This is a straightforward geographical/factual question about India's railways. The answer requires knowledge of major railway routes and their lengths.
Step 1: Understand what the question asks
The question seeks the longest railway line in India. We need to distinguish between a train route and railway administrative zones.
Step 2: Analyze the options
- (A) Dibrugarh–Kanyakumari Vivek Express: This is a train service (not a railway line itself), but it operates on the longest railway route in India, spanning approximately 4,233 km from Assam (northeast) to Kerala (southwest).
- (B) South Western Railway: This is a railway zone/administrative division, not a specific line.
- (C) Central Railway: This is also a railway zone, not a specific line.
- (D) Northern Railway: This is a railway zone, not a specific line.
Step 3: Identify the actual longest route
The Dibrugarh–Kanyakumari route is the longest continuous railway route in India, connecting the northeastern region to the southern tip of the country. This train service covers the maximum distance among all Indian railway routes.
Step 4: Eliminate confusion
Options B, C, and D refer to railway zones (administrative regions), not actual railway lines or routes. The question specifically asks for the longest "railway line," which refers to a specific route.
Answer: The Dibrugarh–Kanyakumari Vivek Express route is the longest railway line in India at approximately 4,233 km. (Option A)
As of 2024, India has 18 railway zones after the creation of new zones in recent years.
