Disclosed is a rail supporting assembly for supporting a contact rail of a railway system that includes a base, a rail support head positioned relative to the base, and a support member comprising a dielectric phenolic material coupled to and positioned between the rail support head and the base to thereby support and insulate the contact rail. The support member includes a fracture area to facilitate fracturing of a sidewall of the support member when a fracturing force, such as a electrical arc event, is applied to the support member. The support member preferably is coated with a varnish to prevent absorption of water by the support member.

Modular easy load container

A modular assembly for an indoor shutter includes fully functional louvers and is assembled from extruded and/or injection molded plastic components designed to provide complete symmetry to the assembly, both side-to-side and bottom-to-top. Two identical bottom (or top) half frame members are secured together with a pair of connector members. A pair of side rail channels are slid down over the ends of the bottom frame members and enclose the connector members therein. A pivotal louver and a pair of louver supports are alternately slid into the side rail channels with the louver pivots captured between cylindrical notches on the upper and lower faces of vertically adjacent louver supports. The top frame member is connected and closed off in the same manner as the bottom frame, utilizing identical components. Common uniform control of the position of the louvers is provided by a control arm disposed within the open interior of a side frame member and completely hidden after the shutter is assembled. The control arm interconnects short crank members attached to the ends of the louver pivots such that manual rotational movement of one louver about its pivots effects common rotational movement of all of the louvers in the shutter.
