CSX has extended its AC4400 modernization program with Wabtec to give the remaining 200-plus locomotives in its 460-plus unit fleet improved fuel efficiency, reliability, utilization and tractive effort. Wabtec will perform the modernizations at its U.S. locomotive plants from 2024 to 2028. The contract adds to the 260 modernizations that CSX previously ordered, the majority of which have been delivered.

The modernization program includes a suite of Wabtec hardware, such as the FDL Advantage (FDLA) engine upgrade, and digital solutions like LOCOTROL® Expanded Architecture (LXA). “Those technologies will work to enable the locomotives to deliver up to 8% fuel savings and provide approximately 170 tons of carbon reduction per locomotive per year,” Wabtec said. “It is Wabtec’s goal for CSX’s total order to realize approximately 35,000 tons in annual carbon reductions. Additionally, the modernizations will extend the locomotives’ lives for several more years. It also will target to provide an increase in reliability of up to 35% and tractive effort by up to 14%. CSX’s AC4400 fleet will have greater availability and increased capabilities at reduced operating costs.”

CSX noted its fleet modernization effort is part of the railroad’s “expanded use of innovative fuel-saving locomotive technologies and supplier engagement” to achieve its sustainability goals. “This modernization order is part of our commitment to deliver excellence for our customers, shareholders, employees and communities,” said CSX Executive Vice President and Chief Operating Officer Mike Cory. “Wabtec’s modernization program enables us to maximize the capabilities of our existing fleet. The upgrades will improve asset reliability, allowing us to move more freight with fewer locomotives, which also will help reduce our carbon emissions footprint.”

“The modernizations will enable CSX to maximize the value of its existing AC4400 fleet,” said Wabtec Executive Vice President Sales and Marketing, and Chief Commercial Officer-Americas Gina Trombley. “By installing state-of-the-art technology on these locomotives, we are helping to improve locomotive performance, fuel efficiency and reliability, while also reducing on-going maintenance costs. This modernized fleet is well-positioned to support CSX’s long-term sustainability and service goals.”
