A driverless train ran for almost four miles on the London Underground
on Friday morning.

The engineering train on the Northern line was allowed to roll between
Archway and Warren Street stations, TfL has confirmed.

The incident, which happened at 0640 BST, is now being investigated by
London Underground.

Transport for London (TfL) said the train moved at slow speed with no
risk to the safety of passengers or staff.

A TfL spokesperson said: "A full investigation has been launched into
this incident."

So this is why the Northern Line was, and is still suspended. *It was
described as "late finish to overnight engineering work"

Sounds like a serious screw up, thankfully no-one got hurt. RAIB will
of course be involved.

The fact it happened at 0640 suggests that there were already serious
problems with engineering work overrunning - the first southbound
train from Highgate is (or should be) at 0536 - a whole hour earlier -
whilst the first northbound train is at 0602. That is, of course, if
the report of the incident happening at 0640 is reliable. Also, I
suppose it's possible that the works train could have been running
amongst normal traffic.

The current situation is interesting - two sections of the line are
closed, but a section through which the runaway train ran is open.

Current situation (from TfL website live travel news) as at 11:55:

* Northern line
Suspended between Finchley Central and Archway and between Camden Town
and Kennington via Charing Cross and minor delays on the rest of the
line due to the late finish to engineering at Highgate.

Tickets will be accepted on local buses and First Capital Connect
trains.

I guess the investigators are looking at the location where it rolled
away - so one of the platforms at Archway or maybe somewhere north
thereof, but the other platform is being used to reverse the trains
that are running to and from points south - and also, presumably, the
investigators are also looking at where the train came to a halt at
Warren Street, and the train is quite possibly still there I suppose,
anyhow this then blocks off using the CX branch.- Hide quoted text -

I was saying on UK Railway that everything was running via Bank to
Edgware, with overrunning engineering work mentioned in announcements.

Nothing was running to Archway, certainly not at 0820 or so, and
punters were advised that it was not known when anything would, and to
get a bus from Camden Town. This was in contradiction to recorded
announcements about being suspended between Finchley and Archway.

The sections closed were presumably where the work overran and where
the train ended up. I did assume that maybe the works overran because
the train had run away, but maybe there were other problems. This
extra information about the timings (if correct) would suggest that
there were.
