India opens world's highest railway arch bridge built with 28,000 tonnes of steel
The 1,315m bridge, part of the Udhampur-Srinagar-Baramulla Rail Link (USBRL) project, was built with over 28,000 tonnes of Steel, designed to last 120 years, and can withstand high winds (up to 266kmph) and seismic activity (up to magnitude 8).
Engineering challenges included stabilising slopes in the fractured Himalayan geology, with G Madhavi Latha from the Indian Institute of Science advising on slope stabilisation and foundation design, requiring real-time construction plan modifications based on geological data.
Construction involved building 26km of new roads to transport heavy machinery to the remote site, with the USBRL project costing Rs437.8bn (£3.7bn) and the Chenab Bridge alone costing approximately Rs14.86bn (£128m).
The Chenab Bridge, designed with contributions from Indian and international firms, including WSP Finland and Leonhardt Andrä und Partner, aims to significantly reduce travel time between Katra and Srinagar to three hours via the Vande Bharat Express.

York Council moves funds to keep Station Gateway plans on track
More than £18m of funding will be diverted from major projects in York to help pay for work to revamp the front of the city's railway agreed to move money away from the scheme to dual more of York's outer ring road and the former Castle Mills car park redevelopment, in order to complete work at the station, which is already under councillors agreed to "phase" work on the outer ring Lomas, executive member for finance, said: "The station gateway project was at risk, but we have made sure we can deliver all the benefits of the scheme, making sure transport to, from and across the city can work for everyone." Lomas said: "It is not just about trains. This is an integrated transport scheme."We are making the gateway to our city a great place to use, however you use it."The original budget for the project to revamp the front of the railway station was £32.4m, but the council said it had seen cost rises including inflation in building materials and energy completed, the scheme will see the area around the station opened up, with a new square, bus stops and cycle lanes and more space for pedestrians and Kilbane, the Labour-run council's deputy leader, said the station was "the city's shop front – it is hugely important for our city".However, Liberal Democrat group leader Nigel Ayre said: "The York Outer Ring Road is vital for the city."We made the case that phasing the scheme is death by a thousand cuts and should be avoided at all costs."The failure to get on with the ring road scheme has led to huge cost over-runs." The original budget for the Outer Ring Road was £67.4m, but in May the council admitted the costs had risen and there was now a £110m funding shortfall for the authority said inflation, increased utility costs and the need for new bridges and underpasses were among the reasons for the steep budget councillors agreed at a meeting on Tuesday to commit £27m of the existing budget to begin the phased work with the building of a bigger roundabout at Clifton Moor.

Air India to restore some international flights following reduction over crash
BENGALURU, July 15 (Reuters) - Air India said on Tuesday it would partially restore its international flight schedule that was scaled back following the crash involving its flight last month that killed 260 people. As part of the restoration, Air India will start a thrice-weekly service between Ahmedabad and London Heathrow from August 1 to September 30, replacing the currently operating five-times-a-week flights between Ahmedabad and London Gatwick. A Boeing (BA.N), opens new tab 787 Dreamliner bound for London from the Indian city of Ahmedabad began to lose thrust and crashed shortly after takeoff on June 12. All but one of the 242 people on board and 19 others on the ground were killed. Air India reduced some of its international flights following the crash as part of a "safety pause" that the carrier said allowed it to perform additional precautionary checks on its Boeing 787 aircraft. The partial service resumption will see some flights being restored from August 1, with full restoration planned from October 1, 2025, Air India said. As part of the partial resumption, Air India has reduced flights to some destinations in Europe and North America. These include reductions in the frequency of Delhi-to-Paris flights to seven times a week from 12, effective August 1. Flights on the Delhi-Milan route have been reduced to three times a week from four earlier. The frequency of flights from Mumbai and Delhi to New York JFK has been cut to six times a week from seven earlier, the airline said.

The HS2 farrago shows we're a country that can't get its act together
It's not often one wishes for Communism or to live in a full-blown dictatorship, but Derailed: The Story of HS2 (Radio 4, all week) just about had me there. Kate Lamble's terrific 10-part series – available in 15-minute daily bursts if you're squeamish or to be guzzled in one go on BBC Sounds if you're a masochist – portrays a Britain that is neither Orwellian nor Kafkaesque, but a bureaucratic basket-case plucked from the pages of Joseph Heller's Catch-22. It may not fully get to the bottom of why HS2 has been such a monstrous debacle, but it shows how in the most gruesome detail. In Monday's opening episode, Lamble began with perhaps the most damning thing of all. In 2009, the year HS2 first rumbled into life, the West Coast Main Line upgrade had finally finished – years late, billions over budget, with more money spent on compensation than on the actual infrastructure. In other words, the perfect manual for how not to run a railway project. HS2, as we all know too well by now, has made that project look like Swiss clockwork. Lamble spoke to an impressive roster of those involved in HS2, from engineers to MPs, and found a project riven with division from the off, and one so in love with the idea of itself, it was incapable of seeing a yard in front of its face. Some of the details amounted to a national embarrassment: the budget updates tied doggedly to 2012 prices, key figures sacked for providing realistic costings (HS2 Ltd deny this), the wrong trains purchased, trees chopped down on land they didn't own, thousands of properties bought that they still don't know what to do with. One key figure stated that the original budget (around £15bn – current estimates have it going northwards of £80bn) was drawn up when they knew 'three to four per cent of the facts' about the project. The use of guesstimates is stunning. According to the podcast, one necessary piece of land attached to a golf course was valued by HS2 at £3,800. They agreed to buy it for £7m. It's not so much a case of trying to work out who knew what – no one seemed to know anything. In 2014, when the first of the bills passed in parliament, the transport secretary Patrick McLoughlin believed that was tantamount to the planning application being approved. Since then, HS2 has required more than 8,000 further permissions from local councils and other agencies. Yet for all we've completely ballsed it up, Lamble hits upon a key truth. The obsession with the cost and with the speed meant that HS2 had failed to tell the right story. As a result, said Lamble, 'the public got the impression we were about to spend billions just to knock 30 minutes off a trip to Birmingham'. In a country obsessed with the railways, we'd got the narrative wrong, failing to convince the nation that HS2 could be something discussed in 150 years the way we discuss the golden age of Victorian railways now. In 150 years, HS2 will certainly be discussed – as a prime example of the little country that couldn't.
