Abstract: The invention may be described as including a switch guard casting, a switch guard assembly for a railway intersection, as well as a rail intersection design and a switch guard assembly therefor.

Abstract: A crossing panel includes a pair of intersecting rails, a pair of crossing line rails, a plurality of railroad ties supporting the crossing line rails such that the crossing line rails are angled upwardly from a base elevation toward the respective main line rail and terminating such that a tread bearing surface of each crossing line rail at its terminal end is at a height above the crown of the intersecting line rail, an external frog casting being aligned with and secured to the terminal ends of the crossing line rails and having an external frog tread bearing surface substantially above the crown of an intersecting line rail, and transitional guide castings disposed between the intersecting rails and respectively aligned with the crossing line rails. The transitional guide castings are substantially horizontal, and each has a crown maintained at a height sufficient to maintain a railcar wheel of a train wheel set above the intersecting line rails.

Abstract: The invention may be described as including a crossing panel assembly for a railway intersection, as well as a rail intersection design and a frog casting therefor. The present invention may be used for single and multiple crossings as will be appreciated from the description and drawings. The invention may be described as including a crossing panel assembly for a railway intersection, as well as a rail intersection design and a frog casting therefor. The present invention may be characterized as a frog containing panel system assembled with an array of castings that form a full flange bearing crossing to provide a rail intersection.

Abstract: The invention may be described as a rail bridge joint, associated guard plate assembly, and a bridge assembly incorporating same.

Abstract: A rail joint bar for use in an insulated lap joint assembly includes a longitudinal extending body defining a plurality of holes therein for receiving fasteners. The body has a first end and a second end positioned at opposite ends of the body relative to a longitudinal direction of the body. The body is bent forming a first portion adjacent to the first end, a second portion adjacent to the second end and spaced from the first portion in the longitudinal direction, and an intermediate portion defined therebetween and positioned between the first and second ends. The first portion and the second portion are substantially parallel to each other and, and the intermediate portion of the body is configured to accommodate an increase in thickness of a web section at a point where two railroad rails are joined.

Abstract: The invention is a guarded rail section for a movable bridge rail joint, the arrangement comprising: (a) a gage side guard plate having a gage side guard plate interior surface, (b) a field side guard plate having a field side guard plate interior surface, the gage side guard plate and field side guard plate defining a rail channel; and (c) a rail portion disposed in the rail channel, wherein the gage side guard plate interior surface defines an insert channel along its top portion, and there is provided a top portion insert removably attached into the insert channel.

Abstract: A method and apparatus for providing simultaneous enhancement of transmission loss and absorption coefficient using activated cavities is presented. A layer of material is provided, and a backing plate having a plurality of cavities on the top surface of said backing plate, is disposed adjacent a top surface of said layer of material. A screen is disposed along the top surface of said cavities on said backing plate and at least one cavity includes an actuator disposed within the cavity and a control system receiving a signal from the microphone and receiving a signal from the accelerometer and providing a drive signal to the actuator to provide an acoustic output to provide simultaneous insertion loss and absorption which serves to minimize a linear combination of the signal from the microphone and the signal from the accelerometer.

Abstract: A crossing panel includes a pair of intersecting rails, a pair of crossing line rails, a plurality of railroad ties supporting the crossing line rails such that the crossing line rails are angled upwardly from a base elevation toward the respective main line rail and terminating such that a tread bearing surface of each crossing line rail at its terminal end is at a height above the crown of the intersecting line rail, an external frog casting being aligned with and secured to the terminal ends of the crossing line rails and having an external frog tread bearing surface substantially above the crown of an intersecting line rail, and transitional guide castings disposed between the intersecting rails and respectively aligned with the crossing line rails. The transitional guide castings are substantially horizontal, and each has a crown maintained at a height sufficient to maintain a railcar wheel of a train wheel set above the intersecting line rails.
