Frequently Asked Questions
Why are roadways preferred over railways in India?
Roadways are more flexible as they can be built on undulating terrain, provide door-to-door service, and have lower construction costs for short distances compared to railways.
What is the difference between domestic and international trade?
Domestic trade takes place within a country's borders using local currency, while international trade occurs between two or more countries and involves foreign exchange and custom duties.
Why is pipeline transport considered superior for petroleum and gas?
Pipelines eliminate losses during transit, reduce vehicular traffic on roads, and have low operational costs once installed, making them ideal for carrying liquids and gases over long distances.
