Green Railways — Set 5

Correct Answer: B. Longer life and lower energy use

LEDs are essential for the green mission as they consume nearly 50% less power than traditional bulbs. They also last much longer, reducing the amount of electronic waste produced. Indian Railways has completed 100% LED replacement at all its stations.

Correct Answer: B. Reducing food waste and local sourcing

E-catering allows passengers to order exactly what they need from local vendors, reducing bulk food waste in pantry cars. It encourages the use of local, fresh ingredients and reduces the energy used in large-scale on-board cooking. It also offers more choices for sustainable packaging.

Correct Answer: A. Northeast Frontier Railway

The Darjeeling Himalayan Railway, part of the Northeast Frontier zone, uses iconic steam and diesel engines. While steam is traditional, newer eco-friendly measures are being taken to preserve these heritage routes. These small trains are a major draw for sustainable tourism.

Correct Answer: B. Total greenhouse gases produced

The correct answer is 'Total greenhouse gases produced'. In the context of Green Railways, reducing the carbon footprint means lowering the CO2 emissions from operations. By moving from diesel to electric and solar, the railways significantly lower this impact. It is the primary metric for measuring the success of the 2030 goal.

Correct Answer: B. Piezoelectric tiles

Piezoelectric technology generates a small electric charge when pressure is applied, such as people walking. These tiles are being tested in high-footfall areas of major stations like New Delhi. It is an innovative way to harvest 'human energy' for station use.

Correct Answer: B. Digitalizing complaints and reducing paper

Rail Madad is a digital platform that integrates all grievances and suggestions, eliminating the need for physical forms. This move toward 'paperless' administration saves thousands of trees annually. It also provides real-time feedback for maintaining cleanliness and green standards.

Correct Answer: A. Rainwater Harvesting

Rainwater Harvesting is a mandatory feature for all new railway infrastructure to ensure sustainability. It captures rain from roofs to recharge dry wells and underground aquifers. This reduces the railway's dependence on municipal water supplies.

Correct Answer: B. The process of pulling trains

The correct answer is 'The process of pulling trains'. Traction energy is the power used by locomotives to move. Switching from diesel traction to electric traction is the single biggest contributor to lowering railway emissions. This transition is the core of the 2030 Net Zero target.

Correct Answer: C. National Railways Award

The National Railways Awards recognize employees who contribute significantly to efficiency and sustainability. This includes innovations in energy saving, waste management, and solar adoption. It motivates the workforce to participate in the 'Green Railways' mission.

Correct Answer: B. Science Express

Science Express is a mobile exhibition train that travels across India to spread awareness about climate change and biodiversity. It is a collaborative initiative of the Ministry of Railways and the Department of Science and Technology. It has completed many successful phases, reaching millions of students.
