A woman who was hit by a train at Angel Underground station on Monday is reported to have “life-changing injuries”.

British Transport Police (BTP) were called to the southbound platform of the Tube station in Upper Street at about 7.20am, where they found the woman injured. She has been taken to hospital.

The incident isn’t being treated as suspicious. Police were this week trying to trace her next of kin.

A witness to the aftermath of the incident, Michael Brennan, described how the train was held at the platform and then he heard another passenger scream.

Michael then claims he bent down to look at the track below, thinking someone might have dropped their keys. But instead he saw a shoe, and then he spotted the stricken woman.

“I’m surprised there was no staff there at that time in the morning,” he said. “We can’t be relying on members of the public to be looking under trains for people.”

He added: “I was trying to communicate with the woman and console her while another man called an ambulance. There was still no TfL staff on the platform. It was totally chaotic.”

But Marcia Williams, head of customer service for the Northern line, said the station was staffed – although it is understood workers may have been in the ticket hall or office at the time.

“The safety of our staff and customers is always our first priority,” she said. “The station was staffed at the time of this incident, and our staff were in constant communication with our control centre in order to make sure that we responded as quickly and effectively as possible.”
