New Devec LINK SIDE BEARING TRUCK It is claimed by a number of experts on car design that it isadvisable to abandon the loaded center plate scheme in car con-struction, thereby eliminating truck bolsters and center plates,and to carry the load at four points directly to the truck sideframes. These men state tliat it is useless trying to balance a. load of 100,000 to 200,000 lbs. on two central points at each endof the car and on an area so small that a lubricant is hard toretain even were they lubricated. This feature, as well as foravoiding all trouble with side bearings, has led to the design of
