Chidambaranar (TN) — handles coal, minerals, and containers. (12) Ennore/Kamarajar (Chennai) — India's only corporatized major port (not a trust port); handles coal and LNG. Major Port Authorities Act 2021 replaced the outdated Major Port Trusts Act 1963 — grants ports greater autonomy in pricing and decision-making.
Inland Waterways and Coastal Shipping
India has 14,500 km of navigable waterways, but inland water transport carries less than 2% of freight (compared to 44% in China and 35% in EU). The Inland Waterways Authority of India (IWAI, 1986, HQ Noida) develops and maintains national waterways. 111 National Waterways have been declared under the National Waterways Act 2016, though only a few are operational: NW-1 (Ganga, Prayagraj-Haldia, 1,620 km — the longest and most developed; Jal Marg Vikas Project with World Bank assistance investing Rs 5,369 crore for navigation infrastructure, multi-modal terminals at Varanasi, Sahibganj, and Haldia; vessel capacity of 1,500-2,000 DWT); NW-2 (Brahmaputra, Sadiya-Dhubri, 891 km — important for NE connectivity); NW-3 (West Coast Canal, Kottapuram-Kollam, Kerala, 205 km — the only NW in the south that is operational); NW-4 (Krishna-Godavari rivers and canals in AP and Telangana); NW-5 (Brahmani-Mahanadi delta, Odisha). Advantages of inland waterways: fuel-efficient (1 litre of fuel moves 24 tonne-km by water vs 6 tonne-km by road), low carbon emissions, reduces road congestion, ideal for bulk cargo (coal, sand, food grains). Challenges: seasonal flow variation (rivers are not navigable during dry months), siltation, multiple dams reducing flow, lack of night navigation aids, and poor connectivity to road/rail. Coastal Shipping: India's 7,516.6 km coastline offers huge potential for coastal cargo movement. Sagarmala's coastal shipping initiative aims to shift 200-300 MTPA of cargo from road/rail to coastal shipping by 2025. Ro-Ro (Roll-on Roll-off) ferry services: Ghogha-Hazira Ro-Ro (Gujarat) reduces Mumbai-Saurashtra travel from 10 hours by road to 4 hours by sea. International shipping: India is a member of IMO (International Maritime Organization); Indian National Shipowners' Association represents Indian shipping companies; Shipping Corporation of India (SCI, Navratna PSU) operates India's largest fleet.
Civil Aviation — Growth, Airports, and Air Cargo
India is the world's 3rd largest domestic aviation market (after USA and China) with over 140 million domestic passengers annually (2023). The sector has grown at about 12-15% annually over the past decade. Key regulatory body: DGCA (Directorate General of Civil Aviation) regulates airlines and safety. AAI (Airports Authority of India) manages 137 airports. Major international airports: (1) IGI Airport Delhi (busiest — 72 million passengers/year); (2) CSMIA Mumbai (2nd busiest); (3) Kempegowda Bengaluru (3rd); (4) RGIA Hyderabad; (5) Chennai International; (6) NSC Bose Kolkata; (7) Cochin International (world's first fully solar-powered airport).

(3) Monorail — Mumbai Monorail (19.5 km, India's first); limited expansion due to lower capacity than metro. (4) Light Rail Transit/Tramway — Kolkata Tram (oldest surviving tram in Asia, started 1902) continues limited operations. (5) Electric Vehicles — FAME-II (Faster Adoption and Manufacturing of Electric Vehicles in India, Phase II): Rs 10,000 crore subsidy for EVs including electric buses, two-wheelers, three-wheelers, and four-wheelers; National Electric Mobility Mission Plan targets 30% EV penetration by 2030; major cities deploying electric buses (BEST Mumbai, DTC Delhi, BMTC Bengaluru); charging infrastructure: Ministry targets 46,397 EV charging stations across cities and highways. (6) Non-Motorized Transport — cycling infrastructure in Pune, Chandigarh (Asia's first cycling city by design); pedestrian zones in cities. National Urban Transport Policy (2006, revised 2014) prioritizes: moving people not vehicles, investing in public transport, integrating land use with transport planning, and promoting non-motorized transport. Transit-Oriented Development (TOD) policy encourages high-density mixed-use development around transit stations.
Logistics Infrastructure — National Logistics Policy and PM Gati Shakti
India's logistics cost is about 13-14% of GDP (vs 8% in developed countries), creating a significant competitiveness disadvantage. The National Logistics Policy (2022) aims to reduce logistics cost to 8% of GDP and improve India's Logistics Performance Index (LPI) ranking. Key targets: reduction of logistics cost, improvement of India's LPI ranking from 38th (World Bank 2023) to top 25, creation of a data-driven decision support mechanism, and development of human resources in logistics. PM Gati Shakti National Master Plan (2021) — a GIS-based platform integrating the infrastructure plans of 16 central ministries for coordinated multimodal connectivity planning; identifies gaps in logistics infrastructure and synchronizes project implementation; covers economic zones, industrial areas, rivers, waterways, pipelines, telecom, and all transport modes. Multi-Modal Logistics Parks (MMLPs) — 35 locations identified across India for integrated logistics facilities combining rail, road, and warehousing; Nagpur MMLP (JNPT-linked) is the first to be developed; will consolidate freight movement and reduce empty truck miles. Dedicated Freight Corridors (DFCs) — transformative projects: Eastern DFC (Ludhiana-Dankuni, 1,337 km — passes through Punjab, Haryana, UP, Bihar, Jharkhand, West Bengal) and Western DFC (Dadri-JNPT, 1,504 km — passes through UP, Rajasthan, Gujarat, Maharashtra); designed for double-stack container movement, 25-tonne axle load, and train speeds of 100 km/h; will decongest the existing rail network (currently freight trains average only 25 km/h); estimated to save Rs 14,000 crore annually in logistics costs. National Highways Logistics Management Limited (NHLML) — subsidiary of NHAI — develops wayfarers (highway amenities centres) and logistics parks along NHs. FASTag (mandatory since 2021 for all NHs) has eliminated toll plaza congestion — average transaction time reduced from 714 seconds to 47 seconds; monthly FASTag transactions exceed 30 crore.
Border Roads and Strategic Transport Infrastructure
India's border transport infrastructure has received unprecedented investment since 2014 for strategic connectivity: (1) Border Roads Organisation (BRO, 1960) — builds and maintains roads in border areas of 11 states and 3 UTs; operates in extremely difficult terrain — high-altitude Himalayas, dense forests of NE India, marshy Rann of Kutch; constructs about 10,000 km of roads annually; major projects include: Atal Tunnel/Rohtang Tunnel (9.02 km — world's longest highway tunnel above 10,000 feet, connecting Manali to Lahaul-Spiti, inaugurated 2020); Zoji La Tunnel (14.2 km — under construction, will provide all-weather connectivity between Srinagar and Leh); Sela Tunnel (Arunachal Pradesh — 13.6 km, provides all-weather connectivity to Tawang); Col. Chewang Rinchen Bridge at Shyok, Ladakh (highest altitude bridge); Daulat Beg Oldi road (connects Leh to the world's highest airstrip at DBO in Ladakh near the LAC).
