Union Pacific, Wabtec sign historic $1 billion deal to modernize AC4400 and AC6000 locomotives

July 28, 2022

News

Union Pacific Railroad signed a historic deal with Wabtec Corp. this week for 600 locomotive modernizations featuring a suite of digital solutions and innovations. The agreement, worth more than $1 billion, is the largest investment in modernized locomotives in rail industry history, and part of UP’s fleet strategy to move more freight efficiently and sustainably across its service territory.

Wabtec will modernize 525 of UP’s AC4400 and AC6000 locomotives, as well as 75 Dash-9 locomotives. The modernized locomotives will feature a suite of digital solutions and innovations such as the FDL Advantage engine upgrade and Modular Control Architecture, a next-generation controls technology that is applicable throughout Wabtec’s locomotive installed base.

The modernizations will extend the locomotive’s life and provide benefits, including a fuel efficiency improvement of up to 18 percent; more than 80 percent increase in reliability; and haulage ability increase of more than 55 percent.

“UP is taking thoughtful, deliberate steps to reduce our environmental impact and to help our partners improve theirs,” said Lance Fritz, Chairman, UP president and CEO. “Wabtec’s modernization program helps make our existing fleet more fuel efficient, capable and reliable. The resulting increased tractive power enables us to move more freight with fewer locomotives, which improves efficiency and reduces emissions.”

The initiative comes as the industry looks to sustainably meet the growing demands on the rail network by maximizing and extending the capabilities of locomotive fleets. It also helps place UP on a path to achieve its aggressive emissions target to reduce absolute Scope 1 and 2 greenhouse gas (GHG) emissions by 26 percent by 2030 from a 2018 baseline, and on a path to net zero emissions by 2050.

The modernizations also support UP customers’ efforts to meet their own carbon reduction targets.

“Modernizations are a game changer for our customers offering the ability to realize significantly more value out of existing locomotive assets,” said Rafael Santana, Wabtec president and CEO. “By customizing these solutions for our customers and installing state-of-the-art technology, we are helping our customers realize outcomes including increased tractive effort, fuel efficiency, reliability, and adhesion, which reduce maintenance, repair and overhaul expenses. These fleet benefits will support UP’s sustainable service improvements and long-term growth strategy.”

Modernizations to reduce emissions, contribute to circular economy

The modernizations will provide approximately 350 tons of carbon reduction per locomotive per year. The total order will enable UP to realize approximately 210,000 tons in annual emission reductions, equivalent of removing emissions from nearly 45,000 passenger cars per year.

The upgrades also support the circular economy with more than half the locomotive’s weight being reused. Approximately 70,000 tons of steel will be reused and recycled – the equivalent of more than 51,000 passenger cars – for the order.

The deal is the third major modernization order from UP since 2018, with more than 1,030 locomotives upon completion in 2025. Wabtec will perform the upgrades at its plants in the United States, including Fort Worth, TX. Deliveries are expected to begin in 2023.

O Triad

The O-scale Reader & Caney Creek, the Virginian Railway and the Cheapskate & Ohio are distinctly different. Well-known among Southwest O-scalers, the protolance 2-rail Virginian is spectacularly scenicked and spans over 1,200 square feet. Same with the freelance Cheapskate & Ohio, still mostly under construction. It showcases fine-scale 2-rail modeling integrated with hi-rail AC toy trains. The around-the-walls Reader & Caney Creek is proof that 2-rail doesn’t require a ballroom. While they share a size more associated with nostalgia and collecting than fine-scale model railroading, the layouts embody a very individual spirit. And the goal isn't necessarily running trains.

Craftsman Courtyard

Laser-cut craftsman kit makers on the East Coast are working together to change the dynamic of a model railroad segment traditionally reserved for elite modelers because of its reputation for complex kits requiring extensive handwork. Through affordable, easy-to-assemble wood kits, the companies are attracting the experienced and beginners alike.

Mail on the Rails

For a century, “these couriers” included the railroads and what was known for most if its life as the Railway Mail Service. In 1950 more than 14,000 clerks toiled away sorting mail in Railway Post Offices on 3,000 moving trains.
