Abstract: A railway truck includes a pair of pivotable side frames connected by a pivot assembly which maintains the side frames in tram while still permitting equalization. Springs are connected between a car body and the side frames to provide equalization for the wheels on the truck. The springs also serve as the load transmission path from the car body to the side frames.

Abstract: A panel of a trailer is adhesively bonded to a plurality of horizontal and vertical support rail structures which are secured to the main body of the trailer. Each of the structures include a pair of rail elements through which loads are transmitted into the panel by means of adhesively bonded joints between edges of the panel and the rail elements to provide sealing and support for the panel.

Abstract: An emergency release handle is pivotally mounted within an interior wall of a railcar and connected to pull a cable under emergency conditions to actuate a mechanism, such as a mechanism to open a door. The handle is normally maintained inside the wall by a flexible guard plate and retaining screws passing through screw holes which are connected to the wall surface. Manual gripping means is connected to the handle to permit a person to grip it and pull to cause the flexible guard to flex and pass the retaining elements and permit the handle to pivot and pull the cable.
