Compact and reliable traction transformers to boost railways and support economic growth
ABB has won an order from Alstom to supply 1600 traction transformers for 800 new electric freight locomotives in India. The new locomotives will expand Indian Railways’ capacity, easing congestion on busy routes for both freight and passenger services. The transformers will be manufactured locally in ABB’s Vadodara facility in the western Indian state of Gujarat, supporting the government’s ‘Make in India’ initiative to encourage manufacturing in the country.
Indian Railways operates the largest rail network in Asia, and is the world’s second-largest rail network operated under single management. The company moves more than 12,500 trains and 23 million passengers daily, equivalent to the population of Australia.
ABB will supply 25 kilovolt (kV)/50 hertz (Hz) underframe traction transformers for the 800 locomotives (2 units per locomotive). The compact transformers are designed for the most demanding conditions, including extreme temperatures and voltage fluctuations. They will support heavy freight loads over long distance haulage under rigorous conditions, including steep inclines.
“ABB has been supplying traction transformers for Alstom’s electrical locomotives for more than a decade and this order confirms our position as a supplier of choice and a reliable long-term technology partner,” said Claudio Facchin, president of ABB’s Power Grids division. “These state-of-the-art transformers will be locally manufactured and are an example of how ABB delivers differentiated customer value by leveraging its technology strengths and global footprint, as part of our Next Level strategy.”
Traction transformers feed power at safe voltages to essential train functions like traction, brakes, lighting, heating and ventilation, as well as passenger information, signaling and communication. Used by rail operators around the globe, ABB traction transformers are manufactured at its plants in Switzerland, India and China, and provide the highest levels of availability and reliability for uninterrupted train service.

KRNA to deploy LTE-R technology for modernization of communications network supporting mission-critical services, such as signaling at speeds of up to 250 km/h
Espoo, Finland – Nokia has been selected by the Korea Rail Network Authority (KRNA) as a supplier for the world’s first LTE-R mobile broadband network to support railway operations and employee services. The network will be deployed on a railway line between Wonju and Gangneung as part of preparations for the major international sporting event being hosted by the country in 2018. KRNA is responsible for the development and maintenance of railway infrastructure in South Korea as well as a number of other countries.
The communications network for KRNA will be based on LTE-R technology, a version of 4G LTE technology that is being developed to meet the mission-critical service requirements of railway operators. The network will support both operational and maintenance services on a high-speed commercial railway line operating at speeds of up to 250 km/h.
KRNA’s LTE-R network will provide secure, reliable, high-speed connectivity between trains, stations and other railway facilities between Wonju and Gangneung. The network will also be designed to interoperate with other LTE networks supporting public safety and maritime operations as well as legacy VHS (very high frequency) and TRS (trunked radio system) radio networks. This project is intended to serve as a model for future LTE-R deployments, and help further define LTE-R standardization efforts.
For this project, Nokia will supply radio access network (RAN) base stations (eNodeBs) along with Nokia NetAct(TM), the first major virtualized network management software for mobile networks. NetAct delivers best-in-class applications for the railway operations and employee services management of KRNA. It also delivers advanced assurance capabilities as part of Nokia’s comprehensive, multi-domain Service Assurance program, which provides closed-loop automation to drive greater network agility and optimization. Nokia systems integration and deployment services will help to establish the new LTE-R network.
Andrew Cope, head of Korea at Nokia, said: “South Korea has been a world leader in the use of mobile broadband technology to make public services of all kinds safer, more efficient and reliable. With a thirty-year history in the delivery of GSM-R mobile networking technology for railways, and as a pioneer in the development of LTE-R solutions, we are pleased to partner with KRNA to bring these cutting edge capabilities to the country as they prepare to host one of the world’s premier sporting events.”
