That sounds familiar to me too. IIRC there were questions about how the revision was handled. If my shaky memory is correct it was a bit squirrely, something to the effect that Kawasaki had the optimum bid based on a combination of cost and build quality, but Rotem came in with a lower final cost if the build standards were relaxed. Which they were ... and we saw what happened.
Requiem for it's/its, your/you're, than/then, less/fewer. They were once such nice words with such different meanings...
