When discussing Indian trains, many still cling to the image of overcrowded roofs. However, over the past decade, the Indian railway system has undergone a radical modernization. The latest official figures indicate that the electrification rate of the main railway lines has surpassed 99%, effectively phasing out diesel locomotives. This level not only far exceeds the UK’s electrification rate of less than 40%, but in proportional terms, it is even higher than that of China, challenging many preconceived notions about India’s infrastructural deficiencies.
Is this assertion exaggerated? The answer is no, provided one understands the statistical scope. The cited 99% refers not to scattered branch lines, but to the main network that carries the vast majority of passenger and freight traffic across the country. In other words, India is not merely symbolically promoting electrification; it has completed a nationwide structural transformation, relegating diesel traction to a secondary role.
The key to India’s rapid achievement lies in its highly centralized strategy. The government has clearly defined electrification as a singular national objective, rather than engaging in repeated discussions about the worthiness of each individual route. The engineering process has been highly standardized, with design, equipment, and construction procedures kept consistent, allowing for significant reductions in unit costs and construction timelines due to the large scale of operations. Simultaneous construction alongside ongoing operations has also mitigated the political and economic resistance that long line closures typically generate.
In contrast, progress in the UK appears to be laborious. The issue is not one of technical inadequacy, but rather the weight of historical burdens. Bridges and tunnels from the Victorian era limit clearance, making the later installation of electrical cables complex and costly. Coupled with years of insufficient investment and fluctuating policies, electrification plans have been repeatedly interrupted, leading to escalating costs and ultimately creating a vicious cycle.
The importance of electrification extends beyond environmental image. Electric traction is more efficient, accelerates faster, and can carry heavier trains, which is particularly crucial for high-frequency services and long-distance freight. Maintenance requirements are also lower, allowing for more controllable long-term operational costs. These factors are foundational for railways to leverage economies of scale as a backbone transportation system.
In the context of climate change, the gap continues to widen. Diesel trains, even with ongoing improvements, still emit carbon dioxide and pollutants directly along their routes, with the associated health and environmental costs borne by society as a whole. Electrified railways, on the other hand, concentrate emissions at the power generation stage, and as the grid gradually decarbonizes, the actual carbon footprint of trains will decline over time, representing a long-term resilient transformation pathway.
The experience of Indian Railways offers more than just technical details; it serves as a reminder from a perspective standpoint. Developing countries are not destined to lag behind; when the direction is clear and execution is decisive, the pace of progress often exceeds existing expectations. For the outside world, it may be even more crucial to maintain an open and updated outlook, continuously monitoring the actual advancements in these countries. Sometimes, the speed of change in the world is far quicker than we are accustomed to imagining.
