Bhubaneswar, Nov 13: The East Coast Railway (ECoR) is set to enhance its electrification capabilities with the introduction of the 2×25 KV Overhead Electrification (OHE) system on several key railway routes within its jurisdiction, officials confirmed on Tuesday.
The upgrade is aimed at improving voltage stability, ensuring smoother operations for semi-high-speed trains, and increasing the capacity for transporting heavy goods. To meet the Railway Board’s goal of handling 3000 MT loading capacity and support the operation of high-speed trains, the existing 1×25 KV system will be replaced with the more robust 2×25 KV OHE system.
This new system will improve the power distribution along railway lines, with voltage levels raised to 50 KV, while providing the necessary 25 KV power to trains. The power will be supplied from Traction Sub-stations (TSS) using 50 KV transformers, with intermediate autotransformers ensuring that the 25 KV is delivered to the trains.
The upgraded infrastructure will not only ensure better voltage regulation but also meet the growing demand for traction power, ensuring smoother and more efficient operations for both passenger and freight trains across the network. This development is a major step toward enhancing the overall efficiency and capacity of ECoR’s railway services.
