Abstract: An apparatus for ventilating the cabin of a locomotive wherein the ducts serve both a ventilating and a structural function. Horizontal duct provides support for floor in place of one or more of the regularly spaced joists. Horizontal duct may include stringers recessed into sound absorbing insulation within the duct. Vertical duct is formed in part from a portion of a wall of the control compartment of the locomotive cabin, thereby eliminating the need for separate wall sections. The space saved by using such structures for dual purposes may be used to increase the cross-sectional area of the ventilating apparatus, thereby allowing the speed of fan to be reduced to provide the desired ventilation at a reduced level of sound.

Abstract: A locomotive assembly having a longitudinally extending platform and attached sidewalls with a frontal nosepiece extending about a front portion of the platform. The locomotive having a connection device for connecting components to hollow supports in the sidewalls without deforming the sidewalls, a bulkhead with an attached portion for preassembly components thereon before insertion between the sidewalls, a window assembly sealingly disposed in an opening within the sidewall and attached to the sidewall to allow limited relative movement without disrupting the seal, an enclosed headlight assembly flush mounted in the nosepiece with air circulation to prevent overheating within the assembly and an integral collision assembly for transferring collision forces to the platform.
