From the Arthashastra to colonial railways to state-led public investment
Infrastructure: Transport, Communications and Energy · section 2 of 10
In this note
Detail
1. The ancient layer: Kautilya's Arthashastra
- Infrastructure means the basic physical facilities an economy runs on: roads, railways, ports, power, water and communication. India has thought about it for a very long time.
- Three bodies shared the work. The state, the grāma (village) and the sabhās (local assemblies) all built and repaired roads and waterways.
-
So road-building was a shared public duty. It was not left to private persons.
-
Roads were sized to their traffic. The janapadas (territorial states or regions) had to build roads of different widths, depending on how busy the road would be:
| Road type | Width (converted) | Why this width |
|---|---|---|
| Royal highways; roads in the countryside, to port towns and to villages | ~16 m | Heaviest traffic: trade, the army, goods going to ports |
| Forest roads; roads within the city | ~8 m | Medium traffic |
| Chariot roads | ~2.5 m | A single vehicle |
- Penalties protected public assets:
- breaking a reservoir dam brought a severe penalty, because water storage fed farming;
- breaking a hedge to trespass into a public park brought a fine;
-
blocking paths to waterworks and forests brought a fine.
-
Lesson for today. Building an asset is only half the job. The other half is maintenance, and deterrence (penalties that stop people from damaging it). Modern laws that punish damage to public property follow the same idea.
2. The colonial layer: built for the empire, not for the people (Class 11, §1.8)
- What was built: railways, ports, water transport, posts and telegraphs.
- Why it was built: NCERT says the real motive was "to subserve various colonial interests" (to serve the needs of the colonial power). Providing amenities to Indians was not the aim.
2a. Roads
- Purpose: roads were built to:
- move the army;
-
carry raw materials from the countryside to the nearest railway station or port, from where they were shipped to Britain.
-
What was missing: all-weather rural roads, meaning roads that stay usable in the rains (paved or metalled, with drainage).
- Villages were cut off in the monsoon → food and relief could not reach them → villagers suffered badly during natural calamities and famines.
2b. Railways
- Start date. The first passenger train ran from Bori Bunder (Bombay) to Thane on 16 April 1853. It covered about 34–35 km [9].
- It had about 400 passengers in 14 carriages. The Great Indian Peninsula Railway (GIPR) ran it. A 21-gun salute marked the start, and Bombay declared a public holiday [9].
-
NCERT error: Class 11 says railways came "in 1850". The correct year is 1853, as Class 7 says. The Thane creek bridge (Class 11, Fig. 1.4) came in 1854.
-
Three colonial motives (Class 7):
- carry cotton and tea to ports for export to Britain;
- open an Indian market for British factory goods;
-
move troops quickly and tighten political control.
-
Class 7, Fig. 7.7, maps the rail network as it stood in 1882.
- Two-sided effect:
- Positive. Long-distance travel became possible. This broke geographical and cultural barriers between regions.
- Negative, as a chain:
- railways speeded up the commercialisation of agriculture (farmers grew crops for sale and export, not for their own food);
- this eroded village self-sufficiency (villages could no longer meet their own needs);
- exports grew, but the gains went to Britain.
- NCERT's verdict: the social benefits were "outweighed by the country's huge economic loss".
2c. The Orissa Coast Canal: a case study in bad planning
- The canal was built at huge cost to the exchequer (the government treasury).
- Then a railway was laid parallel to it.
-
The railway was faster → traffic shifted away from the canal → the canal could not compete → it was abandoned.
-
Lesson: this is a classic case of badly coordinated modal planning. (A "mode" is one type of transport: road, rail, water or air. Modal planning means deciding which mode serves which route.) Two modes competed for the same route, and public money was wasted. The modern answer is integrated multimodal planning, such as PM Gati Shakti (see §3d).
2d. Communications and aviation
- Electric telegraph. It was an expensive system. Its main use was keeping law and order for the colonial state.
- Posts. They were useful to the public but "remained all through inadequate".
- Aviation. Tata Airlines, a division of Tata Sons, began Indian aviation in 1932 (Class 11, Fig. 1.5).
- The Suez Canal (1869) made the trip between India and Britain much shorter. It is covered in the colonial-economy-1947 note.
2e. The 1947 verdict (Class 11, §1.9)
- At Independence, infrastructure, "including the famed railway network, needed upgradation, expansion and public orientation".
- Upgradation: old assets had to be modernised.
- Expansion: coverage was thin, especially in rural areas.
- Public orientation: assets had to be redesigned to serve Indians, not exports and troops.
3. The modern layer: state-led build-out → PPPs → the public capex push
3a. Why the state had to provide infrastructure (Class 10, Sectors of the Indian Economy)
- Huge sums. Roads, bridges, railways, harbours, electricity and irrigation dams need money far beyond what private firms can put up.
- Hard to collect user charges. A user charge is a fee paid by the person who uses a service, such as a toll or a water fee. Collecting it from thousands of users is costly and difficult.
- Affordability. Private providers would charge high rates, and many people could not pay.
- Subsidy logic. Cheap (subsidised) power for small industrial units follows the same reasoning. The state gives up some revenue so that small firms and jobs can survive.
- Public investment in infrastructure means heavy government spending on assets that the private sector will not supply at a reasonable cost.
3b. The planning era (1951 onwards)
- The state held the commanding heights of the economy: the key, strategic sectors such as power and irrigation. Details are in the planning-mixed-economy note.
3c. After 1991: private capital enters
- Private money was invited in through Public–Private Partnerships (PPPs). In a PPP, a private firm builds and/or runs a public asset under a long contract with the government. See sections 9–10 of this topic.
3d. Since 2020: the public-capex push
- Capital expenditure (capex) is government spending that creates long-lasting assets (roads, rail lines, ports) or reduces debts. It is different from revenue expenditure, such as salaries, interest and subsidies, which creates no asset.
- National Infrastructure Pipeline (NIP). About ₹111 lakh crore of projects were planned over FY20–FY25 (NIP Task Force, 2020).
- PM Gati Shakti National Master Plan (NMP). It was launched on 13 October 2021 [5].
- It is a digital platform that brings 16 Ministries, including Railways and Road Transport, together for integrated planning of connectivity projects [5].
- It covers schemes such as Bharatmala (roads), Sagarmala (ports), inland waterways, dry/land ports and UDAN (regional air connectivity) [5].
- Its Network Planning Group had evaluated 352 infrastructure projects worth ₹16.10 lakh crore by 2026 [6].
-
This is the direct fix for the Orissa-canal type of failure: it plans all modes together instead of letting them compete.
-
Union capex has grown fast:
| Year | Union capex | Source |
|---|---|---|
| FY2014-15 | ~₹2 lakh crore | [2] |
| FY2017-18 | ₹2.63 lakh crore | [3] |
| 2024-25 BE | ~₹11.1 lakh crore | NCERT scaffold |
| 2025-26 BE | ₹11.21 lakh crore (about 4.2 times FY18) | [3] |
| 2026-27 BE | ₹12.2 lakh crore, about 11.5% above 2025-26 RE | [2][4] |
- Effective capital expenditure. This is the Union's own capex plus the grants-in-aid it gives states for creating capital assets. It measures the full asset-building push, including assets that states build with central money.
- Formula: Effective capex = Union capital expenditure + Grants-in-aid for creation of capital assets
-
Worked example (2025-26 BE): effective capex was ₹15.48 lakh crore [3] (NCERT: ~₹15.5 lakh crore), and capex was ₹11.21 lakh crore. So grants for capital assets = 15.48 − 11.21 = ₹4.27 lakh crore.
-
The capex multiplier. The multiplier is the increase in GDP produced by each extra ₹1 of spending: Multiplier = ΔGDP ÷ ΔSpending.
- Illustrative example: if an extra ₹1 lakh crore of capex raises GDP by ₹2.5 lakh crore, the multiplier is 2.5 ÷ 1 = 2.5.
-
Capex has a higher multiplier than revenue spending. It creates jobs now (building) and more output later (the asset keeps working). This is the stated reason for the SASCI scheme [7].
-
SASCI (Special Assistance to States for Capital Investment). The Centre gives states 50-year interest-free loans that must be spent on capex [7].
- The loans grew from about ₹12,000 crore (2020-21) to ₹1.5 lakh crore (2025-26 BE) [7][8].
- States are estimated to fund 19% of their capital outlay through SASCI loans in 2024-25, up from 2.9% in 2020-21 [7].
-
Part of the money is tied to reforms by states (incentives for reforms) [8].
-
New in Budget 2026-27:
- an Infrastructure Risk Guarantee Fund, to reassure private developers about risks during construction [2];
- a focus on cities with more than 5 lakh population as new growth centres, with investment in housing, transport and urban infrastructure [2].
- The fund signals the next step: the state keeps spending, but it also takes on part of the risk so that private capital comes back in.
Prelims Hooks
- First passenger train: Bori Bunder–Thane, 16 April 1853, run by the GIPR, about 34 km [9]. The Class 11 figure of "1850" is wrong. The Thane creek bridge came in 1854.
- Arthashastra road widths: royal highways and roads to ports and villages ~16 m; forest and city roads ~8 m; chariot roads ~2.5 m. Road-builders: the state, grāma and sabhās.
- Orissa Coast Canal: abandoned because a parallel railway took its traffic. It is the textbook example of poor modal coordination.
- Indian aviation began in 1932 with Tata Airlines, a division of Tata Sons.
- PM Gati Shakti NMP: launched 13 October 2021; a digital platform linking 16 Ministries [5]. Trap: it is a planning platform, not a funding scheme.
- NIP: about ₹111 lakh crore of projects over FY20–FY25.
- Effective capex = Union capex + grants-in-aid for creation of capital assets. It was ₹15.48 lakh crore in 2025-26 BE [3].
- Union capex 2026-27 BE: ₹12.2 lakh crore [2].
- SASCI: 50-year interest-free loans to states for capex. They were ₹1.5 lakh crore in 2025-26 BE [8]. Trap: they are loans, not grants.
Mains Points
- Motive decides design. Colonial railways and roads linked ports to raw-material areas but left villages without all-weather roads. So network size alone is not development: in 1947 NCERT asked for "public orientation". Rural roads and last-mile connectivity carry the equity side of infrastructure policy (GS-III).
- Why the state leads, and its limits. The Class 10 logic is huge sums, hard user-charge collection and the need for affordability. This justifies public capex, which has risen from ~₹2 lakh crore (FY15) to ₹12.2 lakh crore (2026-27 BE) [2]. Public borrowing has limits, however. So the state is shifting toward crowding in private money through PPPs and risk-sharing tools such as the Infrastructure Risk Guarantee Fund [2].
- Coordination beats competition between modes. The Orissa Coast Canal shows how parallel investment wastes public money. PM Gati Shakti's integrated, multi-ministry GIS planning [5][6] is the institutional answer. Use this pairing in logistics-cost and multimodal-transport answers.
- Fiscal federalism through capex. SASCI [7] pushes states to build assets and to reform. But it also raises questions of state autonomy (conditional money) and dependence (19% of state capital outlay in 2024-25). This links GS-III (investment) with GS-II (Centre–state relations).
