'Lots of screeching'

Jane and John, who were on the derailed carriage, told BBC Radio London they thought the train was "going to come off the rails totally".

"There was lots of noise, lots of screeching, lots of sparks, and John and I held on to each other and thought 'we're in trouble if it goes over'," Jane said.

John said: "It felt at one point like it was going to tip, then it didn't, and remarkably, no one was screaming or anything, everyone was pretty calm, but it felt like it came quite close.

"You could tell it was off the tracks."
