Abstract: A method for forming a smooth interface between a weld cap and an adjacent base metal utilizing ultrasonic impact treatment. The method improves the geometric profile of a weld while imparting a compressive residual stress layer on the weld metal and base metal thereby alleviating the tensile residual stresses imparted to the metals during welding. The contouring process does not remove material, as in grinding, but plastically deforms the surface being treated producing a densified surface, in turn providing a smooth weld cap and base metal surface finish without the loss of base or weld metal thickness.

Abstract: A diesel-electric locomotive has two separate engine systems, including a large engine system and a small engine system. The power output from the separate engine systems may be combined to power the locomotive's traction motors. When the locomotive requires low power output for propulsion, only the small engine system is used to power the traction motors. When the locomotive requires higher power output, only the large engine system is used to power the traction motors. When the locomotive requires maximum power output, the small and the large engine system may both be used and their power output combined to power the traction motors. Also, a unique control strategy maintains a smooth delivery of power to the traction motors in the event that one engine shuts down or starts as a result of a change in the commanded power output of the locomotive.
