The essence of this chapter for last-minute revision: transport definitions, road and rail networks by region, the named trans-continental railways, sea routes and canals, inland waterways, air transport, pipelines and communications, with every named example. The full notes, with the complete explanation, are available separately.
1 Six definitions to learn
Learn by heartDefinition 1
Transport is a service or facility for the carriage of persons and goods from one place to the other using humans, animals and different kinds of vehicles.
Learn by heartDefinition 2
A transport network is several places (nodes) joined together by a series of routes (links) to form a pattern.
Learn by heartDefinition 3
Highways are metalled roads connecting distant places, built for unobstructed vehicular movement: 80 m wide, with separate traffic lanes, bridges, flyovers and dual carriageways.
Learn by heartDefinition 4
Border roads are roads laid along international boundaries. They integrate people in remote areas with major cities and play a role in defence.
Learn by heartDefinition 5
Trans-continental railways run across a continent and link its two ends, constructed for economic and political reasons to facilitate long runs in different directions.
Learn by heartDefinition 6
Cyberspace is the world of electronic computerised space, encompassed by the Internet such as the World Wide Web (www) – the electronic digital world for communicating or accessing information over computer networks without physical movement of the sender and the receiver.
2 Roads and highways
| Fact | Figure / example |
|---|---|
| Pack animals (before roads/rail) | Mules preferred in mountainous regions; camels used for caravan movement in deserts; bullocks used for pulling carts in India |
| Unmetalled vs metalled roads | Unmetalled roads become unmotorable in the rainy season; even metalled roads are seriously handicapped during heavy rains and floods |
| World’s motorable road length | About 15 million km; North America accounts for 33 per cent |
| North America highway density | About 0.65 km per sq km; every place within 20 km of a highway |
| Trans-Canadian Highway | Vancouver (British Columbia, west) to St. John’s City (Newfoundland, east) |
| Alaska Highway | Edmonton (Canada) to Anchorage (Alaska) |
| Trans-Continental Stuart Highway | Darwin (north coast) to Melbourne, via Tennant Creek and Alice Springs, Australia |
| Pan-American Highway | Connects South America, Central America and U.S.A.-Canada (largely built) |
| Russia’s highway hub | Moscow; important Moscow-Vladivostok Highway serves the region to the east |
| China’s highways | Tsungtso, Shanghai, Guangzhou and Beijing; a new highway links Chengdu with Lhasa |
| Golden Quadrilateral (India) | New Delhi, Mumbai, Chennai and Kolkata |
| Africa’s highways | Algiers to Conakry (Guinea); Cairo to Cape Town |
3 Railways by region
| Region | Key fact |
|---|---|
| World railway length | About 13 lakh km open for traffic |
| Railway gauges | Broad (more than 1.5 m), standard (1.44 m, used in U.K.), metre (1 m), and smaller gauges |
| Europe | About 4,40,000 km, mostly double/multiple-tracked; Belgium has the highest density, 1 km of railway per 6.5 sq km; Channel Tunnel (Euro Tunnel Group) connects London and Paris |
| Russia | Railways carry about 90 per cent of total transport; very dense west of the Urals; Moscow is the most important rail head |
| North America | One of the most extensive rail networks, nearly 40 per cent of the world’s total; used more for bulky freight (ores, grains, timber, machinery) than passengers |
| Canada | Railways in the public sector, spread over sparsely populated areas; transcontinental lines carry the bulk of wheat and coal |
| Australia | About 40,000 km; 25 per cent in New South Wales; Perth-Sydney line runs west-east |
| New Zealand | Railways mainly in the North Island, serving the farming areas |
| South America | Most dense in the Pampas (Argentina) and Brazil’s coffee-growing region, together 40 per cent of the continent’s route length; only trans-continental line: Buenos Aires-Valparaiso via the Uspallatta Pass (3,900 m) |
| Africa | Only 40,000 km despite being the second-largest continent; South Africa alone has 18,000 km, due to gold/diamond/copper mining; named routes: Benguela Railway, Tanzania Railway, the Botswana-Zimbabwe line, and the Blue Train (Cape Town-Pretoria) |
| Asia | Most dense in Japan, China and India; West Asia is the least developed |

| Panama Canal | Connects Atlantic (east) and Pacific (west) across the Panama Isthmus; about 72 km, six-lock system, ships rise/fall 26 m; shortens New York-San Francisco by 13,000 km |
6 Inland waterways
| Waterway | Key fact |
|---|---|
| Rhine | Navigable 700 km, Rotterdam to Basel; world’s most heavily used, over 20,000 ocean ships and 2,00,000 inland vessels a year |
| Danube | Navigable up to Taurna Severin; chief exports wheat, maize, timber, machinery |
| Volga | 11,200 km, drains into the Caspian Sea; Volga-Moscow Canal and Volga-Don Canal (to the Black Sea) |
| Great Lakes – St. Lawrence Seaway | Superior, Huron, Erie, Ontario linked by Soo and Welland Canals; goods trans-shipped at Montreal because of rapids |

| Optic fibre cables (OFC) | Transmit large data quantities rapidly, securely, virtually error-free |
| Satellites in daily life | Every time a cell phone is used to call a friend, send an SMS, or watch a programme on cable television, that is satellite communication |
| Internet | Formed as telecom merged with computers in the 1990s; connects about 1,000 million people in 100+ countries |
| Internet user growth | <50 million (1995) → 400 million (2000) → over 2 billion (2010) → about 5.4 billion (2023) |
| U.S.A.’s share of Internet users | Dropped from 66% (1995) to 25% (2005), as users shifted to developing countries |
| India’s satellites | Aryabhatt (19 Apr 1975), Bhaskar-I (1979), Rohini (1980), APPLE (19 Jun 1981) |
| Satellite cost/time invariance | Costs the same to communicate over 500 km as over 5,000 km via satellite |
8 Map work (CBSE 2026-27)
