Thank you for posting these pictures from the Simms collection.
ReplyDeleteWhat is the reason for adding truss rods below the side frame of steel interurban cars, like those in this post? Did they have a tendency of sagging like wood cars, or do the truss rods serve a different purpose?
The earliest steel cars did have truss rods to prevent sagging, carried over from wood car design. The most immediate example would be Michigan Electric 28, which was built with truss rods. Those were removed when it was turned into a house, and still need to be replaced for authenticity. But the body hasn't started to sag yet.
DeleteThank you very much for the explanation.
