Q: Which technology is being used by Indian Railways to monitor the health of tracks and prevent accidents without manual patrolling?
Answer: Drones
Explanation: Drones are used for aerial inspection of bridges, tracks, and ongoing project sites. This technology reduces the need for human intervention in difficult terrains and improves efficiency. It also helps in identifying encroachments and monitoring vegetation growth along tracks.
Q: What is the benefit of using 'Aluminum' coaches instead of stainless steel in terms of sustainability?
Answer: They are lighter and more energy-efficient
Explanation: Aluminum coaches are significantly lighter than steel ones, which means the locomotive requires less energy to pull the train. This leads to higher speeds and lower fuel or electricity consumption. Furthermore, aluminum is highly recyclable at the end of its lifespan.
Q: Indian Railways uses 'Plastic Bottle Crushing Machines' at stations to promote?
Answer: Recycling of PET bottles
Explanation: These machines encourage passengers to dispose of their empty bottles responsibly rather than littering. The crushed plastic is then sent for recycling into products like clothing and bags. Many stations offer small mobile recharge incentives for using these machines.
Q: The 'Green Ribbon' on the Indian Railways logo for certain projects signifies?
Answer: Environment-friendly projects
Explanation: The green marking is used to distinguish initiatives that contribute to ecological sustainability. It helps in branding the railways as a modern, responsible transport mode. This is part of the larger 'Mission 41K' to save energy costs.
Q: Which station was the first in India to receive a Gold rating from the IGBC?
Answer: Vijayawada
Explanation: Vijayawada Junction was a pioneer in adopting green building standards and received the Gold rating early on. It implemented energy-efficient designs and massive tree plantation drives. The station has since moved towards even higher environmental certifications.
Q: What is 'Bio-Vacuum' toilet technology, a more advanced version being tested in premium trains?
Answer: Use of suction with bio-digesters
Explanation: Bio-vacuum toilets use a small amount of water and high-pressure suction to move waste to a bio-digester tank. This technology is similar to those used in airplanes and reduces water consumption by over 70%. It also effectively eliminates foul odors in the coach.
Q: The term 'Traction Power' in Railways refers to electricity used for?
Answer: Moving the trains
Explanation: Traction power is the energy consumed by locomotives to pull the train loads. Indian Railways is one of the largest consumers of electricity in India for this purpose. Transitioning traction power to solar and wind is the biggest step toward Net Zero.
Q: Which of the following is a 'Green' initiative for station cleaning?
Answer: Mechanized cleaning
Explanation: Mechanized cleaning uses high-pressure jets and machines that use less water and provide better hygiene. It reduces the physical burden on sanitation workers and ensures a chemical-free clean. This is standard at all 'A1' and 'A' category stations.
Q: Indian Railways is installing 'Natural Day-lighting' pipes at workshops to?
Answer: Reduce daytime electricity use
Explanation: These pipes reflect natural sunlight into large indoor spaces like workshops and station halls. This eliminates the need for electric lights during the day, resulting in zero-cost lighting. It is a cost-effective way to improve the working environment and save energy.
Q: What is the primary benefit of 'Vertical Gardens' being installed at station pillars?
Answer: Aesthetics and air purification
Explanation: Vertical gardens improve the visual appeal of concrete structures while absorbing carbon dioxide and dust. They help in reducing the local temperature around the station area. This initiative is common in major metropolitan stations like Bengaluru and Mumbai.
