Abstract: Disclosed is a utility tool assembly for use with a handbrake wheel found on most railroad cars and locomotives. The handbrake utility tool assembly includes a dual directional hook head and a slot formed within the head for engaging the air brake retainer valve. The handbrake tool in a further embodiment includes a telescoping handle with a quick connect/disconnect handle assembly for engaging a locking mechanism as the inner handle is extended. The tool includes an anti-flagging or anti rotation locking mechanism so that the tool's head does not rotate uncontrollably.
