These roads and railways notes for OPSC/UPSC (Part I of transport) cover the road network, national highway programmes, railway history, gauges, zones, production units and major lines, with prelims facts, mains analysis and the Odisha angle. Prelims asks mostly corridor end points, zone headquarters and “firsts”, while mains uses the same material for logistics, regional development and safety answers. Air transport, waterways, ports and pipelines are in Part II.
Roads and Railways Notes for OPSC/UPSC: Transport Basics
The process of carrying people or goods from one place to another by overcoming the friction of distance.
| Mode | Strength | Limit |
|---|---|---|
| Roadways | Door-to-door, flexible, best for short and medium distances | Costly for bulk over long distances; congestion and accidents |
| Railways | Efficient for bulk and long-distance freight and mass passenger travel | Fixed routes, needs terminals |
| Waterways | Cheapest per tonne-km for bulk cargo | Slow, depends on rivers and ports |
| Airways | Fastest; reaches remote and hilly areas | Costly, low volume |
- India has the second largest road network in the world, about 63 lakh km, and the fourth largest railway network after the USA, China and Russia. Roads carry about two-thirds of freight and most passengers.
- Waterways are the most efficient form of transport over long distances for bulk goods. Civil aviation is among the fastest growing sectors.
- Indian Railways is the fourth largest network, not the third.
- Roads, not railways, carry most passenger traffic in India.
Road Transport in India: Classification and National Highways
Classification of roads
| Class | Built and maintained by | Remark |
|---|---|---|
| National Highways | Central government (NHAI, MoRTH, BRO, state PWDs) | About 2% of road length but about 40% of road traffic BPSC 2008 |
| State Highways | State PWDs | Link state capitals, district headquarters and NHs |
| District roads | Zila parishads and PWDs | Link production areas to markets and highways |
| Rural roads | Panchayats, PMGSY agencies | Largest share of total length |
| Border roads | Border Roads Organisation | Strategic roads in border and hilly areas |
| Expressways | NHAI, states | Access-controlled, fast corridors |
- National highway length has grown from about 91,000 km in 2014 to about 1.46 lakh km in recent years.
- NH 44 (Srinagar to Kanyakumari, about 3,700 km) is the longest national highway. NH 966 B at Kochi is among the shortest.
- National highways were renumbered in 2010, so questions that quote a number should say which numbering applies.
NHAI and the highway programmes
- NHAI: set up by the National Highways Authority of India Act, 1988 and operational from 1995, under the Ministry of Road Transport and Highways. It builds and maintains the highways entrusted to it.
- National Highways Development Project (NHDP): started in the late 1990s and is the first big programme. Phase I built the Golden Quadrilateral and the North-South and East-West corridors.
- Bharatmala Pariyojana: approved in 2017 as an umbrella programme for economic corridors, inter-corridors and feeder routes, border and international connectivity roads, coastal and port connectivity roads, expressways, and completion of the remaining NHDP work. CDS 2008
| Corridor | Route and length |
|---|---|
| Golden Quadrilateral | Delhi, Mumbai, Chennai, Kolkata, about 5,800 km MPPSC 2016 |
| North-South Corridor | Srinagar to Kanyakumari, about 4,000 km, passing through Agra, Gwalior, Nagpur, Hyderabad and Krishnagiri RAS/RTS 2016 |
| East-West Corridor | Silchar to Porbandar, about 3,300 km MPPSC 2019 |
The North-South and East-West corridors intersect at Jhansi in Uttar Pradesh. CDS 2008 The Golden Quadrilateral joins Delhi, Mumbai, Chennai and Kolkata; Bengaluru is not one of its nodes.

Rural and border roads and tunnels
- PMGSY: launched in December 2000 under the Ministry of Rural Development to give all-weather connectivity to unconnected rural habitations, implemented through state agencies. UPPSC 2001
- Border Roads Organisation: formed in 1960 under the Ministry of Defence. It built the Atal Tunnel (about 9 km, opened in 2020) under Rohtang, which gives all-weather access from Manali to Lahaul-Spiti.
- Jawahar Tunnel: crosses the Banihal pass on the Jammu-Srinagar route. CGPSC 2014 Zojila is the pass on the Srinagar-Leh road.

Konkan Railway, Heritage Railways and Modern Trains
- Konkan Railway: runs from Roha (Maharashtra) to Mangalore (Karnataka), about 740 km, through Maharashtra, Goa and Karnataka. SSC 2011 It was built by Konkan Railway Corporation Limited (formed 1990, HQ Navi Mumbai), opened in 1998, and raised funds through bonds. E. Sreedharan led the project. RRB 2001
- Mountain railways: Darjeeling Himalayan Railway (UNESCO World Heritage Site 1999), Nilgiri Mountain Railway (added 2005) and Kalka-Shimla Railway (added 2008). RAS/RTS 2013
- Luxury and heritage trains: Deccan Odyssey, a luxury train through Maharashtra and Goa UPSC 2004; Palace on Wheels; Maharajas’ Express; Fairy Queen, which uses the oldest working steam locomotive.
- Modern services: Vande Bharat (indigenous, built at ICF), Tejas (the first IRCTC-operated train, 2019), Kisan Rail (first run in August 2020 from Devlali to Danapur) and the Mumbai-Ahmedabad bullet train being built with Japanese help.
- Others: India’s first CNG train ran on the Rewari-Rohtak section. UPPSC Mains 2016 The Pir Panjal tunnel (about 11 km) is the longest rail tunnel in India.
Coal is the largest commodity carried by Indian Railways, followed by iron ore, cement and foodgrains. This is why mineral-rich Odisha, Jharkhand and Chhattisgarh generate so much rail freight.
Dedicated Freight Corridors
| Corridor | Route |
|---|---|
| Eastern DFC | Ludhiana (Punjab) to Dankuni (West Bengal) |
| Western DFC | Jawaharlal Nehru Port (Navi Mumbai) to Dadri (Uttar Pradesh) |
Both are built by the Dedicated Freight Corridor Corporation of India Limited, to separate freight from passenger trains and increase speed and capacity.
Transport in Odisha: Roads, Railways and Mains Link
- Highways: Odisha lies on the Kolkata-Chennai arm of the Golden Quadrilateral (NH 16), which enters from West Bengal near Balasore and passes Cuttack, Bhubaneswar and Berhampur before entering Andhra Pradesh. The Delhi-Mumbai arm does not touch the state.
- Railways: the East Coast Railway, headquartered at Bhubaneswar, has divisions including Khurda Road and Sambalpur. Rourkela is served by the South Eastern Railway. Vande Bharat services reach Odisha, for example Puri-Howrah (2023).
- Freight: Odisha’s coal from the Talcher and Ib valley fields and its iron ore make it one of the busiest freight origins. Port connectivity roads and rail links to Paradip and Dhamra are part of Bharatmala and port-led development.
- Safety: the Balasore (Bahanaga Bazar) train collision of June 2023 was one of India’s worst railway accidents and brought attention to signalling and the Kavach anti-collision system.
A tonne of iron ore from Keonjhar reaches Paradip by the rail network of the East Coast and South Eastern Railways and then moves by sea. The rail-port chain shows how transport links Odisha’s mineral belt to the coast.
Mains Analysis: Roads, Railways and Logistics
- Modal mix: the share of rail in freight has fallen while roads now carry about two-thirds. This raises fuel use, emissions and logistics costs, so a shift to rail and waterways is a policy aim.
- Policy frame: PM Gati Shakti National Master Plan (October 2021) for integrated infrastructure planning, the National Logistics Policy (2022), Bharatmala, DFCs and Sagarmala work together on multimodal logistics.
- Regional development: corridors and PMGSY roads open markets, healthcare and schools to remote and tribal areas, and border roads help defence and integration of the North-East.
- Challenges: land acquisition, delays and cost overruns, road safety, toll and financing issues, railway safety and finances, and environmental clearance in sensitive areas such as the Himalayas.
- Railway reforms: the merger of the railway budget with the Union Budget (2017), private operation of some trains, Kavach, electrification and station redevelopment are recurring themes.
- Environment: electrification, dedicated freight corridors and modal shift reduce emissions, while road building in the hills raises landslide and ecology concerns.
Prelims loves corridor end points, zone headquarters and “first” facts; mains asks for balanced evaluation of a scheme. Learn each programme as: year, agency, aim, one example and one limitation.
