Yup, I'd missed that he had rung the electrification control room (and
hopefully waited for the OK though we don't know that either !)

His words reported in the Daily Telegraph:

"Once I was informed the power was off I went onto the track and
removed the trolley ... Later that week I was told ... that the power
hadn't actually been turned off".

Shouldn't part of the safety process be putting a shorting bar down to
make sure that the power was off?
