In a major safety overhaul, Western Railway will install the indigenously developed anti-collision system Kavach across its Mumbai suburban train network by the end of next year, railway officials have confirmed to news agencyKavach, an Automatic Train Protection (ATP) system developed under the 'Make in India' initiative, is currently being implemented on the Delhi-Mumbai corridor and other key railway routes. It is intended to replace the Auxiliary Warning System (AWS) currently used on the Western Railway's suburban services.Western Railway operates over 1,400 local train services each day on the Churchgate-Virar-Dahanu corridor, with a daily ridership of over 3 million. The current AWS alerts train drivers with audio and visual signals about upcoming signals and assists with speed monitoring and emergency braking. However, officials said the system has limitations in preventing incidents such as Signal Passed at Danger (SPAD) or signal jumping due to its reliance on human intervention."The AWS panel in the motorman's cab has an alarm, a vigilance button, and red, yellow, or blue lights. If the alarm sounds, the motorman must press the button within four seconds, or the brakes will activate and remain locked until the train comes to a complete halt," an official explained.According to railway officials, the AWS's dependence on manual response and limited automation reduces its ability to prevent certain critical safety failures.Kavach, which means 'armour' in Hindi, includes features such as continuous speed monitoring, in-cab signalling, and automatic braking when trains approach a red signal or exceed speed limits.The system ensures real-time communication between trains and signalling infrastructure, allowing automated intervention when safety thresholds are breached."Work has begun on the transition to Kavach. All suburban locals on Western Railway will be equipped with Kavach in addition to mainline locomotives by the end of next year," a senior WR official said.The Western Railway has outlined plans to install Kavach over 2,358 route kilometres. Its commissioning on the Mumbai-Ahmedabad section is expected by the end of the current financial year. Other routes are set to follow."Kavach is poised to improve railway signalling systems and ensure enhanced passenger safety. Deployment of Kavach will also aid efficiency," Western Railway's chief public relations officer Vineet Abhishek said.Kavach is already operational on select sections of the South Central Railway, where it has been deployed over more than 1,400 route kilometres. Indian Railways aims to scale the system across 35,000 route kilometres in phases.The move to install Kavach in Mumbai's suburban system—one of the busiest in the world—is part of a broader effort to modernise safety systems and reduce dependency on manual oversight in train operations.

Data centre industry wary of proposed certification scheme
ETtech The data centre industry has come out against the government's plans to introduce India-specific guidelines for certifying data centres and standardising many of their functions, saying the move is duplicative and unaligned with international draft data centre certification scheme, proposed by the Ministry of Electronics and Information Technology MeitY ), risks creating a major dual compliance burden for operators, hindering both domestic and global market participation, IT and tech industry body Nasscom said in its feedback to the centre operators fear the move doesn't recognise the pace of technological change, or diversity in the by MeitY's Standardisation Testing and Quality Certification (STQC) Directorate, the proposed certification framework seeks to establish standards for data centre operations and maintenance across the STQC – an attached office of the MeitY – already audits government-empanelled Cloud Service Providers (CSPs), Nasscom has questioned the incremental value of the proposed it has suggested a tiered, risk-based assessment that identifies only incremental compliance for those already adhering to global and MeitY standards. 'Additional requirements should be context-specific, and the certification must be explicitly voluntary,' it told the maintains national and international accreditations in the IT field by providing testing, calibration, certification and e-governance services through a nationwide chain of operators already operate with global certifications like Uptime/TIA942, said Sunil Gupta, cofounder, managing director and CEO of Yotta Data Services, a cloud infrastructure and data centre services can be used as baseline by the government for framing additional guidelines for facilities hosting government data, he said.'Additional guidelines for green energy adoption, physical and logical security including telemetry or Internet of Things data for mechanical, electrical, and plumbing equipment can be framed by the government,' Gupta government can also mandate the adoption of Make in India components, availability of sovereign cloud and managed services, and decide whether ultimate ownership of the data centre lies with Indian or foreign citizens or entities, he the policy should have differential expectations from centres with different purposes, he pointed out the draft scheme proposes a uniform approach to all data centres, failing to recognise diverse business models like enterprise, co-location, and large some countries have introduced standards for data centres with a specific local gap in mind, such as Japan's standard for earthquake risk, Nasscom noted jurisdictions rarely introduce exclusive, comprehensive certification schemes beyond existing global industry officials noted a central policy can help streamline data centre policies across states.'In India, every state has a different data centre policy, mandating different building and power regulations, and a lot of time goes in understanding and comparing them,' said Sureshkumar Rathod, president, colocation business, at data centre operator CtrlS.A data centre 'should be built in a year, but in India, it takes a minimum of three and a half to four years,' he said. 'This problem of having to invest without any outcome for a long time is a big one.'Rathod said countries such as Malaysia and Thailand promote data centres as one industry across of July, India has 153 data centres, according to industry sector is poised for explosive growth, with capacity projected to surge 77% by 2027, reaching a staggering 1.8 GW, global real estate services firm JLL said in a report in expansion comes on the heels of the industry surpassing the 1 GW milestone in 2024, growing at a compounded annual rate of 24% since 2019.

Amazon said it will offer the tools on its Bedrock and Sagemaker platforms, adding that their advanced reasoning capabilities make them suited for AI agents OpenAI announced the new 'open weight' models on Tuesday and said they can carry out complex tasks like writing code and looking up information online on a user's perceptions that Amazon is lagging behind its Big Tech peers in artificial intelligence, Chief Executive Officer Andy Jassy has positioned Amazon Web Services as a kind of supermarket that sells a range of AI tools to businesses. The company's Bedrock software platform was designed to make it easier to access other companies' large language models, as well as Amazon's company has partnered with Anthropic, investing $8 billion in the AI startup and using the relationship to bolster its credentials in AI services. AWS offers Anthropic's Claude models to clients on its AI marketplace.
