How Has 100 Years of Electrification Transformed Indian Railways? A Milestone Worth Celebrating
On February 3, 2025, Indian Railways celebrates a century of electric traction. But how has this transformation reshaped one of the world’s largest rail networks? And what lies ahead as India inches closer to complete electrification? With over 95% of its broad-gauge network electrified, India is on the brink of achieving 100% electrification, a feat that could have profound implications for the nation's economy, environment, and efficiency.
A Century of Change: The First Electric Train Journey
It all began on February 3, 1925, when India witnessed its first electric-powered train journey between Chhatrapati Shivaji Maharaj Terminus (CST) and Kurla in Mumbai, covering a modest distance of 16 km. Powered by 1,500 Volts of Direct Current (DC), this marked the beginning of a transformation that would take nearly a century to complete. While Werner von Siemens had demonstrated the world’s first electric train in 1879, India became the 24th country globally and the third in Asia to adopt electric railways.
The Journey to Full Electrification: Key Milestones
From its humble beginnings, India's electrification journey has been nothing short of spectacular. By 1951, the electrified network had expanded to 388 km, and by 1966, more than half of the freight traffic in the Eastern and South Eastern Railway zones was powered by electricity. The real acceleration came after 2014-15, when Indian Railways significantly ramped up its electrification efforts. From about 1.42 km per day in the previous decade, the pace surged to an impressive 19.7 km per day in 2023-24, marking an ambitious leap forward in rail infrastructure development.
By November 2024, India had electrified a 45,200-route km network, and the country is now poised to complete electrification of its broad gauge network by fiscal 2026. As the Southern Railway (SR) zone nears 96% electrification across its 5,093 route km, the promise of cleaner, more efficient transport is becoming increasingly evident.
The Economic and Environmental Benefits
Electrification has proven to be a game-changer in multiple ways. From an economic standpoint, the cost-efficiency of electric traction is undeniable. The line haul cost per 1,000 Gross Tonne Kilometres (GTKM) for electric traction in passenger services is ?123.5, compared to ?213 for diesel traction—a ?89.5 savings per 1,000 GTKM. This difference in cost is even more pronounced in freight services, where diesel traction costs 3.05 times more than its electric counterpart.
Beyond financial savings, the environmental impact of electrification cannot be overstated. Electric trains are more efficient, reduce diesel dependency, and have a lower carbon footprint. However, full environmental benefits will be realized only when India's electric grid shifts significantly toward renewable energy sources. Currently, 75% of electricity in India is sourced from fossil fuels, primarily coal, which tempers the full environmental impact of electrification.

The Road Ahead: India’s Mission 100% Electrification
India’s electrification efforts align with the country’s broader mission of transitioning to cleaner energy and improving transportation efficiency. As the Indian government pushes towards 100% electrification of the broad gauge network by 2026, the focus will shift to ensuring a seamless transition from diesel to electric traction, minimizing disruptions, and enhancing speed and efficiency. Notably, electric-powered trains offer higher speeds, heavier trailing loads, and the ability to run longer distances without needing fuel stops.
This significant milestone is not just about reduced operational costs; it is also a step toward energy security by reducing reliance on imported crude. For instance, freight services benefit from higher load capacity and faster turnaround times, translating to a more efficient freight network, crucial for India’s vast supply chains.
Key Takeaways
In conclusion, India's electrification of its railways over the past 100 years is not just an engineering achievement; it is a strategic step towards more sustainable, cost-effective, and efficient transportation. With full electrification on the horizon, Indian Railways is poised to lead the charge into a cleaner and more efficient future, benefiting both the economy and the environment. The journey from 16 km to nearly 45,200 route km of electrified tracks has set the stage for the next phase in India's rail revolution.
