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.

Tuned In

Spring is when large-scale model railroaders with their green thumbs plant and prune colorful foliage grown nearly to scale. In some areas, maintaining outdoor layouts is quite challenging because of changing weather. Nancy Norris, an author who builds garden railroads professionally, says some plant varieties have become more difficult to grow in certain Hardiness Zones. In some cases it means garden railroaders having to put more emphasis on growing native plants rather than relying on varieties more susceptible to extreme conditions. She recommends new gardeners consult with their local nurseries for the best choices for an outdoor layout. Norris also has a few recommendations of her own.

Tariffs Cause Concern

Sweeping tariffs imposed on goods imported into the United States are stirring model railroad manufacturers. As a result, model railroading and other hobbies will cost more. In February the U.S. applied a 10 percent tariff on goods imported from China, and the tax has since escalated. Suppliers – including Athearn, InterMountain Railway Co., Broadway Limited, Rapido Trains and ScaleTrains – have been putting dealers and customers on notice that prices will increase tariffs are implemented.

Managing Freight Cars

The first rule of railroading is “expect movement on any track at any time in any direction.”  This may seem like an overabundance of caution, but railroading is a dangerous sport. Always expect a train when you’re around the tracks. The second rule of railroading is that there is an exception to every rule. The North American freight car fleet in 2023 consisted of 2.03 million rail cars, according to Railinc’s Umler Equipment Index. Rail car fleet management — how empty cars get dispatched to move to their next loading point — is an ever-moving process and often requires fleet car managers to be nimble.
