Question 1

Indian Railways has set a goal to become a 'Net Zero Carbon Emitter' by which year?

Accepted Answer

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.

Question 2

Which type of toilets are being installed in Indian Railways to prevent the corrosion of tracks and maintain hygiene?

Accepted Answer

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.

Question 3

Which Indian railway station became the first to be fully powered by solar energy?

Accepted Answer

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.

Question 4

The 'Green Rating' for railway stations in India is provided by which organization?

Accepted Answer

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.

Question 5

What is the primary purpose of the 'Head-on-Generation' (HOG) technology in trains?

Accepted Answer

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.
