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 locomotive) 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.
