- Such roads are part of the high-quality road network / expressways, often linked to National Highways. They are important because they ensure fast, smooth and safe movement of traffic and help in regional development.
Case Study 2 – Roadways in Hilly Areas Case-Based
A group of students from the plains visited a hill station in Himachal Pradesh. On the way, they noticed narrow, winding roads,
sharp bends and many hairpin curves. Heavy rainfall and landslides often blocked the roads. Despite these difficulties,
they saw trucks carrying food grains, fuel and construction material, as well as buses connecting remote villages to the nearby town.
Based on the above case, answer the following:
- Why is road construction in hilly areas more difficult and costly?
- How do these roads support the life of people in remote mountain villages?
- Name the special category of roads that connect extreme northern and north-eastern border areas of India.
Answers:
- Due to steep slopes, fragile rocks, frequent landslides and heavy rainfall, constructing and maintaining roads in hilly areas becomes difficult and costly.
- These roads supply essential goods like food grains, fuel and medicines and provide access to schools, hospitals and markets, thus supporting daily life and economic activities of people in remote villages.
- Such roads are known as Border Roads, constructed and maintained mainly by the Border Roads Organisation (BRO).
B. Railways – Case-Based Questions
Case Study 3 – Railways and Industrial Growth Case-Based
A steel plant located in the Chota Nagpur plateau region receives iron ore from nearby mines and coal from distant coalfields.
Finished steel products are supplied to different parts of the country. Most of this movement of raw materials and finished goods
takes place by rail. The railway line passing through this region is always busy with goods trains and passenger trains.
Read the case given above and answer the following questions:
- Why is the railway a suitable mode of transport for this steel plant?
- How do railways support industrial development in such regions?
- Mention any two problems faced by Indian Railways that can affect such industrial transport.
Answers:
- Railways can carry bulky and heavy goods like coal and iron ore over long distances at low cost, which makes them suitable for the steel plant.
- Railways supply raw materials to industries and carry finished products to markets, helping industries run continuously and reach customers across the country.
- Two problems are:
- Overcrowding and congestion on busy routes, and
- Old tracks and equipment that may cause delays and accidents.
Case Study 4 – Distribution of Railway Network Case-Based
Rohan compared two maps – one showing the railway network of India and the other showing its relief features.
He observed that the northern plains have a dense railway network, while the Himalayan and desert regions have sparse railway lines.
He also noticed that some coastal areas and states with high population density have better railway connectivity.
Study the case and answer:
- Why does the northern plain have a dense railway network?
- Give one physical and one economic reason for sparse railway network in certain regions.
- How does population density influence the development of railway lines?
Answers:
- The northern plain has level land, fertile soil and high population, which make construction easy and generate high demand for rail transport, leading to a dense railway network.
-
Physical reason: Hilly terrain or deserts make construction difficult and expensive.
Economic reason: Low level of industrial and agricultural development reduces demand for rail transport. - Regions with high population density need more transport facilities for passengers and goods, so railways are developed to meet this demand.
C. Pipelines – Case-Based Questions
Case Study 5 – Transporting Petroleum by Pipelines Case-Based
India imports large quantities of crude oil through its western coastal ports. From there, the oil has to be taken to inland refineries
located far away from the coast. Earlier, this was done mainly by rail tankers and road tankers. Now, long underground pipelines have been
laid to carry crude oil directly from ports to refineries and finished products to distribution centres.
Read the passage and answer:
- Explain one disadvantage of using rail and road tankers for transporting petroleum.
- State two advantages of using pipelines instead.
- Give one example of an important oil or gas pipeline in India.
Answers:
- Using rail and road tankers can be costly, time-consuming and may increase the risk of accidents and leakage during transport.
- Two advantages of pipelines:
- They provide a continuous and reliable flow of petroleum over long distances.
- They are more economical and safer in the long run and reduce congestion on roads and railways.
- One example is the Hazira–Vijaipur–Jagdishpur (HVJ) gas pipeline or the Salaya–Mathura oil pipeline.
Case Study 6 – Pipelines and Fertiliser Production Case-Based
A fertiliser plant in Uttar Pradesh receives natural gas from a distant gas field through an underground pipeline.

On the basis of the above passage, answer the following questions:
- Why are seaports called the ‘gateways of international trade’?
- Name any two major seaports of India – one on the eastern coast and one on the western coast.
- How do ports support the national economy?
Answers:
- Seaports are called ‘gateways of international trade’ because most of India’s imports and exports are handled through them and they connect India with the rest of the world.
- Eastern coast – Kolkata (with Haldia) or Chennai; Western coast – Mumbai, Kandla or Cochin.
- Ports earn foreign exchange, create employment, encourage industries that depend on import and export and help in overall economic growth.
E. Airways – Case-Based Questions
Case Study 9 – Air Transport in Difficult Terrain Case-Based
