India’s First Hydrogen Train: How Indian Railways Is Engineering the Future of Zero-Emission Rail Transport

The pilot train has been developed for the Jind-Sonipat section of Northern Railway in Haryana, where dedicated hydrogen production, storage and refuelling infrastructure has also been established. Unlike a conventional diesel train, the new trainset will generate electricity onboard using hydrogen fuel cells, producing only water vapour and heat as by-products, thereby eliminating tailpipe carbon emissions.

Unravelling the Secrets of Near-earth Space Critical for Satellite Operations

Understanding how the electron density varies with height in the ionosphere is therefore essential for reliable communication and navigation, especially in the equatorial regions where ionospheric dynamics are highly complex. Accurate electron density information up to ~1000 km is essential for continuous monitoring of the ionosphere, as most low Earth orbit (LEO) satellites operate within this altitude range.

India’s Smartphone Manufacturing Push Gets Fresh Momentum After Tariff Cuts On Key Components

The tariff relief covers components that are important for high-value electronics manufacturing, including wireless charging modules for smartphones, lithium-ion cells and display-related components used in sectors such as medical devices and automobiles. Duties of 5% and 7.5% on several such items have been removed, giving manufacturers a clearer cost advantage as they scale local assembly and component integration.

India and New Zealand: Cultural Echoes Between Bharat and Aotearoa

In the 19th and early 20th centuries, some writers tried to connect Māori origins directly with India, Sanskrit and so-called Aryan ancestry. Te Ara records that Edward Tregear argued in the 1880s that Māori language, mythology and customs contained signs of Aryan-Indian heritage, and Te Ara also notes that older theories placed Māori origins in many places, including India, Greece, Egypt, Palestine and the Americas.

The ministers also exchanged views on developments in the Gulf and explored ways to support peace and regional stability.

India’s Largest Rail TBM Begins Tunnelling for Mumbai–Ahmedabad Bullet Train

The Mixshield TBM is among the largest rail-tunnelling machines deployed in India. It has a 13.6-metre-diameter cutterhead, weighs approximately 3,100 tonnes and stretches around 96 metres. The machine will construct nearly six kilometres of single-tube tunnel, wide enough to accommodate both the upward and downward bullet-train tracks. Its route passes beneath densely built parts of Mumbai, major roads, existing infrastructure and the Mithi River.

ISRO Clears CE20 Cryogenic Engine for Next LVM3 Mission

The CE20 engine powers the cryogenic upper stage of the LVM3 launch vehicle, India’s heaviest operational rocket. LVM3 is the vehicle that carried landmark missions such as Chandrayaan-2 and Chandrayaan-3, and it has also supported commercial satellite launches. The engine has now successfully flown on eight consecutive LVM3 missions, giving it a strong operational record in India’s launch vehicle fleet.
