The order is to design, supply and install 40 alternating current (AC) traction systems for dual-cab high horsepower diesel engine locomotives, Siemens Ltd said in a statement.
"The advent of IGBTs (insulated-gate bipolar transistor) has yielded strong efficiency gains in electric drive technology," said Tilak Raj Seth, Executive Vice-President and CEO, Mobility Division, Siemens Ltd.
The AC traction Systems will be produced at Nashik Factory of Siemens. The systems have been developed based on the state-of-the-art IGBTs technology.
The principle benefit of IGBTs over Gate Turn-off thyristors (GTOs) is that it reduces the current required, and therefore the heat generated, giving smaller and lighter units.
