Furthermore, Rail is saying that "human error is thought to be the main cause of a Caledonian Sleeper train running away through Edinburgh Waverly"
No surprises there then. But they do add something interesting...

So that might account for how the brake pipe was closed off from the loco. However this should have been noticed if the brake tests required by the rule book (listed earlier in this thread) had been carried out.
They also mentioned..

Which is right because a personal (static) brake test only requires the driver to observe the brake gauges moving up and down, it doesn't prove the brakes are working. What
really tells you what's going on is a running brake test, which looks for 'retardation' (a drop in speed). You both feel this in the seat of your pants & see it on the speedo. And
if a running brake test wasn't conducted, someone is definitely in the doghouse.
We continue to watch with interest.
