Abstract: A method for providing overspeed protection for a gas turbine engine having an engine shaft includes monitoring, via an overspeed protection system, a torque of the engine shaft. The method also includes determining, via the overspeed protection system, at least one additional condition of the engine shaft. Further, the method includes determining, via the overspeed protection system, an overspeed condition of the gas turbine engine when the torque of the engine shaft drops below a torque threshold and the at least one additional condition of the engine shaft is indicative of the gas turbine engine being in an operational state. Thus, the overspeed condition is indicative of an above normal rotational speed of the engine shaft. In addition, the method includes initiating a shutdown procedure for the gas turbine engine in response to the determined overspeed condition to reduce the rotational speed of the engine shaft.

Abstract: A skate for conveying components into a monocoque locomotive. Portions of a monocoque locomotive platform are not accessible through a roof hatch. To move a component onto such portions of the platform, a skate assembly having an integral clamp assembly is attached to a leg portion of the component, the component is lifted onto the platform through a roof hatch, and the component is rolled on the skate rollers to the desired position on the platform. A jacking device integral to the skate assembly is then used to lift the component for removal of the rollers and for holding the component at a desired height for attachment to the locomotive.

Abstract: A window assembly for a locomotive is sealingly disposed in an opening within the sidewall of the locomotive and attached to the sidewall to allow limited relative movement of the window assembly with respect to the sidewall without disrupting the seal.
