A tense video has captured a man exploding into an expletive-ridden rant and threatening to "smash" a female passenger on a packed train during peak hour.

Footage of the chilling confrontation on a Sydney train was shared on Reddit.

While much of what the man said was incoherent, some viewers were able to translate parts of his rant from Arabic.

The video begins with the man swearing and pointing at two female passengers, prompting a brave commuter to step in and tell him: "don't talk to her like that".

He responded by saying, "I swear I'll smash you", which sparked a swift response from several men urging him to calm down.

One male passenger then told the women to switch seats so he could sit behind the angry man and they could be further away.

"Get f***ed or I'll smack your f***ing neck," the heated man told one of the women as she walked away from the scene.

The man who took a seat behind him calmly responded saying, "No you're not, you're not going to smack anyone."

The heated situation continued when the man began shouting "police" across the carriage.

"F**k Islam. F**k your god. F**k your mosque. Get off my d**k. I'll shoot you in the head. I'll also shoot you in the head," the man said, according to one viewer's translation.

"He is speaking Arabic with a Lebanese accent. He's not very coherent but appears he has something against Muslims. Obviously, he's Christian, as he uses the word Rab which means God," one person claimed in a comment.

Passengers remained calm throughout the alarming ordeal – a detail viewers of the video found particularly admirable.

"I applaud all those around him who showed patience and restraint," the translator wrote.

"Good on old mate for stepping in and keeping the spinner in check. I hope he was taken care of later," someone else said.

"Yeah the black cap guy was awesome. Made everyone feel safe while de-escalating," another wrote.

Sydney Trains was unable to comment on the incident given it was unclear where and when it unfolded.
