In the foregoing description of a car adapted to resist theshocks experienced in sidewiping, derailments and collisionswe have naturally illustrated and described the design ofcar which we have ourselves evolved while guided by a closestudy of the collection of photographic records of accidentswhich we have been accumulating for a number of the cable system of reinforcement can be incor-porated in any adequate design of vestibule end and bodyend construction. I, however, believe that a car embodyingthe strong superstructure, with strong vestibule and body endconstruction as outlined above is particularly well protected. Reinforced Body End with Cable Loops and the ultimate resistance of the main cables be example, in some of the complete telescoping cases illus-trated the initial resistance offered by the vestibule and thebody end construction of the invaded car was inadequate toprevent penetration. The secondary resistance offered by theroof structure and the interior fittings was negligible as com-pared to that which would have been afforded by wire cablesof 2,000,000 lb. (1,000 tons) capacity which would havechecked the invader at or near the point of entrance. It ismy opinion, that in cases of extreme violence, and before thevestibule structures have been completely compressed, thethrust transmitted to the underframe of the invaded car,through the medium of the cables, will be sufficient to impartmotion to the standing train and thus dissipate a large pro-portion of the energy of the collision. We are all familiar with shock absorbers in daily use, su
