Speed restrictions imposed on two main train lines amid UK heatwave
Trains have been forced to run slower in southern Britain because of the heatwave, with speed restrictions imposed on two main lines out of London as temperatures on the track neared 60C,Passengers have been urged to check before travelling and warned to expect longer journeys and possible cancellations on routes west from London Paddington and south of the capital on the Brighton mainline,Restrictions were put in place at the weekend for the Brighton mainline through Monday and Tuesday, affecting Southern, Thameslink and Gatwick Express services,Network Rail and train operators decided at midday on Monday to extend the speed restrictions to the western mainline, affecting primarily Great Western trains running to the south-west and south Wales,As temperatures in the south exceeded 30C, steel rails were heating up to about 60C in the hottest parts of the tracks such as deep cuttings and suntraps, according to Network Rail.
Other factors such as timber rather than concrete sleepers, and the speed of trains, increase the risk of buckling or failure.The speed restrictions imposed west of Paddington through the Thames valley area were likely to mean a 10- to 15-minute delay on most trains, according to a GWR spokesperson.The compounding delays were expected to bring more disruption and cancellations later in the day.Glastonbury returnees mostly avoided further duress: GWR said it had already picked up more than 6,000 festivalgoers from Castle Cary station in Somerset on Monday morning before the speed restrictions started.With temperatures expected to nudge higher, railway managers confirmed the speed restrictions would stay in place until 10pm on Tuesday night.
The heat has not reached the extremes of three years ago, when services across England and Wales were disrupted and under speed restrictions amid fears that rails would buckle,Network Rail painted critical sections of the railway white this spring to help reduce the impact of heat,The state-owned company is wrestling with the impact of the climate crisis on more than 20,000 miles of track, thousands of signals, stations and level crossings that it owns and maintains,A spokesperson for Network Rail and the train operators said: “With temperatures set to soar as forecast by the Met Office, speed restrictions have to be imposed across large parts of the network to ensure everyone’s safety,Sign up to Headlines UKGet the day’s headlines and highlights emailed direct to you every morningafter newsletter promotion“We’re sorry but this means we won’t be able to run as many trains as normal and journeys will take longer.
Trains that are running will also be much busier,If you are able to work from home, then that may be your best option,“If you do take the train, then please remember to take a bottle of water, and if you begin to feel unwell, seek help at the next station and speak to station staff,Pulling emergency alarms onboard may delay us getting help to you,”While passengers in northern England and Scotland have escaped the heat, those hoping to take the west coast mainline north of Carlisle to and from Glasgow were left unable to travel after a tree fell and blocked the line.

Jeff in Venice: seven takeaways from the Bezos-Sánchez wedding
Amazon founder Jeff Bezos and journalist Lauren Sánchez held their wedding ceremony in Venice’s Grand canal on Friday, the centrepiece of a three-day gala that drew dozens of stars but also protests by local activists. Here are seven takeaways.The couple kicked off celebrations with a foam party on their $500m (£364m) super yacht moored near the Croatian island of Unije. Coinciding with Sánchez’s son Evan Whitesell’s 19th birthday, paparazzi photos showed the couple wearing swimwear and sunhats covered in frothy suds as they partied alongside Whitesell and his friends. Foam parties can cause conjunctivitis, so the decision to hold one just days before their nuptials was somewhat surprising but maybe billionaire foam hits different

The Black Death. Byron on the prowl. Rising water levels. Cruise ships the size of city blocks.

Google’s emissions up 51% as AI electricity demand derails efforts to go green
Google’s carbon emissions have soared by 51% since 2019 as artificial intelligence hampers the tech company’s efforts to go green.While the corporation has invested in renewable energy and carbon removal technology, it has failed to curb its scope 3 emissions, which are those further down the supply chain, and are in large part influenced by a growth in datacentre capacity required to power artificial intelligence.The company reported a 27% increase in year-on-year electricity consumption as it struggles to decarbonise as quickly as its energy needs increase.Datacentres play a crucial role in training and operating the models that underpin AI models such as Google’s Gemini and OpenAI’s GPT-4, which powers the ChatGPT chatbot. The International Energy Agency estimates that datacentres’ total electricity consumption could double from 2022 levels to 1,000TWh (terawatt hours) in 2026, approximately Japan’s level of electricity demand
Ex-Doge employee ‘Big Balls’ gets new Trump administration position
Edward Coristine – the 19-year-old who quit Elon Musk’s controversial so-called “department of government efficiency” (Doge) earlier this week, where he gained notoriety in part for having used the online moniker “Big Balls” – has in fact been given a new government job, this time at the Social Security Administration (SSA).Coristine, whose lack of experience and super-loyalty to Musk saw him become a flashpoint for outrage at Doge’s ruthless but haphazard efforts to slash government spending and fire thousands of workers, resigned from Doge earlier this week.However a spokesperson for the SSA, Stephen McGraw, told Wired magazine that Coristine was now working for that department.“His work will be focused on improving the functionality of the Social Security website and advancing our mission of delivering more efficient service to the American people,” McGraw told Wired.Coristine may have previously worked for the SSA, but reporting on his employment history is conflicted
