The GE Locomotive That Silenced EMD in 1994

GE’s AC4400CW didn’t just challenge EMD in the mid-1990s, it changed the rules. This video lays out how EMD’s DC-traction stronghold, built on SD40-2 era reliability, ran into GE’s AC traction, smarter controls, and a 4,400 hp package that could pull heavier trains with fewer units in real service. We break down what actually changed under the hood. From GTO-based inverters and individual axle control to three-phase induction motors that cut wheel slip and boosted adhesion, you’ll see why continuous tractive effort mattered more than brochure horsepower. We compare AC44 performance to SD60 and early SD70 power, and show how diagnostics plus modular electronics saved railroads time and money in the shop. Then we follow the buying wave that proved it out in the field. CSX trials, Canadian Pacific’s big 1995 order, BNSF’s scale, and Union Pacific’s coal program pushed AC traction from experiment to standard. By the end of the decade GE had momentum, EMD was scrambling to answer, and the market had flipped. Watch to see the technical and operational levers that shifted share, and tell us where AC traction delivered the biggest gains on your railroad. --------- We do not fully own the material compiled in this video.
