A faulty northern line train caused passengers to flee from Angel station.

Just as the southbound train approached the Angel platform at about 8.30pm on Saturday, it stopped for 10 minutes before smoke began to emerge and passengers ran for the exit.

But a Transport for London (TfL) spokeswoman said the smoke, from the back of the train, was caused by brakes hanging out of place, causing friction.

Sonia Mazzotta was on the service as she travelled to Clapham for a night out.

She said: “I was travelling on the northern line southbound when the train was approaching Angel station and stopped. You could tell something was wrong as the train wasn’t all the way along the platform.

“We were sitting there for 10 minutes. They said they were investigating an issue and opened a few doors. I then saw people running towards the exit as smoke was coming from the back of the train.

“It was quite dusty and they told us to leave the station. But I was quite calm because in those situations you have to be calm. You can’t allow panic to overwhelm you.”

Southbound services between Camden and Kennington were cancelled as operators dealt with the problem, before resuming at 9.15pm. The TfL spokeswoman apologised for any journey delays.
