WMATA has really had quality problems.  To digress the Honolula problems are another. Wonder if there is any connection between the two ?  Either contractor or maybe sub contractors ?

Until I get a link to what the NTSB actually said this 'noncompliance with specifications' hooey means, I'm not bothering with further "news source" coverage.

And I'm already tired of seeing Russell Quimby quoted as an NTSB expert.

Someone get the docket number and post it here.

is it a coincidence ?.  Now reported guage wheel problems for WMATA.  Two very separated agencies.  Of course that is just a preliminary NTSB report.

Absent specific technical information with actual engineering detail content (which might as well be rocket science to most of our fifth-column fourth estate) it is impossible to determine if there is any connection.

I do find it interesting that only one axle was mentioned as being 'out of compliance with specifications' (whatever the hell that jargon actually was meant to connote) and the inspection follows a report of what sounded highly like inability to disengage a parking brake (or at least to disable a parking-brake application warning) some time before the 'incident'.  It seems 'not illogical' to me that brake friction leading to heavy wheel overheating followed by heavy lateral shock or tight curvature might cause slight displacement of gauge on the braked axle.
