LNER breach notice published by DfT

[jayah]

You don't want one bad month causing a breach, but if standards have slipped so far the annual average is unacceptable then reason needs to be focused on.

Obviously will be much harder to fix a series of unusual events than if it is same trains every week causing problems.

You don't want standards to slip so far and it still takes 5 months before any action is triggered.

Taking one month or the previous twelve are equally flawed.
