CPKC Completes 170-Unit CA$800M Locomotive Fleet Renewal

CALGARY, CANADA – Canadian Pacific Kansas City (CPKC) received the 170th and final Wabtec Evolution Series ET44AC Tier 4 locomotive in June 2026, closing out a CA$800 million multiyear capital program to modernize the railroad’s road locomotive fleet. The first unit under this order was delivered in May 2025, according to a CPKC press release.

What Is the Full Scope of This Project?

CPKC’s CA$800 million capital program delivered 170 Wabtec ET44AC Tier 4 locomotives over approximately 13 months, replacing older Tier 3 and legacy diesel units across the railroad’s combined Canadian-Pacific-Kansas City network.

Each ET44AC locomotive is equipped with a U.S. EPA-certified Tier 4 diesel engine, advanced traction control systems, and redesigned cooling architecture. The railroad stated the new units will cut nitrogen oxide and particulate matter emissions compared to Tier 3 predecessors while improving fuel economy and mechanical reliability. Baden Tidd, vice president of mechanical-locomotive at CPKC, described the acquisition as “a smart investment in the strength and reliability of our fleet.” No per-unit cost breakdown was disclosed, nor did CPKC specify which corridors or service lanes would receive priority deployment.

Key Project Data

How Does This Compare to Similar Projects?

The CPKC order of 170 units sits in the upper tier of North American Tier 4 locomotive procurement programs. Union Pacific acquired 200 EMD SD70ACe-T4 locomotives from Progress Rail between 2016 and 2022, while Canadian National placed orders for approximately 125 Tier 4 units from Wabtec across multiple procurement cycles through 2024. The CPKC program’s CA$800 million total implies an average unit cost of roughly CA$4.7 million per locomotive, consistent with the CA$4.5–$5.0 million per-unit range observed in comparable North American Tier 4 orders, though CPKC did not confirm an individual unit price.

The broader freight market context supports the timing of this fleet investment. U.S. rail carloads rose 1.5% to 11,508,767 in 2025—the largest annual gain since 2001—while intermodal volume climbed 1.5% to 14.06 million units, the second-highest annual total recorded. Freight gains became more widespread across the rail network heading into 2026, according to the 37th State of Logistics Report. (Source: Logistics Management, 2026) CPKC did not publicly link the fleet renewal directly to these volume trends, nor has the railroad disclosed the emissions reduction tonnage expected from the new Tier 4 fleet.

Editor’s Analysis

CPKC’s completion of this 170-unit program signals a decisive shift from fleet expansion to fleet efficiency across the merged network. The CA$800 million allocation—executed over a relatively compressed delivery window—suggests CPKC prioritized rapid replacement of high-maintenance legacy power rather than phased experimentation. With U.S. carloads posting their strongest annual gain in over two decades and intermodal hovering near record territory heading into 2026, locomotive availability and fuel cost exposure become operational levers that directly affect service reliability and margin. The absence of route-level deployment disclosure leaves unanswered questions about whether CPKC is concentrating these units on long-haul transcontinental corridors or distributing them across secondary lines where Tier 3 units remain in service. The 2025 Logistics Management data confirms rail freight demand is broadening—not just rebounding—giving locomotive modernization programs like this one a stronger economic undercurrent than fleet-replacement cycles undertaken during the 2019–2020 freight recession.

FAQ

Q: What makes the Wabtec ET44AC Tier 4 different from older CPKC locomotives?
A: The ET44AC uses a U.S. EPA Tier 4-certified diesel engine that reduces nitrogen oxides and particulate matter emissions compared to Tier 3 units, and includes advanced traction control and redesigned cooling systems for improved fuel economy and reliability.

Q: How much did CPKC pay per locomotive in this order?
A: CPKC did not disclose a per-unit price. Based on the CA$800 million total for 170 units, the implied average is approximately CA$4.7 million per locomotive, consistent with comparable North American Tier 4 orders.

Q: Where will these new locomotives operate on the CPKC network?
A: CPKC has not publicly disclosed which corridors or service lanes will receive the new ET44AC units. The railroad operates across Canada, the United States, and Mexico, and the locomotives could be deployed on any segment of that network.
