Nineteen people were killed and 40 injured as a double-decker bus toppled in Hong Kong's New Territories area on Saturday, the police told The Sun.
The dead included 15 males and 3 females, police said, revising down their earlier toll of 19 killed at the scene.
Witnesses told horrific stories of watching dazed and bloody passengers drag themselves from the mangled wreckage.
While Hong Kong has a well-developed and generally safe public transportation system, fatal bus crashes have persisted.
Some collapsed by the side of the road in pools of their own blood.
The bus, operated only on race days, was packed with passengers leaving the Sha Tin horse-racing course. The train, which was carrying 78 passengers and five crew, was part of a newly expanded faster rail service along the route linking Seattle and Portland, Oregon - featuring new locomotives.
Mergers: Commission to assess the acquisition of Shazam by Apple
The European Commission has said Apple's takeover of Shazam could have a significant impact on competition in Europe. Apple confirmed plans to buy Shazam late past year in a deal estimated to be worth around $400m (£286m).
'And then it was like the tyre slipped, and the bus turned.
Passengers had complained to the driver who was reportedly 10 minutes late and he then kept speeding up before the bus crashed, the Apple Daily reported, quoting injured passengers at the scene.
"We feel deeply saddened by the accident and offer our condolences to the deceased", government leader Carrie Lam said after paying a visit to the injured at a hospital. It was really chaotic in the bus. "People fell on top of one another and got tossed around from side to side".
Police said the 30-year-old driver was arrested.
The driver of the bus joined the company in 2014.
The injured are being taken to hospitals across Hong Kong and rescuers are still trying to release people trapped inside.
