I like the caption to the video on the above page - "Boris Johnson's
no strike deal has never materialised" - no sh*t! And it always seemed
so likely... ;-)

Anyhow, infrastructure staff appear to be walking out at 5pm (is this
just the ex-Metronet lot?), with drivers, signallers and station staff
following at 9pm.

There's also strikes planned by TSSA at infraco Tube Lines (now TfL
owned) on Tuesday 7th, and at Alstom who maintain the Northern and
Jubilee line trains with a 24hr strike planned to begin on Sunday 5th
at 7pm.
