Indian Railways · हरित रेलवे · Questions 1–10 of 50
Indian Railways has set a goal to become a 'Net Zero Carbon Emitter' by which year?
Correct Answer: A. 2030
The goal is to eliminate carbon emissions by transitioning completely to renewable energy sources by 2030. This strategy includes 100% electrification of all broad gauge tracks. It is one of the largest green initiatives by any railway network globally.
Which type of toilets are being installed in Indian Railways to prevent the corrosion of tracks and maintain hygiene?
Correct Answer: C. Bio-Toilets
Bio-toilets use anaerobic bacteria to decompose human waste into water and gases. This technology prevents direct discharge onto the tracks, thereby protecting the steel rails from corrosion. By 2020, Indian Railways successfully fitted 100% of its passenger coaches with these units.
Which Indian railway station became the first to be fully powered by solar energy?
Correct Answer: D. Guwahati
Guwahati railway station in Assam achieved this milestone by installing a high-capacity solar power plant on its roof. The project helps in reducing high electricity costs and promotes sustainable infrastructure. It serves as a model for green energy adoption in the Northeast region.
The 'Green Rating' for railway stations in India is provided by which organization?
Correct Answer: A. Indian Green Building Council (IGBC)
The IGBC evaluates stations based on parameters like energy efficiency, water conservation, and waste management. Stations can receive ratings such as Silver, Gold, or Platinum. This system encourages railway authorities to adopt eco-friendly building practices.
What is the primary purpose of the 'Head-on-Generation' (HOG) technology in trains?
Correct Answer: C. To eliminate the need for power cars
HOG technology draws power for lights and fans directly from the overhead electric wires instead of using diesel generators. This significantly reduces noise pollution and saves millions of liters of diesel every year. Most Rajdhani and Shatabdi trains have now transitioned to this efficient system.
Which railway zone in India became the first to achieve 100% electrification of its broad gauge network?
Correct Answer: D. West Central Railway
West Central Railway, headquartered in Jabalpur, completed the total electrification of its tracks in March 2021. Electrification is a key pillar for achieving the Net Zero Carbon goal. It reduces dependency on imported fossil fuels and lowers operational costs.
What is the name of the vertical solar plant technology being tested for boundary walls of railway tracks?
Correct Answer: A. Bifacial Solar Panels
Bifacial solar panels can capture sunlight from both the front and the back sides. These are being explored for track boundaries to maximize energy generation in limited spaces. This innovative use of land helps in generating green power without additional land acquisition.
Indian Railways is planning to run trains powered by which clean fuel to reduce the carbon footprint on non-electrified routes?
Correct Answer: C. Hydrogen Fuel Cells
Hydrogen-powered trains, often called 'Hydrogen for Heritage,' are being developed for scenic and narrow-gauge routes. These trains emit only water vapor and are much quieter than conventional diesel engines. This technology represents the cutting edge of sustainable rail transport.
Which rating level is the highest under the IGBC Green Railway Stations rating system?
Correct Answer: D. Platinum
The Platinum rating is awarded to stations that exhibit superlative performance in environmental sustainability. Parametres include green cover, use of LED lights, and rainwater harvesting. Secunderabad was among the first major stations to receive this top-tier certification.
To conserve water, Indian Railways has set up 'Automatic Coach Washing Plants' (ACWP) which use?
Correct Answer: D. Recycled water
ACWPs are designed to wash a full train rake in minutes while using significantly less fresh water. These plants feature water treatment systems that allow for the recycling of up to 80% of the water used. This initiative helps in substantial water conservation at major maintenance depots.
