How did that happen? The alarms haven't been linked to the brakes
since the trains were refurbished AFAIK.

B2003

One train at Wood Green had smoke pouring out from under the car. This
turned out to be papers that had probably burnt from being wrapped
round traction current shoes and arcing.

In the opposite direction there was a passenger alarm on a train.

Also, just before this, there was a signal track circuit failure at
Turnham Green Eastbound, it turned out to be a metal bar, so some
services were held up in congestion as they applied their rule and
others ran down the local line.

As usual, keeping as many trains in service as possible (though at
least some were cancelled) meant that there were then train operator
relief issues and late running of up to an hour.
