. It is noted that the values of rail slippage resistance for the AAR design clips for the Type E tie are generally more than the 2000 lb minimum for 5000 lb bolt tension, except those with vibration, which are only about 1000 lb. It is concluded that the measurements of rail slippage resistance obtained agrees reasonably well with those anticipated in the design of the fastening for the AAR Type E prestressed concrete tie. It is believed that a range of bolt tension between 10,000 and 5000 lb should be maintained with AAR clips until such time as service experience indicates that a change in these limits is warranted.
