Dynamic Testing of a Non-Proprietary, High-Tension, Cable End Terminal System

Two bogie tests were conducted on a high-tension cable end terminal to evaluate the performance of a new design. The main goals of the new design were to promote quick cable release times, to retain the cable release lever during impact, to sustain no permanent deformation, to have a stub height less than 4 in. (102 mm), and to provide more clearance around the cable anchorage fittings. In test no. HTCT-2, a 1,961-lb (844-kg) bogie vehicle impacted the cable end terminal at a speed of 52.8 mph (85.0 km/h) and an angle of 0 degrees, which is end-on to the terminal. The cable release lever was retained with the rotational joint, and three of the four cables released by 18 ms. However, the second cable did not release from the cable anchor bracket as desired. Minor permanent deformation was found in the cable release lever. In test no. HTCT-3, a 1,853-lb (841-kg) bogie vehicle impacted the cable end terminal at a speed of 51.1 mph (82.2 km/h) and an angle of 25 degrees. All cables released from the cable anchor bracket and the cable release lever was retained. However, the cable release times were later than desired and likely contributed to the bogie vehicle becoming airborne and subsequently rolling. Significant permanent deformation was found in the cable release lever.
