The presence of efficient transport is imperative for any economy. It helps facilitate the movement of goods and services where they are required at the right time. The pace of development of a country depends on the production of goods and services and their movement from one place to another. Businesses may transport these commodities and services across three major areas of our planet: land, sea and air. Transport can also be categorised into the land, water and air transport based on these factors. Transport was able to accomplish this thanks to a similarly constructed communication infrastructure. Transport, communication, and trade are therefore mutually beneficial.

The  major modes of transportation include land, sea, and air. Transportation could also be categorised as land, marine or air transportation. Let us look at the detailed description mentioned in the Lifelines of National Economy Class 10 Solutions.


India has one of the largest road networks in the world, with a length of about 62.16 lakh kilometres. The following examples demonstrate the growing importance of automobile transportation over rail transportation:

  1. It costs substantially less to develop roads than rail.
  2. Roads can traverse steeper terrain and are easily incorporated into mountains such as the Himalayas.
  3. Roads can reach geographically more challenging regions that can’t be reached by rail.
  4. It additionally provides door-to-door service.
  5. Road travel is inexpensive.
  6. Road transportation links seaports, airports and railway stations.

According to their capacity, India’s roads are divided into six groups, as mentioned in the Lifelines of National Economy Class 10 Solutions.

  1. Golden Quadrilateral Super Highways: The Golden Quadrilateral is a network of highways that connects India’s four largest urban centres: Delhi, Kolkata, Chennai and Mumbai. The National Highway Authority of India is in charge of implementing these road projects (NHAI). The primary goal of these Super Highways is to shorten the time and distance between India’s megacities.
  2. National Highways: National Highways connect remote regions of the nation. The National Highways are a network of trunk roads built and maintained by the Central Public Works Department (CPWD). Between Delhi and Amritsar, the historical Sher-Shah Suri Marg is National Highway No. 1.
  3. State Highways: Roads connecting a state capital to many district headquarters are called State Highways. The State Public Works Department (PWD) builds and maintains these highways in states and union territories.
  4. District Roads: These routes connect the district headquarters to other locations. The Zila Parishad is in charge of maintaining these roads.
  5. Other Roads: This category includes rural highways that connect rural areas and villages with towns. The Pradhan Mantri Grameen Sadak Yojana gave these roads extra attention. Special measures are made under this strategy to ensure that every village in the country is connected to a large town by an all-season motorable road.
  6. Border Roads: The Border Roads Organization builds and maintains roads in the country’s border areas. This organisation was founded in 1960 to build strategic border routes in the northern and northeastern regions.
  7. Additionally, roads can be categorised according to the materials used in their construction, including the following:
  • Metalled roads can be formed of bitumen from coal, cement or even concrete. These are all-weather roads.
  • Unmetalled roads are rendered inoperable during the wet season.


In India, railways are the primary mode of freight and passenger transportation. Railways also enable people to engage in various activities such as business, sightseeing, pilgrimage and the movement of commodities over large distances. Railways in India connect the country’s economic life and drive the development of industry and agriculture.

In India, railroads are the main mode of transportation for delivering heavy loads and bulky goods over long and short distances. Railways have grown in importance in the Indian economy. The country’s railway network distribution pattern has been heavily influenced by physiographic, economic and administrative considerations. The northern plains, with their wide level area, high population density, and abundant agricultural resources, provided the best conditions for their expansion.

However, there are several issues with train transportation as well, some of which are listed below:

  1. Railroad lines across sandy plains are difficult to establish.
  2. Railway tracks are laid across low hills, gaps, and tunnels in the rough landscape of the peninsular region.
  3. The hilly regions of the Himalayas are also unfavourable for constructing railway lines due to higher elevation points of the surface, a low population and a lack of economic opportunities.
  4. To develop rail lines, bridge construction across large river beds is required.


The pipeline transportation network is a relatively new addition to India’s transportation landscape. These were once employed to deliver water to towns and industries. When solids are turned into slurry, the slurry can also be sent through a pipeline. Although installing pipelines has a significant upfront cost, ongoing maintenance is cheap. It eliminates delays or losses while transporting goods.

The pipeline system transports and distributes fluids via pipes, which are often underground. They transport water, crude oil, petroleum products, natural gas, fertiliser facilities and big thermal power plants.

This country has three significant pipeline networks, as mentioned in the Lifelines of National Economy Class 10 Solutions.

  1. From  Hazira in Gujarat to Jagdishpur in Uttar Pradesh
  2. Salaya in Gujarat to Jalandhar in Punjab
  3. Kanpur to the upper Assam oil fields (Uttar Pradesh)


Waterways are the most cost-effective mode of transportation. They are best suited for transporting large and bulky items. It is a low-emission and environmentally beneficial means of transportation.

India’s National Waterways, as mentioned in the Lifelines of National Economy Class 10 Solutions:

  1. The Ganga river between Allahabad and Haldia, N.W. No (1620 km).
  2. The Brahmaputra River between Sadiya and Dhubri, N.W. No (891 km).
  3. Kerala’s West Coast Canal, N.W. No. 3, (Kottapuram-Kollam, Udyogamandal and Champakara canals-205 km).
  4. N.W. No. 4 – Specific portions of the Krishna and Godavari rivers and the Kakinada-Puducherry canal length (1078 km).
  5. N.W. No. 5 – Specified Brahmani River lengths, along with the Matai River, the Mahanadi and Brahmani River Delta Channels, and the East Coast Canal (588 km).

14,500 km of inland waterways are available for navigation in India. Only 5685 km of them can be navigated by mechanical vessels.

Besides, India’s trade with foreign countries is conducted through ports along the coast. The sea transports 95% of the country’s trade volume (68% in value).

Major Sea Ports

With a 7,516.6-kilometre-long coastline, India has 12 major ports and 200 recognised non-major (minor/intermediate) ports. These large ports handle 95% of India’s international trade.

The list of India’s principal ports is as follows:

  1. Kandla in Kachchh was the first port to be established following independence. It is also known as the Deendayal Port.
  2. Mumbai is the most populous port, having a large natural and well-protected harbour.
  3. Mormugao port (Goa) is India’s leading iron ore exporting port.
  4. Mangalore port, located in Karnataka, handles iron ore exports.

  8. Visakhapatnam is the deepest and best-protected landlocked port.
  9. The Odisha port of Paradip specialises in the export of iron ore.
  10. Kolkata is a riverine port on the Indian subcontinent.
  11. Haldia port was built as a subsidiary port to relieve the growing load on the Kolkata port.


Air travel is the quickest, most comfortable and most prestigious means of transportation. Access to geographical locations such as steep mountains, harsh deserts, dense woods, and vast oceans has been facilitated by air transportation. In 1953, air transportation was nationalised. Air India offers both domestic and international air services. Oil and Natural Gas Corporation uses helicopter services from Pawan Hans Helicopters Ltd. for its offshore operations in challenging terrain and inaccessible locations. However, regular folks cannot afford to travel by plane.


Television, radio, the press, films and other forms of communication are widely used in India.

The Indian postal network is the world’s largest. It deals with both packages and personal written messages.

  1. First-class mail is airlifted between stations on land and in the air.
  2. Second-class mail includes book packs, registered newspapers and periodicals. Surface mail is used to carry them over land and ocean.

  2. India Radio Channel (Akashwani) transmits various programmes in national, regional and local languages.
  3. The national television network, Doordarshan, is one of the world’s largest terrestrial networks.
  4. India publishes a significant number of newspapers in over 100 different languages and dialects.

International Trade

Trade is the exchange of goods between individuals, states and countries. International trade refers to trade between two nations. It serves as the country’s economic gauge. The fundamental elements of trade are exports and imports. The difference between a country’s exports and imports is its trade balance.

  1. If the value of imports exceeds the value of exports, we have an unfavourable trade balance.
  2. A positive trade balance occurs when the value of exports exceeds the value of imports.

Products exported from India to other nations include precious stones and jewellery, chemicals and related products, agricultural and related products and so on. Products imported into India include crude oil and items, gemstones and jewellery, chemicals and associated products, basic metals, electrical goods, machinery, agriculture and related products.

India has developed as an international software giant, gaining significant foreign cash through the export of information technology.
