A guardrail for a walkway of a machine includes a vertical channel post having an end wall and side walls forming an open channel. The vertical channel post may taper in the side-to-side and fore-aft directions as the post extends bottom to top. The vertical channel post may also transition from a generally rectangular cross-section near the bottom to a more rounded cross-section at the top. Curved top notches at the top of the vertical channel post allow a top rail of the guardrail to rest on top of the post and be attached. Intermediate notches along vertical edges of the side walls receive an intermediate rail of the guardrail. The top notches and the intermediate notches are arranged so that the top rail and the intermediate rail may be vertically aligned and parallel to each other and to the walkway enclosed by the guardrail.

A draining system for draining fuel from a fuel tank is disclosed. The fuel tank includes a holding chamber for holding fuel and a fill port assembly for adding fuel to the holding chamber. The fill port assembly includes a fill port passageway in fluid communication with the holding chamber and a valve system for regulating a flow of fuel through the fill port passageway. The draining system includes a coupling member having a drainage passageway. The coupling member is detachably connected with the fill port assembly. An actuating member selectively actuates the valve system to permit fuel to flow from the fill port passageway into the drainage passageway. An outlet conduit is in fluid communication with the drainage passageway such that fuel can flow from the drainage passageway into the outlet conduit. A flow regulating member is configured to regulate flow of fuel through the outlet conduit.

A thermal energy storage transfer system that is adapted to transfer heat from an electronics enclosure. The thermal energy storage system includes a thermal energy storage unit that is positioned within the electronics enclosure. The thermal energy storage unit contains a phase change material that stores heat created by electronics stored within the electronics enclosure and transfers the heat to outside of the electronics enclosure by use of a heat pipe and condenser.
