The men kept fighting as horrified train members of the public watched on.
Officers from the British Transport Police attended the scene with paramedics where one woman was treated for a head injury.
It happened at Abbey Wood railway station, near Greenwich, southeast London.
The incident occurred on platforms three and four on the newly opened Elizabeth Line.
It happened on Saturday (20 Apr) evening, with police being called to attend the scene at 23:59pm.
A platform official made attempts to calm the situation down but was hopelessly outnumbered.
One shocked rail passenger retreated to the steps and watched on in horror.
They then filmed the melee in a 49-second video on their mobile phone.
Claudia Ciobanu suggested: “At this point having a citizen crime app is a must.”
Ian Hughes stated: “London, Khan, what do you expect.”

A third said: “Scary. I’m hoping no one was badly hurt.”
Jemmy added: “Wild animals shouldn’t be allowed in public.”
