Rivet Counter HO Scale Wabtec C44ACM, Union Pacific/New Small Flag Scheme/Shield Nose Logo

The Rivet Counter™ series C44ACM is the definitive HO Scale model of Union Pacific’s modernized AC4400CW locomotives. Our model combines smooth operating performance with unparalleled railroad, road number, and era specific™ details along with industry-leading LED lighting features. 

From early 2018 through 2025, Union Pacific contracted with GE, now Wabtec, to rebuild 1,030 aging locomotives. This modernization program upgraded hundreds of AC4400CW series locomotives as well as many DASH 9 and AC6000CW varieties. The upgrades included an upgraded control system, wiring and high-pressure common rail fuel system for increased fuel economy and reliability. Externally, multiple changes were also made to the cabs, long hood cabinets and radiators.
