Can we keep this to friendly debate? It gets somewhat ridiculous. The bus expired twice in a day, therefore Arriva failed. Whatever the circumstances, it broke twice, same reason or different reason. They have to keep buses moving to make profit as they are a business. A vehicle that stops working correctly twice in the same day is not a roadworthy bus at all. They won't send it out intentionally in a dangerous condition, but will push the limits of acceptability to keep it moving and making them money. 

Thank you.

So is every break down now entirely the fault of the company that operates the vehicle? 

When it was allocated in the morning, it wouldn't have been done so with the knowledge it would break down. Preventative maintenance can only go so far. Equally, when it had been fixed, whatever that fix involved, it would not have been sent out if they thought it would fail again.

Would a quick fix sort out the issue temporarily until fitters a) have time to sort it properly. B) a non-essential part is sourced. C) pvr requirements and pressures from management to get the vehicle out on the road has decreased?

Could that temporary fix then fail?

Was thinking about this yesterday, it seems as though the bus didn't need towed into the depot, and some fix was evidently carried out otherwise buzzers etc would still have been going off on the drive to wherever it started it's next journey, and until it broke.

Could they have patched it where it broke down, got it to the depot for a look and further repair. Then, when it was sent out again, either a similar fault manifested itself, or there was a more underlying reason that was causing the part(s) to fail?

If there was an underlying reason, that could result in a problem that can be caused by 15 other things, which has similar symptoms to a more common cause, then the repair would never work.

Again, like your post, all hypothetical...
