Abstract: A bulkhead fitting has a partially assembled configuration and a fully assembled configuration on a bulkhead. The bulkhead includes an interior surface that define a hole. The bulkhead fitting includes a fitting body having a head portion and a shank portion. The shank portion includes a threaded portion, a relief portion, and a locking portion. The locking portion includes a tapered locking surface and a cylindrical locking surface. The locking surfaces prevent rotation of the fitting body and retain the fitting body in the interior surface when the fitting is in its fully assembled position and during assembly.

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.
