An investigation has been launched after a rail passenger was forced to run several metres along the platform with his hand trapped inside the doors of a moving train in west London.

The passenger, who was trying to board an Elizabeth line service just after midnight, had his hand caught in the door as it began to depart, the Rail Accident Investigation Branch (RAIB) said on 24 December, The Guardian reported.

He was then forced to run alongside the moving train for several metres until a member of railway staff who was working on the platform at Ealing Broadway station pulled him away.

Nearby passengers alerted the driver and the train stopped after moving about 17 metres. The passenger is reported to have sustained minor injuries, the RAIB confirmed.

The “trap and drag” incident, which took place on 24 November at about 12.07am, is the latest case of a rail passenger having to run alongside trains with their hand or arm trapped in doors at stations. Previous incidents took place at Enfield Town, north London, in July; Seven Sisters, north London, in June 2022; Bushey, Hertfordshire, in March 2018; and Newcastle Central in 2013.

The RAIB investigation will consider factors such as if anything influenced the actions of those involved, and how risks associated with passengers boarding and alighting Elizabeth line trains are managed. It will publish its findings, including any recommendations to improve safety.

Elizabeth line services are operated by MTR Elizabeth line under a concession from Transport for London.

A TfL spokesperson said: “We’re sorry that our customer experienced this distressing incident. Safety is our top priority and our operator, MTR Elizabeth line, is currently carrying out a thorough investigation.

“We will always strive to learn from incidents and improve operational safety. MTR Elizabeth line is fully co-operating with the RAIB to establish the root cause of this incident to determine what steps they can take to avoid any further events of this nature and to share learnings with the industry.

“While serious injuries on our network are rare, we are undertaking a huge range of work aimed at eradicating such incidents and making travelling even safer for everyone.”



These Canadian Rocks May Be the Oldest on Earth

Scientists have identified what could be the oldest rocks on Earth from a rock formation in Canada.

The Nuvvuagittuq Greenstone Belt has long been known for its ancient rocks — plains of streaked gray stone on the eastern shore of Hudson Bay in Quebec. But researchers disagree on exactly how old they are.

Work from two decades ago suggested the rocks could be 4.3 billion years old, placing them in the earliest period of Earth's history. But other scientists using a different dating method contested the finding, arguing that long-ago contaminants were skewing the rocks' age and that they were actually slightly younger at 3.8 billion years old.

In the new study, researchers sampled a different section of rock from the belt and estimated its age using the previous two dating techniques — measuring how one radioactive element decays into another over time. The result: The rocks were about 4.16 billion years old.

The different methods "gave exactly the same age,” said study author Jonathan O'Neil with the University of Ottawa.

The new research was published Thursday in the journal Science.

Earth formed about 4.5 billion years ago from a collapsing cloud of dust and gas soon after the solar system existed. Primordial rocks often get melted and recycled by Earth's moving tectonic plates, making them extremely rare on the surface today. Scientists have uncovered 4 billion-year-old rocks from another formation in Canada called the Acasta Gneiss Complex, but the Nuvvuagittuq rocks could be even older.

Studying rocks from Earth's earliest history could give a glimpse into how the planet may have looked — how its roiling magma oceans gave way to tectonic plates — and even how life got started.

“To have a sample of what was going on on Earth way back then is really valuable,” said Mark Reagan with the University of Iowa, who studies volcanic rocks and lava and was not involved with the new study.

The rock formation is on tribal Inukjuak lands and the local Inuit community has temporarily restricted scientists from taking samples from the site due to damage from previous visits.

After some geologists visited the site, large chunks of rock were missing and the community noticed pieces for sale online, said Tommy Palliser, who manages the land with the Pituvik Landholding Corp. The Inuit community wants to work with scientists to set up a provincial park that would protect the land while allowing researchers to study it.

“There's a lot of interest for these rocks, which we understand,” said Palliser, a member of the community. “We just don't want any more damage.”
