Indian Railways is set to receive 300 new high-power diesel locomotives from US-based Wabtec by the financial year 2028. This delivery is part of a $2.5 billion public-private partnership, even as the national transporter aims for near 100 per cent electrification and plans to phase out all diesel engines from its main network.Under the 'Make in India' programme, Wabtec's plant in Marhowra, Bihar, is contracted to supply a total of 1,000 fuel-efficient, emission-compliant diesel-electric Evolution Series locomotives. The facility, which commenced operations in 2018, has already delivered 700 units.Although these 4,500 HP and 6,000 HP locomotives were primarily intended for freight movement, all trains on the dedicated East and West freight corridors are now hauled by electric locomotives. The new diesel engines, with a lifespan of 35 years, will form part of the railways' 2,500-strong emergency fleet, reserved for disaster response and strategic requirements.Despite concerns regarding the future of the Marhowra factory as diesel operations wind down, Wabtec has plans to maintain its functionality. Sujatha Narayan, Senior Vice President and India Region Leader from Wabtec, stated that the contract for the remaining 300 locomotives stands. For future operations, the company will focus on local domestic opportunities with Indian Railways, exports, and railway components to utilise the substantial infrastructure built.Wabtec is also expanding its export portfolio, with the first two of 70 locomotives ordered by Rio Tinto for Africa's Simandou iron ore project set to sail in June this year. The company has a total export order of 140 locomotives. These advanced engines feature AC cabins for loco pilots, toilets, refrigerators, engine trail systems, and smart electronics, making them suitable for heavy haulage, including on hilly terrain.Image source:railway.supply
