摘要： A self guarded frog copper weld fixture has a rail form and a pair of transverse locator arms. The rail form is configured to abut with a damaged rail frog and define a proper repaired geometry for the rail frog. A pair of locator arms transversely and vertically locate and secure the rail form against one of the rails of a damaged rail frog, by applying an opposing force against a second one of the damaged rail frog rails. Any wear will present as small gaps between the rail form and rail frog. The transverse locator arms are pivotal with respect to the rail form, and so may be rotated from transverse to the rail form to align longitudinally for compact transport or storage, and may also be reversed to allow either one of the longitudinal vertical side edges of the rail form to be abutted to the rail frog.

摘要： A control system executes preliminary biasing processing including controlling a guide wheel drive unit to bias a guide wheel in a direction from a first position toward a second position while the guide wheel is at the first position and is in contact with a first-side surface of a branch guide portion from a first side in a width direction before entering a switching area, and allows the guide wheel to pass through the switching area while executing the preliminary biasing processing.

摘要： A nose type rail member for a crossing member applied to a turnout or wayside switch system on the ground for a train and the like, is made of high carbon steel material containing 0.70 to 0.82 wt. % of carbon. The rail member is constructed by a pair of rail parts, which have a concave at a side of the middle support part. A backing plate is made of the same material as the rail member, or a steel material having a less carbon content than that of the rail member, and is held by a pair of the opposite concaves. A pair of the head portions and the base portions at a side thereof are joined by means of electron beam welding, and the joined rail member is subjected to S.Q. heat processing; whereby at least a wheel tread of the rail member becomes a homogeneous and fine pearlite structure.
