Despacito Luis Fonsi & Daddy Yankee feat. Justin B
Trains in and out of Victoria are back to normal after thousands of people were disrupted getting home on Thursday night.
A man climbed under a train at Thornton Heath just after 5.30pm and refused to move.
He was eventually sedated by paramedics and held under the Mental Health Act- the track didn't reopen until after 8pm.
Some passengers had enough and got off a train and walked down the tracks near Norbury.
Network Rail says it's incredibly dangerous to get off a train and you should stay put.
