Broken loco driver spokes

[NW Mailing List]

It would be quite an event for driver spokes to fail. They are part of a 
casting that is held in compression by the tires. Almost seems a tire 
would have to come off to expose the spokes to forces that would break 
them. That said, a poor casting might fail, and we should note that some 
early locomotives had wooden or composite spokes that were far weaker 
than castings.
