The Double-Edged Sword of Scale
Indian Railways (IR) has reached a significant milestone, becoming the world's second-largest rail cargo carrier by volume. It moved approximately 1.6 billion metric tonnes (BMT) in fiscal year 2024-25. This impressive figure places it behind China (approx. 4.0 BMT) but ahead of the United States (approx. 1.5 BMT) and Russia. This ascent is largely credited to the near-complete rollout of the Dedicated Freight Corridors (DFCs), a network spanning over 2,800 km, which now handles around 300-325 trains daily. While the DFCs have significantly boosted freight volume capacity, operational data shows a less robust picture for revenue generation. Originating freight traffic grew by only 3 percent since the DFCs were declared "near complete" nearly two years ago. Throughput measured in Net Tonne Kilometres (NTKM)—a better indicator of revenue—initially grew by less than 1 percent. Although recent data for February 2026 indicates NTKM growth at 4.18%, and FY25-26 saw a 3.25% increase in total freight volume to 1,670 million tonnes, overall revenue growth for FY25-26 barely kept pace with volume increases. Freight earnings for FY25-26 reached approximately ₹1.77 lakh crore, a modest 1.44% rise from the previous year, falling short of earlier projections and trailing the volume expansion rate. This suggests revenue per tonne-kilometer may be declining, or operating costs are rising faster than anticipated.
Financial Strain and Electrification Paradox
The financial health of Indian Railways is a constant concern. Despite record capital expenditure and infrastructure expansion, the organization faces significant sustainability challenges, marked by a difficult operating ratio. The salary and pension bill alone accounts for over 64 percent of total revenues. Furthermore, the profitable freight segment is increasingly tasked with subsidizing the loss-making passenger services, which incur annual losses of around ₹68,269 crore. This reliance on freight revenue for cross-subsidization adds pressure to freight pricing and margins. The ambitious electrification drive, nearing 100 percent completion for the broad-gauge network, has been praised for saving ₹6,000 crore in annual fuel costs. This shift from diesel aims to reduce reliance on imported fossil fuels, which previously formed a large part of the annual energy bill, estimated at ₹18,000-₹20,000 crore for diesel alone. However, the strategic advantage of electrification is questioned by the return on investment. Around 5,000 diesel locomotives, valued at about ₹30,000 crore, raise concerns about asset underutilization. Moreover, the 'green' credentials of this massive shift are debatable when over half of India's electricity is still generated from coal. With coal-fired power generation making up roughly 70% of the electricity mix, the environmental benefits of electrifying rail are diminished if the power source itself is carbon-intensive.
The Bear Case: Underutilized Assets and Diminishing Returns
Several factors contribute to a cautious outlook for Indian Railways. While volume has increased, the growth in NTKM, a more revenue-indicative metric, has been less dynamic, particularly in the periods following DFC completion. This difference could indicate challenges in freight mix, fewer longer hauls than expected, or competitive pressures impacting revenue. Historically, past electrification projects faced issues. For example, one World Bank-supported project in the 1980s yielded a mere 7% return against a projected 25%, partly due to oil price drops and problems importing high-efficiency electric locomotives. The reliance on freight revenue to cover passenger losses creates a structural weakness. Any slowdown in freight demand, increased competition from road transport, or rising operational costs could severely impact overall financial sustainability. The railways' share of freight transport, though growing, still lags behind other modes in certain sectors. The significant value tied up in underutilized diesel locomotives represents capital inefficiency that may affect future returns. This dependency means the full 'green' impact of widespread electrification is uncertain. Environmental savings may be less significant than initially stated if the grid's coal reliance persists.
Future Outlook: Navigating Growth and Efficiency
Looking ahead, Indian Railways aims to further boost freight volumes, targeting 1,702 MT for FY25-26 and projecting 1,765 MT by FY2027. Achieving these targets while improving financial performance will be crucial. The organization's ability to diversify its freight portfolio beyond traditional bulk commodities and increase revenue per tonne-kilometer will be key. Analysts note that revenue growth has lagged volume growth recently, indicating a need for better operational efficiency and possibly adjusted tariff structures, although passenger fares remain politically sensitive. Continued investment in infrastructure, alongside a strategic focus on cost management and revenue generation, will be essential to balance ambitious volume targets with financial prudence.
