प्रवासी व माल वाहतुकीचे रेल्वे प्रमुख साधन आहे. सन् 1853 मध्ये मुंबई ते ठाणे हे 34 किमि. चे माफक अंतर कापण्यापासून आता ती सुमारे 64460 किमि. एवढे अंतर कापते या 64460 किमि. रेल्वे अंतरापैकी किती टक्के अंतराचे गेल्या 160 वर्षात विद्युतीकरण झाले आहे ?

The correct answer is Option A (About 30%).

Key Points:
• Core Concept
• Indian Railways represents one of the world's largest rail networks, with continuous capital modernization focused on route electrification.
• Why Correct
• By March 31, 2012 / early 2013 (completing 160 years from April 16, 1853), Indian Railways had electrified approximately 20,000 to 20,800 km of its total ~64,460 to 65,000 km route length.
• Mathematically: (20,000 / 64,460) × 100 ≈ 31%, which corresponds to 'About 30%'.
• Key Details
• Electrified rail tracks carry over 60% of total freight traffic and more than 50% of passenger traffic because trunk routes were prioritized.
• Exam Traps
• Do not evaluate this question using present-day post-2020 statistics (where electrification exceeds 85-90%). In 2013 (marking 160 years of Indian Railways), the cumulative figure was roughly one-third (about 30%).
• Other Options
• Options 2 (40%), 3 (50%), and 4 (60%) greatly exceed the electrified network length achieved by 2012-13.
• Key Takeaway: By 2012-13 (160 years since 1853), about 30% of Indian Railways' route length was electrified.
