Eileen Harris, 60 was on the train to travel to Tunbridge Wells in Kent when the fire started.
She described the chaos when the fire broke out and how some of those on board initially feared it was a bomb.
Suddenly the doors burst open and a woman ran through shouting there's a bomb on the train, everybody get off. We ran away towards the opposite end of the station because I thought that if there was a bomb, they'd probably take out the concourse. But the staff kept saying to us come back in and we really didn't want to come back through the station, because by then there was thick smoke.
Where the fire was there were big bangs and pops and flashes. And the smoke, the smoke was the worst thing.
Mrs Harris' 26-year-old son Daniel was travelling with her on the train:
There was fire and lots of thick smoke, so we assumed that there was a bomb ripping through the train. People were running through the train, and my first thought was the reason they're running down the train is because they can't get off. No-one really knew what was going on.
A passenger who was on the Southeastern train which caught fire at Charing Cross this morning has spoken of his ordeal.
Vincenzo Minore, who is from west London and the CEO for cosmetics company Soap and Glory, was on board with his wife, two children and in-laws, when the fire broke out.
I was sitting on the train with my family when there was a blast and a lot of light. You could see the fire - it was not like a normal fire, it was pushing out and consistently burning.
We walked away from the fire but it was in the wrong direction. The security services arrived quickly and escorted us out. We had to walk right past the fire which was quite worrying.

A murder investigation has been launched following the discovery of a body in a New Barnet flat after a fire on Thursday.
Firefighters who tackled the blaze at Sheridan Lodge on Potters Road called police when they discovered the body of 49-year-old Antonio James Tammaso, who lived alone in the flat. They also found a petrol can in one of the rooms.
