Mumbai-Ahmedabad bullet train project latest update

The installation of Overhead Electrification (OHE) masts along the Mumbai–Ahmedabad bullet train corridor marks an important step towards electric traction for India’s first high-speed rail system. The OHE masts installation is underway across key sections of the alignment, including viaduct stretches.

It will support safe, smooth and efficient high-speed train operations. According to railways, these masts form a critical part of the traction infrastructure required for reliable power supply to bullet trains running on the corridor.

What is OHE masts?

The OHE masts are vertical steel structures installed alongside railway tracks that support overhead electric wires. They maintain the correct height, alignment and tension of the wires, enabling continuous and safe power supply to electric trains.

Mumbai-Ahmedabad bullet train corridor: OHE masts installation

The OHE masts are being installed on elevated viaducts at significant heights above ground level. A total of more than 20,000 masts, ranging from 9.5 to 14.5 metres, will be installed along the Mumbai-Ahmedabad High Speed Rail (MAHSR) corridor. The masts will support the complete 2×25 kV overhead traction power system, including overhead wires, earthing arrangements, fittings, and other accessories required for bullet train operations.

“To ensure uninterrupted traction power, a network of Traction Substations (TSS) and Distribution Substations (DSS) is being developed along the Mumbai–Ahmedabad High Speed Rail corridor,” the ministry, said in a release.
