ABSTRACT: A full-scale impact test of a locomotive crashing into a highway trucking rig (tractor and trailer) loaded with two steel coils was conducted on a grade crossing at the FRA’s Transportation Technology Center (TTC) on December 18, 2002. This was the third of a series of locomotive crashworthiness tests conducted under Task Order 137. The rearmost steel coil was aligned with the right side collision post of the locomotive. An anthropomorphic test device (ATD, or test dummy) was placed seated on the floor in the nose of the locomotive, facing rearward with it’s back against the interior door. The impact speed was approximately 58 miles per hour. On impact, the trucking rig was thrown clear of the track and destroyed. The chains holding the coils on the trailer broke free and the rear coil struck the collision post, shearing the post just above the weld between it and the underframe. The coil continued into the cab destroying the windshield, control console, and cab floor. The ATD sustained severe damage including damage to the head, neck, left shoulder attachment, and skin.
