SSC CGL Geography · Indian Geography — Economy, Resources and Transport

Transport and Ports

India's roads, highway corridors and tunnels, its railways and national waterways, and its ports on the two coasts.

Why this matters

Twenty-seven questions in the bank: 13 from the 2023 shifts, 12 from the 2024 shifts and two from the 2025 shifts. They ask a first, a largest or an endpoint: the first train, the corridors' end cities, the satellite port of Mumbai. A list of firsts and endpoints is the page.

Concept 1 of 3: Roads, corridors and tunnels

Roads carry most of India's people. SSC asks who builds the national highways, where the two great corridors run, which tunnel is newest, and which States have dense or thin road networks.

Definition

The facts:

  • India has the world's second largest road network, after the USA. Roads carry about 87% of passenger traffic.
  • NHAI (National Highways Authority of India) builds and maintains the national highways. It was set up by an Act of 1988 and began work in 1995.
  • North-South corridor: Srinagar to Kanyakumari. East-West corridor: Silchar to Porbandar. They cross at Jhansi.
  • Atal Tunnel (2020), under the Pir Panjal range near Rohtang at about 3,000 m, is the longest single-tube highway tunnel at that height; it shortens the Manali to Keylong road.
  • Road density depends on terrain and economic development: it is highest in Kerala and low in the hilly North-East.

Example 1 · Indian Geography — Economy, Resources and Transport · Transport and Ports

Which of the following statements is/are INCORRECT regarding the density of roads in India? A. Level of economic development and terrain are the determinants of road density in a region. B. Road density is higher in the North-Eastern states than in the Southern states of India. C. Road density of Kerala is higher than the average national road density.

The North-East has low road density

Road density is high in the south and low in the hilly North-East. A statement reversing them is false.

Concept 2 of 3: Railways, waterways and airports

India's railways began with a short line out of Bombay, and the plains now hold most of the track. Waterways are numbered, and SSC asks which number is which river.

Definition

Railways:

  • The first train ran on 16 April 1853 from Bombay to Thane (about 34 km).
  • The route length was 67,956 km in 2020. Broad gauge covers most of it.
  • Uttar Pradesh has the longest network of any State; hilly Sikkim has almost none.
  • Eastern Railway (Kolkata) has the Howrah, Sealdah, Asansol and Malda divisions.

Waterways:

  • The National Waterways Act, 2016 declared 111 national waterways.
  • NW 1: the Ganga. NW 2: the Brahmaputra. NW 3: the West Coast Canal. NW 5: the East Coast Canal with the Brahmani and Mahanadi delta.
  • The India-Bangladesh Protocol route links NW 1 in the mainland with NW 2 in the North-East.

Airports: Mizoram has just one operational airport (Lengpui).

Example 2 · Indian Geography — Economy, Resources and Transport · Transport and Ports

Consider the following statements regarding the development of railways in India. 1. The first railway line was started in 1853 from Bombay to Pune. 2. The broad gauge covers the highest proportion of tracks of Indian railways. Which of the statement(s) given is/are INCORRECT?

Thane, not Pune

The first train of 1853 ran from Bombay to Thane. Pune, Karjat and Palghar are decoys.

Concept 3 of 3: Ports on the two coasts

Port questions ask which coast a port is on, which port is the biggest for containers, and which was built to take the load off an older one.

Definition

The facts:

  • West coast: Kandla (Deendayal), Mumbai, Jawaharlal Nehru (Nhava Sheva), Mormugao, New Mangalore, Kochi.
  • East coast: Kolkata with Haldia, Paradip, Visakhapatnam, Chennai, Tuticorin.
  • Jawaharlal Nehru Port is India's largest container port, built as a satellite port to relieve Mumbai. Haldia was built as a subsidiary port to Kolkata.
  • About 95% of India's foreign trade by volume goes by sea, and most of the rest by air.

Example 3 · Indian Geography — Economy, Resources and Transport · Transport and Ports

Which port is developed as a satellite port?

Haldia is on the east coast

In a 'NOT on the west coast' question, Haldia (on the Hooghly) is the answer. Kandla, Mangaluru and Mormugao are all west coast ports.
