SALi – The new locomotive generation for Latin America: A commitment to the “Bioceanic Corridor”

IT IS A CO’CO’ DIESEL-ELECTRIC LOCOMOTIVE WITH AC/AC TRACTION, AN ULTRA-LIGHTWEIGHT DESIGN AND WITH FOREFRONT TECHNOLOGY, TO SUCCESSFULLY FACE THE CHALLENGES ENTAILED IN OPERATING ON METRE-GAUGE TRACK UNDER CONDITIONS OF GREAT ALTITUDE (OVER 5,000 METRES ABOVE SEA-LEVEL) COMBINING A HIGH-POWER OUTPUT AT GREAT ALTITUDE WITH REDUCED FUEL CONSUMPTION PROJECT DEVELOPPED BY STADLER RAIL VALENCIA.

Stadler is specialised in the design of locomotives for international corridors. Following in the wake of its predecessor the EURODUAL in cross-border European rail corridors, SALi, due to its design and performance, is destined to become the benchmark locomotive of the Bioceanic Rail Integration Corridor which, crossing Bolivia, will link the Peruvian port of Ilo with the port of Santos in Brazil.

This locomotive is based on other models of the company including the necessary modifications to operate in South America. With a nominal power of 2500 BHP (1865 kW), even operating at high altitude, it reaches a maximum speed of 100 km/h and its weight can vary between 16 and 18 ton/axle. The monocoque structure, very light and resistant and with AAR design, is reinforced against frontal collisions.

The bogies are characterized by their simple and robust design, low track efforts and high traction capacity. SALi can transport up to 30% more cargo than the current locomotives in the region. The AC traction chain with 6 asynchronous traction motors increases the adhesion performance, reliability and availability of the machine.

SALi features two acoustic and heat-insulated driver’s cabs, to enhance comfort under extreme temperature conditions. It complies with all the safety and visibility requirements, in accordance with the latest trends and ergonomic criteria. The locomotive also includes a modern diagnosis and location system that facilitates the management of fleets to the operator.

Stadler Valencia will supply the first three SALi locomotives to the Bolivian railway operator Empresa Ferroviaria Andina-FCA in 2019.
