  • Method for manufacture of railway or transit car shell subassemblies
    Patent number: 5499451
    Abstract: A method of manufacturing railway or transit car body panel subassemblies using frame component members, such as carlines 10, side posts 86, window sills 88, frame members 102, floor sills 116, roof sills 104 and floor beams 114. Each frame component is formed with reference holes integral therewith at predetermined locations. Frame component templates having corresponding jig pins for interfitting engagement with the reference holes are used to confirm dimensional tolerances regarding the size, shape and silhouette of each frame component unit. Subassembly fixtures having jig pins for interfitting engagement within the same reference holes are used for holding various component members in position for welding or fabrication of side wall, roof and floor subassemblies. Subassemblies are then fastened together to form a railway or transit car body shell of uniform dimensional size and shape.
