Siemens Mobility delivers first D9 freight locomotives to Indian Railways

Siemens Mobility has delivered the first D9 electric freight locomotives to Indian Railways for commercial operations, marking the initial phase of a 1,200-unit supply contract.

The project also includes the commissioning of the first maintenance depot in Visakhapatnam, forming part of a four-location service network across India.

High-capacity electric freight locomotives
The D9 locomotives are designed for heavy freight operations, with a power output of 9,000 horsepower and a maximum operating speed of 120 km/h. Each locomotive can haul loads of up to 5,800 tonnes under standard operating conditions.

With an axle load of 22.5 tonnes and a six-axle configuration, the locomotives are engineered for high traction performance and efficient long-distance freight transport.

Compliance with international standards
The D9 platform is the first rolling stock in India to be tested according to the European standard EN 14363, which defines requirements for running behavior and dynamic performance of railway vehicles.

This validation supports operational stability and interoperability under defined testing conditions.

Digital systems for performance optimization
The locomotives are equipped with digital monitoring and analytics through the Railigent X platform. This system enables condition monitoring, predictive maintenance, and data-driven performance optimization.

These capabilities support improved fleet availability and reduced unplanned downtime through continuous system diagnostics.

Lifecycle service and maintenance network
The project is structured as a lifecycle partnership, covering design, manufacturing, commissioning, and 35 years of maintenance services. Maintenance operations will be conducted through four depots located in Visakhapatnam, Raipur, Kharagpur, and Pune.

Services include spare parts management, maintenance planning, and operational reporting, supported by digital tools for performance tracking.

Role in freight transport expansion
The deployment of the D9 locomotives supports efforts to increase the share of rail freight transport in India’s logistics network. Enhanced hauling capacity and operational efficiency contribute to higher throughput and reduced reliance on alternative transport modes.

Through this project, Siemens Mobility continues its collaboration with Indian Railways in developing electrified rail infrastructure and high-capacity rolling stock.
