Screaming and shouting could be heard when Ervin Baraku, 33, was chased into the station during the attack on July 23 last year, the Inner London Crown Court heard.
Evrin was fell down the stairs and he was stabbed in the chest, he then collapsed at the top of the stairs.
He was rushed to hospital, where died a week later on July 30.
Kevin Nguyen, 21, of Westerfield Road in Tottenham, was found guilty at court today (June 12).
The court heard how the chase occurred just before 9am after Nguyen had an altercation with Evrin on the street.
Pedrinho could reportedly be seen with a large knife on CCTV, and was being followed by Nguyen into the station.
Nguyen was arrested the following day on July 24 last year, with Pedrinho arrested a few days later on July 27.
Detective Superintendent Sam Blackburn said: “This was an absolutely senseless and tragic attack that resulted in a man losing his life.
“There is absolutely no place for violence on the railway network, so I am glad to see both Nguyen and Pedrinho will be put behind bars for their part in this brutal murder.
“While no prison sentence can ever make up for the loss of a loved one, I hope justice being served can bring Ervin’s family some peace after this horrific ordeal.”
