Secfion 8~ Plan of the Curved Bumper Castings and Articulating Link traction stresses are transmitted from the frames of one truckunit to those of the other through the bumper beams, withoutimposing any stresses upon the cab structure other than thosedue to its own inertia. The inner bumper beam of each truck unit is a steel cast-ing of box section, the vertical faces of which are circulararcs with radii equal to the distances from the center of thecab center pin bearing. The two castings are thus in rollingcontact with each other as the angularity of the center linesof the two trucks changes, due to track curvature. Sup- detail the arrangement of the apparatus in the cab. Single-phase current at a potential of 11,000 volts is collected by trolley, thence following a path through an oilcircuit breaker to the primary of the transformer from whichit is led to the framework of the locomotive, the circuit beingcompleted through the rails to the substation.
