The AC6000CW is a 6,000-horsepower (4,500 kW) diesel electric locomotive built by GE Transportation. This locomotive, along with the EMD SD90MAC, is among the most powerful single-engined diesel locomotives in the world. The only locomotive to surpass them is the dual-engine 6,600-horsepower (4,900 kW) EMD DDA40X.
