The difference is: - there's a proper registry of who is responsible for maintenance of the train, including chain of liability. Crucially, the vendor wasn't in it for the affected trains - they'd only be liable if design issues were found. - maintenance companies was appropriately certified and verified - we're talking professional MRO, not random workshop - owners of the trains were also registered as responsible parties for maintenance and repair - vendor was supposed to provide documentation that would allow such a workshop to perform maintenance and repairs up to P5 (largest scale) maintenance - vendor never disclosed lockouts they implemented, thus committing fraud at the very least.
