Chapter 7: Transport and Communication

Introduction

Natural resources, economic activities and markets are rarely found in one place. Transport, communication and trade link producing centres with consuming centres. Transport carries persons and goods over land, water and air, and pipelines carry petroleum, natural gas and liquefied ores. A transport network is several places (nodes) joined by a series of routes (links) to form a pattern. In a well-managed system the modes complement each other:

  • ocean freighters handle international goods;
  • roads are cheaper and faster over short distances and door-to-door;
  • railways suit bulky goods over long distances within a country;
  • airways move high-value, light and perishable goods.

    • Key Concepts

    1. Land Transport

  • Railways: the first public railway opened in 1825 between Stockton and Darlington in England. The internal combustion engine revolutionised road transport.

    • Roads are the most economical mode for short distances and give door-to-door service.

  • The world's motorable road length is only about 15 million km, and North America has 33 per cent of it.

    • Highways are metalled roads about 80 m wide, with separate lanes and flyovers.

  • North America: highway density is about 0.65 km per sq km, and every place is within 20 km of a highway.
  • Trans-Canadian Highway: Vancouver to St. John's City.
  • Alaskan Highway: Edmonton to Anchorage.
  • Pan-American Highway: will link South America, Central America and USA–Canada.
  • Stuart Highway: Darwin to Melbourne, via Tennant Creek and Alice Springs.
  • India: the Golden Quadrilateral links Delhi, Mumbai, Chennai and Kolkata.

    • Railways carry bulky goods and passengers over long distances.

  • Gauges: broad (more than 1.5 m), standard (1.44 m, used in the UK) and metre (1 m). There are about 13 lakh km of railways in the world.
  • Europe: about 4,40,000 km. Belgium has the highest density, 1 km of railway per 6.5 sq km. The Channel Tunnel links London and Paris.
  • Russia: railways carry about 90 per cent of total transport, and Moscow is the chief rail head.
  • North America: nearly 40 per cent of the world's rail network, used mainly for freight.
  • South America: the only trans-continental line runs from Buenos Aires to Valparaiso through the Uspallata Pass at 3,900 m.

    • Trans-continental railways

  • Trans-Siberian: St Petersburg to Vladivostok, 9,332 km. It is the longest double-tracked, electrified trans-continental railway in the world.
  • Trans-Canadian: Halifax to Vancouver, 7,050 km, built in 1886. It is Canada's economic artery; wheat and meat are its main exports.
  • Australian Trans-Continental: Perth to Sydney, via Kalgoorlie, Broken Hill and Port Augusta.
  • Orient Express: Paris to Istanbul. London to Istanbul now takes 96 hours instead of 10 days by sea.

    • 2. Water Transport

    Water transport needs no route construction, only ports at the two ends. It is cheaper because water's friction is far less than land's.

    Sea routes

  • Northern Atlantic: links north-eastern USA and north-western Europe. It carries one-fourth of world foreign trade, making it the busiest route, the Big Trunk Route.
  • Mediterranean–Indian Ocean: serves more countries and people than any other route, via Port Said, Aden, Mumbai, Colombo and Singapore.
  • Cape of Good Hope and Southern Atlantic routes link Western Europe with Africa, Australasia and South America.
  • North Pacific: routes converge at Honolulu, and the Great Circle links Vancouver and Yokohama.
  • South Pacific: via the Panama Canal to Australia and New Zealand. Panama to Sydney is 12,000 km.

    • Shipping canals

  • Suez Canal: built in 1869 in Egypt, from Port Said to Port Suez, linking the Mediterranean and the Red Sea. It is a sea-level canal without locks, about 160 km long and 11–15 m deep. About 100 ships a day cross it, each taking 10–12 hours.
  • Panama Canal: Atlantic to Pacific, between Panama City and Colon. It is about 72 km long with a six-lock system. It shortens the New York–San Francisco sea distance by 13,000 km and is vital to Latin America, though less significant economically than Suez.

    • Inland waterways depend on channel width and depth, continuity of flow, and technology.

  • Rhine: navigable for 700 km from Rotterdam to Basel. It is the world's most heavily used waterway, carrying 20,000 ocean ships and 2,00,000 inland vessels a year.
  • Volga: navigable for 11,200 km and drains into the Caspian Sea.
  • Great Lakes–St Lawrence Seaway: connected by the Soo and Welland canals.
  • Mississippi–Ohio: large steamers can reach Minneapolis.

    • 3. Air Transport

  • It is the fastest mode but very costly, and often the only way to reach inaccessible areas.
  • No place in the world is more than 35 hours away.
  • The UK pioneered commercial jets, while the USA developed post-war civil aviation.
  • More than 250 commercial airlines operate, and supersonic aircraft cross London–New York in 3.5 hours.
  • Inter-continental routes: there is an east–west belt in the Northern Hemisphere, and the USA accounts for 60 per cent of the world's airways.
  • Air services are limited in Africa, Asiatic Russia and South America.

    • 4. Pipelines

  • Pipelines carry water, petroleum, natural gas and LPG. New Zealand even pipes milk from farms to factories.
  • Big Inch carries petroleum from the Gulf of Mexico to the north-eastern USA.
  • About 17% of US freight (tonne-km) moves by pipeline.
  • The proposed Iran–Pakistan–India pipeline will be the world's longest.

    • 5. Communications

  • Optic fibre cables carry large volumes of data rapidly, securely and virtually error-free.
  • Digitisation in the 1990s merged telecom with computers to form the Internet.
  • Satellite communication grew from the 1970s. It makes communication cost the same over 500 km as over 5,000 km.
  • India's satellites: Aryabhatt (19 April 1975), Bhaskar-I (1979), Rohini (1980) and APPLE (19 June 1981).
  • Cyberspace: internet users rose from under 50 million (1995) to about 400 million (2000), over 2 billion (2010) and about 5.4 billion (2023). E-mail, e-commerce, e-learning and e-governance have made the global village a reality.

    • Map Work

  • Trace the Trans-Siberian, Trans-Canadian, Union Pacific, Australian and Orient Express lines.
  • Trace the six sea routes.
  • Mark the Suez and Panama canals.
  • Mark the Rhine, Volga, Danube and Mississippi waterways and the Great Lakes.

    • Key-Facts Sheet

  • The first public railway was Stockton–Darlington in 1825.
  • The Trans-Siberian is 9,332 km; the Trans-Canadian is 7,050 km (1886).
  • Suez: 1869, 160 km, no locks. Panama: 72 km, six locks.
  • The USA has 60% of the world's airways.

    • Board Exam Focus

    MCQs in the exercises:

  • The Stuart Highway runs from Darwin to Melbourne.
  • The Big Trunk Route runs through the North Atlantic.
  • Big Inch carries petroleum.
  • The Channel Tunnel links Paris and London.

    • Outline: Advantages of water transport (30 words).

  • No route construction needed, only ports.
  • Low friction.
  • Low energy cost.
  • Cheapest for bulky goods over long distances.

    • Outline: "Modes complement each other".

  • Ocean for international trade.
  • Road for short distances and door-to-door delivery.
  • Rail for bulky goods over long distances.
  • Air for light, perishable, high-value goods.

    • Outline: Regions with dense airway networks.

  • Eastern USA, Western Europe and South-east Asia.
  • Name the nodal cities.
  • Contrast with areas that lack air services.

    • Key Terms

  • Transport network (परिवहन जाल): nodes joined by links.
  • Node (नोड): a meeting point of routes.
  • Highway (महामार्ग): a metalled long-distance road.
  • Border roads (सीमांत सड़कें): roads along international boundaries.
  • Trans-continental railway (पार-महाद्वीपीय रेलमार्ग): a line linking the two ends of a continent.
  • Big Trunk Route (वृहद् ट्रंक मार्ग): the North Atlantic sea route.
  • Inland waterway (आंतरिक जलमार्ग): river, canal or lake transport.
  • Pipeline (पाइपलाइन): a pipe carrying liquids and gases.
  • Optic fibre cable (प्रकाशीय तंतु केबल): a high-speed data line.
  • Cyberspace (साइबर स्पेस): the electronic digital world.
  • Global village (वैश्विक गाँव): a world connected by communication.

    • Common Mistakes

  • Giving the Panama Canal as lock-free. It is Suez that has no locks; Panama has six.
  • Naming the Mediterranean route as the Big Trunk Route. It is the Northern Atlantic.
  • Stretching the Trans-Canadian from Montreal. It runs from Halifax to Vancouver.
  • Writing that Big Inch carries LPG. It carries petroleum.
  • Mixing up the highway endpoints: Alaskan is Edmonton–Anchorage; Trans-Canadian is Vancouver–St. John's.

    • 💡 Key Learning Points

    • ✓Explain the role of transport and communication, and how modes complement each other.
    • ✓Describe road, highway and railway networks, including the major trans-continental railways.

    👨‍🏫 Teaching Tips

    • →Hand out outline maps and have students trace each trans-continental railway with its terminal cities as it is taught.
    • →Use a 'mode selection' game: give cargo such as flowers, iron ore, crude oil and a parcel to the next town, and ask for the best mode.
    • →Compare Suez and Panama with a quick two-column comparison (year, length, locks, oceans joined).
    • →Show a globe to demonstrate why the Great Circle shortens the Vancouver–Yokohama route.
    • →Build an internet-growth timeline (1995, 2000, 2010, 2023) and discuss the global village.
    • →Link India's satellite milestones (Aryabhatt 1975 onward) to daily uses such as weather forecasts.
    • →Revise all five textbook MCQs with 'why the others are wrong' explanations.
