The title of this post, is the same as that of this article on the BBC.
This is the introductory paragraph.
Aberdeen’s fleet of hydrogen buses has been taken off the road due to a “technical issue”.
The technical issue appears not to be hydrogen-related, but with a mounting bracket.
Strange coming after CAF had bracket trouble with their trams and Hitachi had a similar problem with their trains.
Wrightbus, CAF and Hitachi haven’t been using the save dodgy Chinese supplier called El Cheapo Brackets have they?

Wrightbus, how do they know it wasn’t hydrogen, it could have been hydrogen embrittlement of a steel bracket 😉

That would have surely needed a hydrogen leak!

My last comment, I have to say was more said

When it became clear last year that multiple rolling stock manufacturers were having the same problems with the same components I was certainly beginning to wonder.

when I was at ICI in the 1960s, the department I was in, used to build infrared process analysers for use on the plants. They were high-tech optical and electronic components that were fixed to an optical bench, that was made to a high degree of accuracy. A two metre length of C-section steel beam was used. We found that the ones that were best were old rusty beams, that were decades old because the steel had all crystallised out. Obviously, they were ground flat and finished with a special paint, but we never had any problems with accuracy. I wonder, if these brackets are from new steel and they haven’t got their metallurgy right.

Possibly a mixture of trying to reduce steel usage (cost and weight) but not quite getting the engineering right, and cheaper or falsely supplied steel (from subcontractors).
Has been happening in commercial aviation too, one of Boeing’s other troubles is poor quslity subcontracted bracketry from Italy.
