Many companies create a special corporation for big projects, so the main company is shielded from the big law suits. By getting into litigation now, CAF stops all work, lays off the entire staff, waits out the years until the litigation is settled. If CAF ends up with owing money and being in an impossible situation, they just exit by cutting off the corporation created just to build the Amtrak order. Amtrak ends up with a win in court, but no cars built, and the process has to start over so they have lost everything invested to date. To me, all Amtrak can do is work with CAF to hep them move forward.
