| Abstract | Previously developed computer models (see Volume 1) are used to carry out additional calculations for evaluation of road freight locomotive crashworthiness. The effect of fewer locomotives (as would be expected after transition from DC motor to higher-traction AC motor locomotives) is investigated and found to benefit cab crashworthiness to the same degree as would incorporation of high strength collision posts in head-on collisions at 30 mph closing speed. The effects of cab structure improvements are also investigated for higher closing speeds. The combination of high strength collision posts with an interlocking anticlimber appears to preserve survivable cab volume at closing speeds up to 45 mph, as compared with 30 mph for a structure meeting the minimum current industry specifications, in a head-on collision when override occurs. For closing speeds of 60 mph and greater, some type of crash refuge would be required to protect the crew from severe injury or death due to secondary impact with cab interior fixtures. |
