Mobility provider Alstom supplies Indian Railways (IR) with 800 Prima T8 electric freight locomotives. The Ni-Cd batteries were supplied by Saft, a subsidiary by Total. The units will be able to haul 6000-tonne freight trains at a maximum speed of 100km/h which can be upgraded to 120km/h.
The locomotives are being supplied under a 3.5 billion Euro contract awarded in 2015 by a joint venture of India’s Ministry of Railways and Alstom. The contract also includes 11 years of maintenance and the construction of a manufacturing plant.
Each locomotive is 38.4m long and has a double Bo-Bo wheel arrangement. The units weigh 200 tonnes with a 25-tonne axleload, and 180 tonnes with a 22.5-tonne axleload. They can operate in temperatures ranging between -10oC and 50oC. The locomotives also have an Insulated Gate Bipolar Transistor (IGBT) traction system and are designed for regenerative braking.
Commissioning of the first sections of the Eastern and Western Freight Corridors should be completed by the end of 2021.
