Just a quick note to let you know that HMRI have finally gotten
round to publishing their final report into the Chancery Lane
derailment. It can be found, as a PDF, on the HSE website. [1]

4 pages? Is that it?

HSE seem to have had an outbreak of common sense. All the detailed
actions that arose from the derailment were contained in the LUL report,
though that seems to have disappeared from the TfL site.

I was particularly pleased to see that HSE is taking a sensibly balanced
view about the need to consider consequential risks when taking
safety-related decisions. Here's the relevant passage, which
unfortunately omitted the initial "If" in the web version of the report:
"[If] line controllers were required, for safety reasons, to take trains
out of service in the event of unusual noises, the consequence would be
to withdraw more trains than at present, increasing consequential risks
from station and train overcrowding due to service disruption. In simple
terms, the line controller has no way of knowing whether a report of a
noise from underneath a train is a safety-related problem or not, and to
require them to withdraw every train making noises would very likely
create more risks than it would avoid. It would not be reasonable to
expect LUL to respond to unusual noises in this way, and LUL would be
correct to consider the creation of additional risks when deciding what
would be a reasonably practicable response."
