Incorporates the Evolution Series diesel engine
Wabtec launches a new model of heavy transport locomotive in the Brazilian rail freight market.
The ES44ACi diesel-electric locomotive will first be delivered to Suzano, MRS and Rumo in the coming weeks, the company said.
“The ES44ACi locomotive features the Evolution Series diesel engine, producing the same 4500 HP with just 12 cylinders as its predecessor the 16 cylinder FDL engine,” said Daniela Ornelas, Vice President of Products at Wabtec. “This represents greater fuel efficiency and lower emissions, thanks to a project aimed at thermal efficiency of combustion combined with a dual intake air cooling system adopted in these turbocharged four-stroke engines equipped with a electronic fuel injection.”
This engine technology allows the locomotive to reduce fuel consumption and emissions by more than 5% compared to its predecessor. The high-strength materials used in the ES44ACi also improve the reliability of the diesel engine and significantly increase major service intervals by approximately 28%, thereby reducing operating costs throughout the locomotive’s life cycle.
The effort to bring the ES44ACi locomotive to the Brazilian rail market was an eight-year project with operators. The goal is to improve Brazil’s heavy-haul rail network and promote sustainability, the company said. To date, the company has already secured orders for 25 locomotives from Suzano, Rumo and MRS.
“Our sustainability vision is grounded in operating in an ethical and socially responsible manner, maintaining a culture of safety, protecting the environment, supporting our communities and developing our people,” said Juliano Andrade, Latam sales manager at Wabtec. “That was the main concept applied to the ES44ACi. We therefore want to build a better and more sustainable future.
Rumo is the largest rail operator in Brazil and new fleet acquisitions reinforce technology initiatives focused on operational efficiency and safety.
“Our priority is to promote increasingly sustainable operations, not only economically but also socially and environmentally,” said Marcus Rogério Vianna Jorge, director of Undercarriage at Rumo. “With the constant renewal of the fleet, we have gained in efficiency in the flow of agricultural and industrial loads, in addition to contributing significantly to the reduction of emissions.”
For MRS, a logistics operator that manages a 1643 km rail network in the states of Minas Gerais, Rio de Janeiro and São Paulo, the ES44ACi will help optimize its system. The new locomotive adds more technology and advancements to the national rail sector, whose concession renewal is heading towards the home stretch in the Federal Court of Auditors.
“MRS has invested heavily in the expansion of its fleet to contribute even more to the efficiency of the national logistics system, generating energy efficiency gains,” said General Manager Maintenance Engineering at MRS, Anelise Salzani. . “We are acquiring the ES44ACi because we expect it to be a high horsepower, low diesel consumption locomotive. It integrates two pillars of the company: the search for more productivity and the reduction of the volume of emissions, the consolidation of a more sustainable operation.
