Analysis of Colliding Vehicle Interactions for the Passenger Rail Train-to-Train Impact Test
The video shows the impact of an initially moving cab car led train with an initially standing locomotive led train at 30 miles per hour, and without and with an animation of simulation results overlayed on the test video. The first view shows the cab car coming in from the right and impacting the standing locomotive, which is on the left. The cab car initially crushes, and then the impact end starts to rise. The end of the cab car continues to rise as the cab car crushes, and the cab car overrides the locomotive. Eventually, the cab car overlaps the locomotive by approximately 20 feet. Once the locomotive-led train is moving faster than the cab car led train, the end of the cab car slides off the locomotive and falls to the ground. There is very little structural damage to the locomotive during the impact. The second view shows a closeup of the cab car impacting the locomotive, from just before the instant of impact, until the cab car has climbed the locomotive. The third view shows the same test video as the second view, but with the animation of the simulation results overlayed. The animation of the simulation results closely matches the test video for about eight feet of crush of the cab car.
