Start here: why this chapter matters
In simple wordsYour morning tea, toothpaste and newspaper all travelled to you — the tea from an Assam garden by road, rail and ship, the news by satellite and phone. Transport moves things; communication moves ideas. A country's roads, railways, ports and networks are its arteries and nerves.
The earlier chapters located India's people, farms, water and minerals. This chapter shows how they are connected: how produce reaches markets, how people move, and how messages travel. NCERT covers land (roads, railways, pipelines), water (inland, oceanic), air, and communication (personal and mass, including satellites).
- Builds on Fundamentals of Human Geography Chapter 7 (Transport and Communication) — world routes, canals, ocean lanes. This chapter is India's version: National Highways, railway zones, the Konkan Railway, National Waterways, Indian ports.
- Builds on Chapter 5 (Minerals and Energy): oil and gas pipelines and refineries; and Chapter 2 (Human Settlements): ports and transport towns.
- Leads into Chapter 8 (International Trade), which depends on ports and sea routes.
- UPSC: GS1 (infrastructure and settlement), GS3 (infrastructure — roads, railways, ports, airports, PPP, logistics). Prelims has asked National Highways, railway zones, the Konkan Railway, ports and satellites; Mains asks urban transport, UDAN, Gati Shakti, PPP in railways and airports.

Reading the chapter-opening photograph (page 75)A busy multi-lane city road lined by tall buildings, with cars, auto-rickshaws and a foot-over-bridge for pedestrians. It shows how road traffic dominates Indian cities — and why metros and better public transport matter (Mains 2014, 2019).

1. Road transport
In simple wordsRoads are like a family tree: the National Highways are the trunk, State Highways the main branches, district roads the twigs, and village roads the leaves. The trunk is thin in length but carries most of the weight.
India has the world's second-largest road network, about 62.16 lakh km (MoRTH Annual Report 2020–21). Roads carry about 85 per cent of passengers and 70 per cent of freight and suit shorter distances. Before World War II modern roads were few; the first serious plan was the Nagpur Plan (1943), not implemented for lack of coordination between princely States and British India; after Independence came the twenty-year road plan (1961). Roads still concentrate around cities; rural and remote areas have the least connectivity.
Reading NCERT's ‘Do you know’ on the Grand Trunk road (page 76)Sher Shah Suri built the Shahi (Royal) road from the Indus valley to the Sonar valley in Bengal to consolidate his empire. The British renamed it the Grand Trunk (GT) road, linking Calcutta and Peshawar; today it runs from Amritsar to Kolkata.
Reading NCERT Table 7.1 — India Road Network 2020 (page 77)National Highways 1,36,440 km; State Highways 1,76,818 km; other roads 59,02,539 km; total 62,15,797 km (the parts add exactly). NH grew from 19,700 km in 1951 to 1,36,440 km in 2020 — nearly seven times.
| Category | Who / what (NCERT) |
|---|---|
| National Highways | Built and maintained by the Centre; inter-State movement, defence movement in strategic areas; link State capitals, big cities, ports, railway junctions. NHAI, operationalised 1995, develops, maintains and operates them |
| State Highways | Built and maintained by States; link State capitals with district headquarters and towns; connect to NHs |
| District roads | Link district headquarters with other important nodes in the district |
| Rural roads | About 80% of road length; density varies with terrain; Pradhan Mantri Gram Sadak Yojana (Fig. 7.2) |
| Other roads | Border roads (BRO, May 1960) and international highways to neighbouring countries |
⤵ How the road system is organised by responsibility
Centre (MoRTH + NHAI)National Highways: GQ, NS–EW corridors, Bharatmala economic corridors
StatesState Highways: capital ↔ district headquarters
Districts and rural bodiesdistrict roads and rural roads (PMGSY)
BROstrategic roads, snow clearance, tunnels in the north and north-east
International highwayslinks with neighbours — Delhi–Lahore bus, Aman Setu
Reading NCERT's ‘National Highways Development Projects’ and ‘Bharatmala’ boxes (pages 77, 79)
- Golden Quadrilateral: 5,846 km, 4/6 lanes, linking Delhi–Mumbai–Chennai–Kolkata; cuts time, distance and cost between the metros.
- North–South corridor: Srinagar–Kanniyakumari, 4,076 km, including the Kochi–Salem spur. East–West corridor: Silchar (Assam)–Porbandar (Gujarat), 3,640 km.
- Bharatmala Pariyojana: about 26,000 km of economic corridors that, with GQ and NS–EW, will carry most road freight; ring roads, bypasses and elevated corridors to decongest cities and improve logistics.
Reading the road photographs (Figs 7.1–7.5)
- Fig. 7.1: nomads with laden ponies in rain at Srinagar while the 300-km Srinagar–Jammu and 434-km Srinagar–Leh highways are shut by snow; beside it, a jam of buses and cars in Delhi — two faces of road transport: weather-closed mountain roads and congested city roads.
- Fig. 7.2: a jeep on a hill road built under PMGSY — rural connectivity.
- Fig. 7.3: tourists at Khardung La in Ladakh beside a marker claiming the ‘world’s highest motorable road’, amid snow.
- Fig. 7.4: the Lahore–Delhi bus at the Wagah border; Fig. 7.5: crowds at Aman Setu on the Baramula–Muzaffarabad route — international roads as instruments of goodwill.
Reading NCERT's ‘Do you know’ on the Atal Tunnel (page 78)The Atal Tunnel (9.02 km), built by BRO at about 3,000 m in the Pir Panjal range, links Manali with the Lahaul–Spiti valley all year; earlier the valley was cut off for about six months by snow.
NCERT details to watch
- NCERT calls Atal Tunnel the ‘world's longest highway tunnel’; it is the longest highway tunnel above 10,000 feet — much longer road tunnels exist at lower altitudes (Beyond NCERT).
- The Khardung La sign's claim is old; BRO's road over Umling La (about 5,800 m, eastern Ladakh) was recognised in 2021 as the world's highest motorable road (Beyond NCERT).
- NHAI is described as under the ‘Ministry of Surface Transport’; today it is the Ministry of Road Transport and Highways.
- The East–West corridor runs Silchar–Porbandar, not Dibrugarh–Surat (UPSC 2023 statement 1 false).
- NH share of traffic is 40% in NCERT; UPSC 2002's ‘45%’ statement was accepted in that year's key — numbers drift with time.
- NH numbers changed in 2010: old NH 1 (Delhi–Amritsar), NH 2 (Delhi–Kolkata), NH 7 (Varanasi–Kanyakumari, then the longest); now NH 44 (Srinagar–Kanyakumari) is the longest (Beyond NCERT).
2. Rail transport
In simple wordsIf roads are India's capillaries, railways are its main arteries: they carry huge loads over long distances cheaply. Gandhi said they brought people of different cultures together for the freedom struggle — millions still meet on the same train every day.
Indian Railways began in 1853 with a 34-km line from Bombay to Thane. It is the country's largest government undertaking and one of the world's longest networks — 67,956 km (Railway Yearbook 2019–20) — divided into 17 zones to ease management. Steam engines have been replaced by diesel and electric ones, raising speed and haulage and cleaning station environments; metro rail and CNG buses are cutting urban air pollution.
| Zone | Headquarters | Zone | Headquarters |
|---|---|---|---|
| Central | Mumbai CST | North Western | Jaipur |
| Eastern | Kolkata | Southern | Chennai |
| East Central | Hajipur | South Central | Secunderabad |
| East Coast | Bhubaneswar | South Eastern | Kolkata |
| Northern | New Delhi | South East Central | Bilaspur |
| North Central | Prayagraj | South Western | Hubli |
| North Eastern | Gorakhpur | Western | Mumbai (Churchgate) |
| North East Frontier | Maligaon (Guwahati) | West Central | Jabalpur |
| Metro Railway | Kolkata |
Reading NCERT Table 7.2 — Railway Zones and Headquarters (page 79)Seventeen zones including Metro Railway, Kolkata. Two cities host two zones each: Mumbai (Central at CST, Western at Churchgate) and Kolkata (Eastern, South Eastern — plus Metro). Several headquarters are not State capitals — Hajipur, Gorakhpur, Bilaspur, Hubli, Jabalpur, Secunderabad, Maligaon — favourite exam traps (UPSC 2005, 2006). Beyond NCERT: a new South Coast Railway zone at Visakhapatnam was announced in 2019.
Reading NCERT's ‘Konkan Railway’ box (page 80)Built in 1998, the 760-km line links Roha (Maharashtra) and Mangalore (Karnataka); it crosses 146 rivers and streams, nearly 2,000 bridges and 91 tunnels, including a tunnel of nearly 6.5 km that NCERT calls ‘Asia's largest’. Maharashtra, Goa and Karnataka are partners.
⤵ How India's railway geography developed (NCERT)
Colonial linestowns, raw-material areas, plantations, hill stations, cantonments — built for exploiting resources
After 1947routes extended to other areas; gauge conversion; diesel and electric traction
LandmarkKonkan Railway (1998): direct Mumbai–Mangaluru link along the west coast
Gapsnetwork thin in hill States, the north-east, central India and Rajasthan
Exam traps
- North Western Railway HQ is Jaipur, not Jodhpur (UPSC 2005); South Eastern Railway HQ is Kolkata, not Bhubaneswar (UPSC 2006) — Bhubaneswar is East Coast.
- Konkan Railway runs through Maharashtra, Goa, Karnataka — not Kerala (UPSC 1999); the states that benefit most include Kerala too (UPSC 1998).
- ‘Asia's largest tunnel’ (6.5 km, Karbude) was India's longest railway tunnel when built; the Pir Panjal (Banihal–Qazigund) rail tunnel of about 11 km, opened in 2013, is longer (Beyond NCERT).
- Broad gauge 1.676 m; metre 1 m; narrow 0.762 or 0.610 m.
- Railway and telegraph came under Lord Dalhousie (UPSC 1989); Calcutta had India's first underground metro (UPSC 1979).
Beyond NCERT
- Dedicated Freight Corridors (Western: Dadri–JNPT; Eastern: Ludhiana–Sonnagar) separate freight from passenger traffic. Kavach is an indigenous automatic train-protection system developed by RDSO — not with Germany (UPSC 2025).
- Mains: PPP in redevelopment of railway stations (2022); urban mass transport and the National Urban Transport Policy's ‘moving people, not vehicles’ (2014, 2019).
3. Water transport: inland waterways and ports
In simple wordsA loaded boat floats on its own — no fuel spent lifting it — so water is the cheapest way to move heavy, bulky goods. But a river needs enough water all year, and India takes much of it for irrigation.
Water transport is the cheapest mode, suits heavy and bulky goods, and is fuel-efficient and eco-friendly. Inland waterways were the chief mode before railways but lost out to road and rail, and diversion of river water for irrigation left long stretches non-navigable. India has 14,500 km of navigable waterways — rivers, canals, backwaters, creeks — but they carry only about 1% of transport. The Inland Waterways Authority of India (1986) develops National Waterways; the National Waterways Act, 2016 declared 111 NWs (including the original five).
Reading NCERT Table 7.3 and Figure 7.7 — National Waterways (page 81)
- NW 1 (Ganga, Prayagraj–Haldia, 1,620 km): navigable by mechanised boats up to Patna, ordinary boats up to Haridwar; developed in three parts — Haldia–Farakka 560, Farakka–Patna 460, Patna–Prayagraj 600 km.
- NW 2 (Brahmaputra, Sadiya–Dhubri, 891 km); steamers ply to Dibrugarh (1,384 km), shared by India and Bangladesh.
- NW 3 (Kottapuram–Kollam, 205 km): 168 km of the West Coast Canal + Champakara canal (14 km) + Udyogmandal canal (23 km). Fig. 7.7 shows a snake-boat race on the canal and a sketch from Kottapuram via Kochi (0–30 km), Alappuzha (30–92 km) to Kollam (92–168 km), passing Vembanad lake and Kayamkulam kayal.
- NW 4: Godavari and Krishna stretches with the Kakinada–Puducherry canals (1,078 km). NW 5: Brahmani, Matai, the Mahanadi–Brahmani delta channels and the East Coast canal (588 km).
Reading NCERT Figure 7.6 — River navigation in the North-east (page 80)A crowded wooden ferry on a wide river, people packed on the roof — for many riverine communities in Assam, boats are still everyday public transport, and the photo hints at the safety risks of overcrowding.
Kerala's backwaters (kayal) give cheap transport and draw tourists; the Nehru Trophy Boat Race (Vallamkali) is held there. IWAI has identified 10 more waterways for upgrading.
Oceanic routes. India's coastline is about 7,517 km including islands, served by 12 major and about 200 minor ports. About 95 per cent of foreign trade by volume and 70 per cent by value moves by sea; ocean routes also link the islands with the mainland.
⤵ Why inland waterways declined — and the revival plan
Before railwaysrivers were the chief transport (cheap, bulk)
Competitionfaster road and rail
Less waterirrigation diversions; seasonal low flow, siltation
Result≈ 1% share despite 14,500 km navigable
RevivalIWAI (1986) · 111 National Waterways (2016) · tourism (Kerala) · Beyond NCERT: Jal Marg Vikas on NW 1
Exam traps
- NW 1 = Ganga, Haldia–Prayagraj (exercise Q1-ii); NW 2 = Brahmaputra; NW 3 = West Coast Canal.
- Kolkata (on the Hugli) is India's riverine major port (UPSC 1998); Dahej is a non-major port (2009); Marmagao grew on iron-ore exports (1979).
- Kamarajar (Ennore) was the first major port registered as a company; Mundra is the largest private port (UPSC 2023 — only two pairs right).
- Beyond NCERT: India's coastline was re-measured with a new method at about 11,098 km (2024–25); exams based on NCERT still use 7,517 km.
Beyond NCERTSagarmala (2015) aims at port-led development: port modernisation, port connectivity, port-linked industry and coastal communities (UPSC 2026). Mains 2016 asked the problems and prospects of inland water transport: seasonal depth, siltation, terminals, multimodal links, and the cost advantage for bulk cargo.
4. Air transport and pipelines
In simple wordsPlanes beat distance and mountains; pipelines beat everything else for liquids and gas — once laid, they deliver day and night with no trucks on the road. Each is ideal for one job and costly for others.
Air transport is the fastest mode — essential for a vast country with diverse terrain. It began in 1911 with a 10-km airmail flight between Prayagraj and Naini; real growth came after Independence. The Airports Authority of India provides air traffic and aeronautical communication services. Pawan Hans runs helicopter services in hilly areas, for tourists in the north-east, and for the petroleum sector.
Reading NCERT's ‘Do you know’ on UDAN (page 82)UDAN — Ude Desh ka Aam Nagrik — the Regional Connectivity Scheme of the Ministry of Civil Aviation, called a first-of-its-kind scheme globally: make flying affordable for ordinary citizens by encouraging airlines, through policy and incentives, to fly regional and remote routes. Beyond NCERT: launched in 2016, first flight 2017; Mains 2024 asked about its achievements.
Pipelines are the most convenient, efficient way to move liquids and gases over long distances; even solids can travel as slurry. Oil India Limited (incorporated 1959) built Asia's first cross-country pipeline, 1,157 km from Naharkatiya (Assam) to Barauni (Bihar), extended to Kanpur in 1966. GAIL (1984) built the 1,700-km Hazira–Vijaipur–Jagdishpur (HVJ) gas pipeline linking Mumbai High and Bassein gas to fertiliser, power and industrial plants in western and northern India. Cross-country gas pipelines have grown more than ten times, to about 18,500 km, towards a national gas grid of over 34,000 km.
| Pipelines: advantages | Pipelines: disadvantages |
|---|---|
| Cheap to run once built; continuous flow; little energy loss | High initial cost; fixed route — no flexibility |
| Reach difficult terrain; no road congestion; few accidents | Leaks hard to detect and repair; theft and sabotage risk |
| Low pollution; can carry slurry | Capacity cannot be changed easily; one product line |
Exam traps
- First airmail: 1911, Allahabad (Prayagraj)–Naini.
- Cochin was the first airport owned by a public limited company (UPSC 2005); Donyi Polo (Itanagar) and Kushinagar are greenfield airports, Vijayawada is not (UPSC 2024).
- The first cross-country pipeline carried crude oil (OIL), not gas; HVJ is GAIL's gas pipeline.
5. Communication networks
In simple wordsOnce a message travelled as fast as a horse; now it crosses India in a fraction of a second. Drum beats, smoke signals and runners gave way to post, telegraph, radio, TV, satellites and the internet.
Messages were once carried by drums, smoke, fire, runners and animals; the means of communication were also the means of transport. The post office, telegraph, printing press, telephone and satellites made communication faster and easier. NCERT groups modern communication into personal and mass systems.
- Personal: the internet is the most effective — e-mail, access to knowledge, e-commerce and money transactions at low cost; widely used in cities.
- Radio: started 1923 by the Radio Club of Bombay; under government control in 1930 (Indian Broadcasting System); All India Radio 1936; Akashvani 1957; information, education, entertainment and special bulletins.
- Television: began in Delhi in 1959; more centres after 1972; separated from AIR as Doordarshan in 1976; after INSAT-1A, Common National Programmes reached remote rural areas.
- Satellites: continuous, synoptic views for weather, disasters and border surveillance. INSAT (1983): telecommunication, meteorology and data. IRS: from IRS-1A (March 1988); data in several spectral bands for natural-resource management, processed at the National Remote Sensing Centre, Hyderabad. India also built the PSLV.

NCERT's in-text questions and activities — short answers
Collect information about National Highway numbers (old and new) from morth.nic.in. (page 76)
In 2010 NHs were renumbered on a grid: north–south routes even numbers increasing west to east, east–west routes odd numbers increasing north to south. E.g. old NH 7 (Varanasi–Kanyakumari) is now part of NH 44 (Srinagar–Kanyakumari); old NH 2 is NH 19; old NH 8 is NH 48 (Beyond NCERT).
Why is rural road density very low in hilly, plateau and forested areas? Why does quality deteriorate away from urban centres? (page 77)
Rugged terrain, steep slopes, landslides and dense forest raise cost; settlements are small and scattered, so traffic is low; forest laws restrict construction. Away from cities, funds, maintenance and traffic-generated revenue fall, and heavy rain damages unmaintained roads.
Why have Bengaluru and Hyderabad in the south and Delhi, Kanpur and Patna in the north emerged as important nodes? (page 79)
They sit where national highways and railway trunk lines meet, are large administrative, industrial or IT centres, and have major airports — so routes converge on them (Delhi on the GQ, Kanpur and Patna on the Ganga plain trunk lines, Bengaluru and Hyderabad on the NS corridor).
Which cities of India have metro rail? Discuss. (page 80)
Kolkata (first, 1984), Delhi, Bengaluru, Mumbai, Chennai, Kochi, Hyderabad, Lucknow, Jaipur, Ahmedabad, Nagpur, Pune, Kanpur, Agra, Indore, Bhopal and others (Beyond NCERT). Metros cut congestion and pollution and save travel time.
NCERT exercise — answer outlines
Try each question yourself first, then open the outline to compare. The three multiple-choice questions are in the self-check below.
Which activity does transportation convey? Name three major modes of transportation. (30 words)
It moves goods, people and commodities from places of production or availability to places of use — a tertiary service linking producers and consumers. Modes: land (road, rail, pipeline), water (inland, oceanic), air.
Discuss advantages and disadvantages of pipeline transportation. (30 words)
Advantages: cheapest for liquids and gases over long distances; continuous flow; low running cost; crosses difficult terrain; little pollution; can carry slurry. Disadvantages: high initial cost, fixed routes, inflexible capacity, leaks hard to detect and repair, security risk.
What do you mean by ‘communication’? (30 words)
The exchange of messages, ideas and information between persons or places — personal (letter, phone, internet) or mass (radio, TV, newspapers, satellites).
Which are the chief means of transportation in India? Discuss the factors affecting their development. (150 words)
Means: roads (≈ 62 lakh km; 85% passengers, 70% freight), railways (67,956 km; long-haul bulk), water (inland 14,500 km; ports for ≈ 95% of trade by volume), air (fastest; UDAN), pipelines (oil, gas).
Factors: relief (plains dense networks; Himalaya, NE, plateaus sparse — BRO, tunnels); climate (snow closes Srinagar–Leh; floods damage roads); rivers (perennial flow for waterways; irrigation diversion reduced them); economy (industries, mines, ports, cities attract routes); population and settlements (dense plains vs scattered hills); history (colonial lines to ports and resources); policy and capital (NHAI, Bharatmala, Konkan Railway, IWAI, UDAN, PMGSY); strategy (border roads).

Give a detailed account of the development of railways in India and highlight their importance. (150 words)
Development: 1853 Bombay–Thane (34 km); colonial lines to ports, raw materials, plantations, hill stations, cantonments; after 1947 extension to new areas, gauge conversion (broad 63,950 of 67,956 km), diesel and electric traction, 17 zones, Konkan Railway (1998), metro rail.
Importance: cheap mass transport for long distances; carries bulk freight (coal, ore, grain, cement); integrates markets and regions; employs millions; unites people (Gandhi's remark); aids defence and disaster relief; greener than road per tonne-km.
Issues: thin networks in hills, NE, central India and Rajasthan; congestion; finances.
Diagram: gauges or the Konkan schematic.

Reach: ≈ 62 lakh km, door-to-door; 85% of passengers, 70% of freight.
Roles: link farms to markets (rural roads, PMGSY) — better prices, less wastage; feed railways, ports and airports; carry short-haul goods cheaply; tourism; jobs in construction and trucking; access to schools and hospitals; strategic and border integration (BRO, Atal Tunnel); regional balance (NS–EW, Bharatmala economic corridors cut logistics costs).
NH: 2% of length, 40% of traffic — GQ, NS–EW.
Problems: urban concentration, poor rural quality, congestion, accidents.
Conclude: roads are the base of a multimodal system (Gati Shakti, Beyond NCERT).

- East–West corridor is Silchar–Porbandar, not Dibrugarh–Surat.
- NWR HQ = Jaipur; SER HQ = Kolkata; East Coast = Bhubaneswar.
- Konkan Railway partners: Maharashtra, Goa, Karnataka (Kerala joined later).
- Atal Tunnel is the longest highway tunnel above 10,000 ft, not in the world overall.
- IRS-1A launched from Baikonur, Kazakhstan, not ‘Russia’.
- NHAI is under MoRTH, not the ‘Ministry of Surface Transport’.
- NW 1 is the Ganga (Haldia–Prayagraj); NW 3 is in Kerala.
- First cross-country pipeline carried crude (OIL), not gas.
How to strategise
Prelims — what UPSC asks
- Roads: old NH numbers (1985 NH 1; 1995 NH 2; 2004 longest route; 2007 NH 6; 2014 NH pairs), transport statements (2002), road vs rail impetus (1994), connectivity projects (2023), Gram Sadak Yojana (2001). Learn the 2010 renumbering too.
- Railways: zones and HQs (2005, 2006), Konkan Railway (1998, 1999), Calcutta metro (1979), Dalhousie (1989), National Rail Plan and Kavach (2025).
- Ports and waterways: Marmagao (1979), riverine port (1998), port map and import tonnage (2000), non-major port (2009), port pairs (2023), Sagarmala (2026). Air: Cochin airport (2005), greenfield airports (2024).
- Satellites: INSAT-1A launch site (1983), first geostationary INSAT-1B (1984), INSAT/PSLV statements (2002), INSAT-3E (2004), IRS uses (2015).
Mains — where it appears and how to answer
- GS1: inland water transport problems and prospects (2016), urban mass transport and growth (2019), IRNSS (2018).
- GS2–GS3: Gati Shakti coordination (GS2 2022), National Urban Transport Policy (2014), airports under PPP (2017), PPP in railway stations (2022), UDAN (2024), electronic toll collection (2024), IRNSS and positioning (2015).
- Answer frame: mode and its strengths → network data (NCERT lengths, shares) → spatial pattern (dense plains, thin hills/NE) → programmes (NHAI corridors, Bharatmala, Konkan, IWAI, Sagarmala, UDAN, gas grid) → issues (congestion, finance, safety, environment) → integration (multimodal, logistics).
- Draw the corridor network, the waterways bars or the Konkan line — schematic, without an outline of India.
Self-check
Tap an option. NCERT's own exercise questions come first; the rest test the figures and common confusions.
1. In how many zones has the Indian Railways system been divided?
2. On which river and between which two places does National Waterway No. 1 lie?
3. In which of the following years was the first radio programme broadcast?
4. The East–West corridor connects:
5. National Highways form about 2 per cent of road length. What share of road traffic do they carry (NCERT)?
6. Which railway zone has its headquarters at Hajipur?
7. Asia's first cross-country pipeline, built by Oil India, ran from:
8. Approximately what share of India's foreign trade by volume moves through ocean routes?
