Looking for a modern, highly detailed locomotive reflecting the latest evolution of the fleet? The ScaleTrains Wabtec/GE C44ACM, in its premium Rivet Counter line, in Union Pacific (New Small Flag Scheme) colors, is exactly that kind of standout piece.
Between 2018 and 2025, Union Pacific contracted with Wabtec (formerly GE) for a deep rebuild of more than a thousand aging AC4400CWs — the largest modernization program in rail history. The result, the C44ACM ("M" for Modernization; CM44AC on CSX), is a 4,400 hp six-axle unit with redesigned cabs, updated carbody cabinets and radiators. This version recreates a Union Pacific unit in the new small-flag scheme, with the shield only on the nose (third scheme, finalized in 2022).
