[quote user="samfp1943"] As someone who is 'just a railfan', and without any engineering skills; I do not understand this problem with building passenger railcars(?)........  Seems a simple enough task- build a car(s) to agreed specific designs........ If the test is no compliant, the manufacturer has an obligation to correct and make the product to the specifications agreed upon when the contract was entered into. [ Seems to be a fairly cut and dried process.  [/quote] What you describe is how the project should ideally work. The N-S PRIIA bi-level cars are good example what can go wrong. The project started with specification that contains a number of conflicting requirements like buffer load, weight limit, layout with requirements for locations of openings. N-S got the order as subcontractor of Sumitomo. The bi-levels were designed in Japan and built in Rochelle according to Buy American requirements. Though in the Finite Element Analysis successful the carbody failed the 800,000 lbs buff load test.  N-S tried far more than a year to correct their design before the lost the order to Siemens single level cars. It still disturbes me that N-S didn't find a solution and Japanese engineers don't give up easily. So there must have something in the specification they were not able to meet under any circumstances. And then the buyer needs cars desperately........... I expect that N-S payed a lot of damages.
