Police are investigating the death of a 16-year-old girl after she became trapped under a light rail tram in Sydney's CBD.
Emergency services were called to George Street in Haymarket at midnight on Thursday to investigate reports a pedestrian, identified as Kyra Dulguime, had been trapped under the vehicle.
Police from Sydney City Police Area Command found Ms Dulguime with critical injuries.
Emergency services, including police rescue and Fire and Rescue NSW officers, worked for some time to free the teenager from Sydney's south.
Ms Dulguime was treated at the scene by NSW Paramedics but could not be revived.
Police told the ABC the girl was trying to climb over the gap in between the tram carriages when it ran her over.
A 52-year-old man driving the tram was taken to hospital for mandatory testing.
Security guard Andre Nakad saw the tragedy unfold and called triple-0.
"I can see people yelling and screaming … I think maybe it's a fight," Mr Nakad said.
"I jumped into see if I can help and I see a young Caucasian female screaming and crying, and when I look I see one person stuck under the light rail.
"It's very sad day, very bad situation, it's not easy."
A number of people gathered at the site of the incident this evening for a candlelight vigil.
Transport for NSW secretary Howard Collins issued a statement earlier on Thursday extending the agency's condolences to Ms Dulguime's family.
"Everyone at Transport for NSW is saddened by the death of a teenage girl at a light rail stop in central Sydney overnight," he said.
"We extend our deepest condolences to her family, friends and loved ones.
"We thank emergency services, staff and anyone who rendered assistance for their efforts last night and we will provide our staff with the support they need."
Fire and Rescue NSW spokesman Adam Dewberry said a critical incident briefing had begun and firefighters who attended were being offered psychological support.
"We've also initiated some contact with our wellbeing team and they're the people that start the process to make sure we have the right mechanisms to look after the psychological wellbeing of our firefighters," he said.
A crime scene has been established and a report will be prepared for the coroner.
Light rail services were suspended between Central Station and Circular Quay but have now resumed.
