Indian Railways · हरित रेलवे · Questions 11–20 of 50
The 'Waste to Energy' plant, which converts non-recyclable waste into electricity for the railways, is located in?
Correct Answer: A. Bhubaneswar
The plant at Bhubaneswar uses Polycrack technology to convert plastic and E-waste into light diesel oil and gas. This gas is then used to generate electricity for the carriage repair workshop. It is the first of its kind in the Indian Railways network.
Which feature is being added to newly manufactured railway coaches to reduce energy consumption for lighting?
Correct Answer: C. LED lights
Indian Railways has replaced traditional lighting with energy-efficient LED lights in all stations and coaches. LEDs consume less power and have a much longer lifespan than conventional bulbs. This simple change has led to significant savings in the annual energy bill.
What does the term 'Regenerative Braking' refer to in electric locomotives?
Correct Answer: D. Energy recovery during braking
When an electric train applies brakes, the motors act as generators and pump electricity back into the overhead wires. This recovered energy can then be used by other trains on the same line. It improves the overall energy efficiency of the railway system by nearly 15-20%.
Which state's railway network became the first to be 100% electrified in India?
Correct Answer: A. Haryana
Haryana achieved 100% electrification of its railway lines in early 2023. This milestone supports the national objective of moving towards a greener and faster rail network. Electrification eliminates the emission of harmful gases at the ground level.
To reduce plastic waste, Indian Railways has introduced which of the following for serving tea at many stations?
Correct Answer: C. Kulhads (Clay cups)
The use of eco-friendly clay 'Kulhads' helps in reducing the reliance on single-use plastics. This initiative also provides employment opportunities to local potters across the country. Kulhads are biodegradable and add a traditional touch to the travel experience.
What is the purpose of 'Rainwater Harvesting' structures installed at railway stations?
Correct Answer: D. To recharge groundwater
The correct answer is 'To recharge groundwater'. Rainwater harvesting systems collect runoff from station roofs and platforms to replenish the water table. This is part of the broader 'Water Audit' strategy to manage water resources responsibly. Many major stations have now become water-surplus through these methods.
The Indian Railways is collaborating with which organization to install solar panels on unutilized railway land?
Correct Answer: A. BHEL
Bharat Heavy Electricals Limited (BHEL) has partnered with Railways to set up large-scale solar power plants. These plants feed power directly to the traction system via the overhead lines. This utilization of vacant land is a key part of the sustainability roadmap.
Which of the following describes the 'One Station One Product' scheme in a green context?
Correct Answer: C. Promoting local eco-friendly crafts
This scheme provides a platform for local artisans to sell indigenous, often handmade and sustainable products. By promoting local goods, the railways help reduce the carbon footprint associated with long-distance transport of goods. It also supports the local economy and traditional arts.
What kind of sensors are being used in railway station toilets to conserve water?
Correct Answer: D. Infrared sensors
Infrared-based automatic taps and flushes ensure that water flows only when needed. This significantly reduces water wastage in public facilities at busy stations. It is a key requirement for achieving higher green ratings from the IGBC.
The concept of 'Green Corridors' in Indian Railways primarily refers to?
Correct Answer: A. Sections where trains use only bio-toilets
Green corridors are specific sections where zero human waste is discharged onto the tracks because all trains are fitted with bio-toilets. The first such corridor was the Rameswaram-Manamadurai section in Tamil Nadu. It ensures that the tracks remain clean and free from foul smells.
