Q.27. How do physical and economic factors influence the distribution pattern of Indian railway network? Explain with suitable examples. [2004 & 2009]

Ans. The distribution pattern of the railway network in India has been greatly influenced by physical and economic factors.

Level lands of the Northern Plains of India with high density of population, rich agriculturalm resources and greater industrial activity have favoured the development of railways in this region. The region, therefore, has the densest network of railways in India. The rugged terrain of the Himalayan mountain region in the north and the north-eastern states with sparse population and lack of economic opportunities are unfavourable for construction of railway lines and railway network is lacking in these regions.

Sparsely populated sandy deserts of Rajasthan, hilly contiguous tracts of the Sahyadri swamps of Gujarat, forested tracks of Madhya Pradesh, Chhattisgarh, Orissa and Jharkhand, frequently flooded floodplains of Bihar and Assam have posed great difficulty in laying of railway lines. On account of the economic importance of the region, the Konkan Railways were developed in recent times along the west coast in spite of problems of sinking of tracks, landslides and need for construction of tunnels.

Q.3. Explain any four merits of pipleline transport in India. [2010]

Ans.

Pipelines are used for the transportation of crude oil, petroleum products and natural gas.
The merits of pipeline transportation in India are as follows :
(i) Pipelines help in the growth of refineries, petrochemicals, and fertiliser factories and big thermal power plants by providing raw materials directly from producing areas to the factories and plants.

(ii) Pipelines can take petroleum and natural gas to places far off from the oil and gas fields. They help in setting up of refineries in far inland locations to cater to the demands of markets inland. The refineries of Barauni, Mathura and Panipat were possible due to development of pipelines.

(iii) The initial cost of laying the pipelines may be high but subsequent running costs are nominal.

(iv) Pipelines transport petroleum and natural gas directly from producing areas to demand areas, hence, they rule out trans-shipment losses or delays.

Q.4. Why is road transport more useful than rail transport in India? Explain four reasons. [2009]

(i) Road transport is economical.
(ii) It provides door-to-door services.

Q.5. How do physical and economic factors influence the distribution pattern of the Indian railway network? Explain with examples. [2009]

Ans. The distribution pattern of the Railways network in the country has been largely influenced by physiographic and economic factors. The northern plains with their vast level land, high population density and rich agricultural resources provided the most favourable condition of its growth. While the Himalayan region with its high relief, sparse population and lack of economic opportunities have always retarded its growth and development.

Q.6. Explain, why is air transport preferred in north–eastern states of India? [2009]

Ans. The northeastern part of the country is marked with the presence of difficult hilly and\ mountainous terrain, dissected relief, large number of rivers, dense forest, heavy rainfall and frequent floods. International frontiers also mark this region. Air transport is the best mode of travel in these areas as airways can negotiate over geographical obstacles and political\ boundaries with great ease. Roads and railways cannot be properly laid out in such difficult terrain and heavy rainfall and frequent floods disrupt all other modes of transportation. Air transport is the only means of communication under such situations. They can access remote and inaccessible areas in these north-eastern states. They are the fastest and most comfortable means of transport. Domestic airlines have made special provisions to extend air service to the northeastern states at subsidised rates to meet the requirement of the common people. So, the airways are also within the financial reach of the common people in this region. On account of all these factors, airways is the preferred mode of transportation in the north eastern states of India.
