Some butterfly valve has failed, and it's a recurring failure, happening

in on their rest days to handle the crisis. The valve is rumoured to be
connected with the doors. There's no mention of this on TfL's site.

Presumably that's the reason the Picc is part-suspended this evening, "due
to a temporary shortage of train operators"?

Do you know what's the consequence of the butterfly valve failing?

If it is the butterfly valve (the one that controls doors on each car,
right?) that has failed. Then why the big ordeal?

The "butterfly cock" as I knew the term was the switch on the side of
trains that allow doors to be opened in an emergency.


Not even an emergency. I've seen them used when a driver wants to access
the car and doesn't feel like going through the cab.

It seems there has been a fleetwide inspection, as is normal, and LU
are saying it was an isolated incident. Seems the drivers from RMT and
ASLEF are not reassured. RMT are alleging a series of fleet problems
over the last year.

Why have we not heard more about this, however?
