Exami-nation of the engraving will bring out additional interestingfeatures of this construction, among which the removableshoes for the journal-box columns should be noted. The carewith which this truck has been developed, and the experienceof the designer, warrant the expectation that it will be entirely. Steel Passenger Truck of New Car Truck Co. successful. A truck which will carry acar as smoothly as the present heavy pas-senger trucks and at the same time weighvery much less than they do seems to begreatly needed. The developments of ex-perience with Mr. Barbers design will bewatched with the greatest interest. Theoffices of the Standard Car Truck Com-pany are in the Old Colony and the outer columns are hinged so that wheels may betaken out. without raising the car, after the brace at the endof the frame is removed. The construction of the truck issuch as to transmit ad of the loads in a vertical direction bycentralizing all the stresses in a vertical plane and transmit-ting them to the center of the journals. The load from thebolster is transmitted through a casting to a shoe upon rollersresting upon a steel seat. This seat rests upon the center ofa strongly ribbed equalizer, the ends of which rest upon t
