Question. Read the case/source given and answer the following questions.
The distribution pattern of the Railway network in the country has been largely influenced by Physiographic, economic and administrative factors. The Northern plains with their vast level land, high population density and rich agricultural resources provided the most favourable condition for their growth.
However, a large number of rivers requiring construction of bridges across their wide beds posed some obstacles.
In the hilly terrains of the peninsular region, railway tracts are laid through low hills, gaps or tunnels.
The Himalayan mountainous regions too are unfavourable for the construction of railway lines due to high relief, sparse population and lack of economic opportunities.
Likewise, it was difficult to lay railway lines on the sandy plain of Western Rajasthan, swamps of Gujarat, forested tracks of Madhya Pradesh, Chhattisgarh, Odisha and Jharkhand. The contiguous stretch of Sahyadri could be crossed only through gaps or passes (Ghats).
In recent times, the development of the Konkan railway along the West coast has facilitated the movement of passengers and goods in this most important economic region of India. It has also faced a number of problem such as sinking of track in some stretches and landslides.
(i) Which factors are largely responsible to influence the railway network in India? Write any one merit of railways.
Answer : Factors which are largely responsible to influence the railway network in India are physiographic, economic and administrative factors. An advantage or merit of railways is that they make it possible to conduct many activities like business, sightseeing, pilgrimage along with transportation of goods over longer distances.
(ii) Why is it difficult to construct railway lines in the Peninsular region and Himalayan region?
Answer : It is difficult to construct railway lines in the Peninsular region and Himalayan region because
◆ The Peninsular region and the Himalayan region are hilly and mountainous regions. Peninsular region has undulating topography where railway tracts are laid through low hills, gaps or tunnels.
◆ On the other hand the Himalayas have high relief, sparse population and lack of economic opportunities.
(iii) Although, the railways have become more important in our national economy still this transport is facing a number of problems. Why? State any two reasons.
Answer : It is true that railways have become more important in our national economy but still this transport is facing a number of problems which are
◆ Many passengers travel by trains without tickets. This incurs heavy loss of rail budget.
◆ People stop the trains, pull the chain unnecessarily and this causes heavy damage to the railway.
