Named the NaMo Green Rail, this indigenous 10-coach train will run on the Jind-Sonipat route. Powered by a massive 3,200 horsepower system, it ranks among the world’s longest and most powerful hydrogen passenger trainsets! Alongside this launch, the government also unveiled highway and medical projects worth over ₹25,000 crore across northern India.

1. Hydrogen fuel cell trains generate onboard electricity through an electrochemical reaction between stored hydrogen and atmospheric oxygen.
2. The only physical by-product emitted by the propulsion system of a hydrogen fuel cell train is pure water vapour.
3. The ‘Hydrogen for Heritage’ project aims to install high-voltage overhead electrical cables across fragile mountain railway circuits.

Which of the statements given above is/are correct?
(a) 1 and 2 only    (b) 2 and 3 only    (c) 1 and 3 only    (d) 1, 2 and 3

• Statement 1 — Correct: Fuel cells produce clean electricity onboard by reacting stored hydrogen gas with oxygen drawn from the ambient air.
• Statement 2 — Correct: Because it relies on electrochemical conversion rather than fossil fuel combustion, zero greenhouse gases are released; water vapour is the sole exhaust by-product.
• Statement 3 — Incorrect (the trap): The primary objective of the ‘Hydrogen for Heritage’ project is precisely the opposite—it allows clean train operations on heritage mountain routes without needing to build ugly and eco-damaging overhead electrical cables!
