RAS question

Consider the following statements regarding India's first hydrogen-powered train: 1. It was developed by the Research Designs and Standards Organisation (RDSO), Lucknow. 2. It successfully completed oscillation trials in March 2026 for the Jind–Sonipat route in Haryana. 3. The trainset has a combined power output of 2,400 kW and produces only water vapour as a by-product. 4. With this development, India will become the third country globally to operate a hydrogen train. Which of the statements given above are CORRECT?

Correct answer: (B) 2 and 3 only.

Only statements 2 and 3 are correct. In March 2026, India's first hydrogen-powered train completed oscillation trials for the Jind-Sonipat route. Its 2,400 kW trainset emits only water vapour.

  1. (A)

    1 and 2 only

  2. (B)

    2 and 3 only

  3. (C)

    1, 3, and 4 only

  4. (D)

    2, 3, and 4 only

Explanation

The developer, testing agency, route and technical features must be distinguished. Integral Coach Factory (ICF), Chennai, developed the hydrogen train. Research Designs and Standards Organisation (RDSO), Lucknow, set the specifications and conducted the oscillation and emergency braking-distance (EBD) tests; it did not develop the train, so statement 1 is incorrect. The oscillation trials for Haryana's Jind-Sonipat route were completed in March 2026, so statement 2 is correct. The 10-coach trainset has two 1,200 kW driving power cars, giving a total capacity of 2,400 kW, and emits only water vapour, so statement 3 is correct. Statement 4 is incorrect because India would become the fifth country, after Germany, Sweden, Japan and China, rather than the third.

Why the other options are wrong

  • (A) Option A includes statement 1, but Integral Coach Factory, Chennai, developed the train; RDSO set the specifications and conducted the tests.
  • (C) Option C includes statements 1 and 4, although RDSO was not the developer and India would become the fifth country to operate a hydrogen train, not the third.
  • (D) Option D correctly includes statements 2 and 3 but also includes statement 4, which incorrectly places India third instead of fifth.

Concept

This question tests science and technology in transport, especially hydrogen fuel-cell mobility and the roles of Indian Railways institutions. RAS often asks such questions because they link current affairs with clean-energy policy, technology, the environment and precise knowledge of public institutions.
