ABB has won orders worth around USD 80 million from Stadler for energy-efficient traction and high-performance battery technologies for high-capacity commuter trains. Many of these trains will strengthen the short-distance transportation network in Spain serving more than one million commuters every day in some of Spain’s largest cities such as Madrid and Barcelona. The orders also include traction equipment for new locomotives.The orders include state-of-the-art compact traction converters and high-power lithium-ion battery based on-board energy storage systems to power 59 new generation high-capacity double-deck commuter trains for Spain’s state-owned rail operator Renfe. The orders were booked in the fourth quarter of 2021.ABB technologies will help to increase reliable service for commuters in Spain’s major metropolitan areas including Madrid and Barcelona.The new high-capacity commuter trains will operate on 3kV direct current overhead lines and are also equipped with traction batteries for emergency use and depot maneuvering. The new fleet, equipped with highly compact, efficient, and all roof mounted ABB traction technology, will increase passenger capacity, while at the same time contributing to more sustainable transportation.ABB’s lithium-ion on-board energy storage system is used as alternative power source to help ensure reliable and punctual train services in the event of catenary failure. The energy storage system may also serve as the primary power source for maneuvering in depots or cleaning rail yards without catenary supply infrastructure.The compact traction equipment converts the electrical energy from the overhead power line or battery into the needed voltage and frequency to drive the traction motors. Its compact design and high energy efficiency performance will save space, reduce weight, and save energy in these trains.
