The correct option is Creating a direct coastal rail link across Maharashtra, Goa and Karnataka.
Explanation
The Konkan Railway is a landmark infrastructure project in India designed to bridge the gap in the railway network along the rugged Western Coast. It traverses the challenging terrain of the Western Ghats, necessitating the construction of numerous tunnels and bridges to maintain connectivity.
Option Analysis:
- Creating a direct coastal rail link across Maharashtra, Goa and Karnataka is Correct: The Konkan Railway establishes a direct link between Roha in Maharashtra and Thokur (near Mangalore) in Karnataka, passing through Goa. Prior to its completion, rail travel between Mumbai and Mangalore required a circuitous inland route. This coastal corridor significantly reduced travel distance and time.
- Eliminating rail congestion in the Thar Desert through an alternate corridor is Incorrect: The Thar Desert is located in northwestern India (Rajasthan), whereas the Konkan Railway operates along the southwestern coast. There is no geographical connection between the Konkan line and congestion relief in the Thar Desert.
- Providing the first high-speed railway service in India is Incorrect: The Konkan Railway is a conventional broad-gauge railway line. It is not classified as a "high-speed railway" (HSR) system, a category reserved for projects like the Mumbai-Ahmedabad Bullet Train corridor.
- Facilitating the movement of petroleum exclusively is Incorrect: The line is a multi-purpose corridor facilitating both passenger and freight movement. It transports diverse commodities such as food grains, cement, and fertilizers, and is not restricted exclusively to petroleum.
Key Takeaway: The Konkan Railway (approximately 760 km) connects the states of Maharashtra, Goa, and Karnataka along the Western Ghats, providing a critical direct rail link between Mumbai and Mangalore.
