Wednesday, 1 October was not a good day for London Underground.
Paddington signal failure about 0700 and "a person on the line" to
Hammersmith (Hammersmith & City) about 1100. Does that mean "one under"?

A train failure at Tottenham Court Road before 0700 resulted in no
Central Line service between Liverpool Street and Marble Arch until
about noon.
Alternative reports of emergency engineering works made me guess the
failed train hit something. Loss of the Central line seemed to overload
the westbound Jubilee. I boarded the fourth arriving train at London
Bridge about 0830. ;(

I suppose the day continued in kind.

The failure rate seems much lower than it was about 5 years ago. Double
failures are now rare. 40% delay improvement claims seem pessimistic.

I don't think so. More likely to mean a reported trespasser, I think?

It's happened before on the Central Line.

Peak-time Jubilee line services are packed in Central London even when
nothing goes wrong. They really do need those extra trains, to run a more
frequent service.

I suppose the day continued in kind.

TfL certainly claims that the service is much more reliable these days.

Before or after it failed? (I think things have dropped off trains in
the past).

Yes, driving motors came loose on 92TS a few years ago, and at least one
fell off, derailing the train:

There was also an incident in July 2007 when a train derailed after hitting
some materials that had been badly stowed in a cross passage after weekend
maintenance:

Bits dropping off is a popular failure mode on 92TS isn't it?

Just minor components like drive motors...

It is reported on the District Dave blog that an engineering hours
move of the preserved Cravens unit (back from the EOR) resulted in
damage to the conductor rail. The first service train had several of
its shoes knocked off by the misaligned track. That train was then
stranded. Getting the train out of the way and then repairing the
conductor rail is what took the time. Not the first time this sort of
thing has happened (i.e. damaged conductor rail knocking current shoes
off trains).

Doesn't bode well for future moves for the Cravens unit. I wonder who
will get the bill for that episode?

Thats interesting. Did it get hauled from Ongar all the way by rail? I
thought some track north of Epping had been lifted to seperate the 2
railways. Aside from that I'd imagine it would be in pretty ropey condition
anyway having not been used for 20 years.

Apparently not. The unit was successfully moved to the EOR from
Ruislip depot.

I assume it's had some attention. I wonder if the shoes are still
fitted, as it didn't run under its own power?

From IanVisits:

" Incidentally, as the railway link between Epping and the EOR railway
has been severed, that means three tube trains and two locomotives
will be traveling by road to get to the heritage line. "
