@q3k @redford @mrtick These trains are like $15M USD each.

As costly and painful as it would be I'd put the OEM's CEO on 3-way while I phoned the CEO of a competitor and said "OEM1 just bricked my trains because they were gouging me on maintenance. You were runner up in the original bid, can you do better? If you can you'll have an order by end of week." if they tried this horseshit. Then explain to OEM1 CEO that they can expect their trains back as soon as I have replacement rolling stock.
