An eyewitness who was on the train at the time of the incident says passengers were left in "pure panic" as bleeding victims called out for help.
Olly Foster told the BBC he initially heard people shouting "run, run, there's a guy literally stabbing everyone", and believed it might have been a night-after-Halloween prank.
Within minutes, people started pushing through the carriage, and Foster noticed his hand was "covered in blood" as there was "blood all over the chair" he had leaned on.
An older man "blocked" the attacker from stabbing a younger girl, leaving him with a gash on his head and neck, Foster said. Passengers around him used jackets to try to staunch the bleeding.
He added that the only thing people in his carriage could use against the attacker was a bottle of Jack Daniel's whiskey, leaving them "praying" that he would not enter the carriage.
Although it lasted 10 to 15 minutes in total, Foster says the incident "felt like forever".

British Transport Police have confirmed to the BBC that those responding to a mass stabbing on a train near Huntingdon at one point declared "Plato", which is the national code word used by police and emergency services when responding to a "marauding terror attack".
This declaration was later rescinded, police said.
We reported earlier that police have now declared a "major incident", and the investigation is being supported by counter-terrorism officers.
For those who are just joining us, it's been almost six hours since police first received reports of multiple stabbings aboard the 18:25 service from Doncaster to King's Cross.
After receiving that call at 19:42, a large number of emergency responders attended the scene at Huntingdon Station in Cambridgeshire, where the train made an unscheduled stop.
Police have since confirmed that nine people are in hospital with life-threatening injuries. A tenth person is being treated in hospital with non life-threatening injuries.
Two people have been arrested in connection with the incident, and are currently in police custody.
The investigation is being supported by counter-terrorism officers, and police say that trains are still not running in the area. There are also a number of road closures that remain in place.

In an update from British Transport Police, Chief Superintendent Chris Casey called the stabbing attack a "shocking incident", but said he was unable to speculate on the cause.
"Our response is ongoing at the station and will be for some time," he said, adding that trains were not currently running in the area and road closures would continue.
As we reported earlier, ten people have been taken to hospital, with nine of those patients suffering "life-threatening injuries".
Police said that they have declared a "major incident" and the investigation is being supported by counter-terrorism officers as they work to establish a motive.
"It could take some time before we are in a position to confirm anything further," the chief superintendent said, before thanking the public for their "patience and co-operation".

I've been speaking to a man who was standing on a platform at Huntingdon station as the train approached at around 20:00.
London Underground worker Dean McFarlane tells me he saw the train pull in with a passenger onboard bleeding.
McFarlane says that on arrival, he saw multiple people start running down the platform bleeding, with one man in a white shirt "completely covered in blood".
He says he grabbed people and told them to leave the station, and tried to assist passengers who were having panic attacks.
We are now getting more pictures from the scene in Huntingdon, Cambridgeshire, where a significant emergency response is still underway.
We still don't know how many people have been injured in the incident, but police confirmed that "a number of people" have been taken to hospital.
We can bring you some eyewitness testimony from a person who was on the train that stopped in Huntingdon following the stabbing incident.
Wren Chambers first became aware that something was amiss when a man bolted down the carriage with a bloody arm, saying "they've got a knife, run".
Wren and their friend ran to the front of the train and saw a man who had collapsed on the floor. Wren said they felt "stressed and pretty scared" once they knew what was happening.
They were able to get off the train unharmed.
