As others have said there are other more powerful locomotives than the 4400hp SD70ACe. The AC6000CW, SD90MAC, SD80MAC, and MK5000 among them, however almost all of them have been sales flops. I suppose given the Northeastern US bias of the membership it's worth noting that the tiny AEM7 beats all those units with a 7000hp rating, and both the ALP46 and HHP8 manage an 8000hp rating. EMD even built a 10,000hp electric locomotive back in the energy crisis of the 1970s. The GM10B was a fairly basic electric locomotive, quite similar to the GG1 in operation, since it used AC motors driven by a variable voltage off the transformer (rather than variable frequency as today's AC locos do), but it was of an unprecedented scale.The high horsepower locomotives of the 1970s seem to have failed because the manufacturers couldn't put together a package which effectively put the power to the rail. Today there are much better solutions for such things, so a 6000 horsepower diesel need not use two prime movers, and I believe Siemens has delivered a 10,000 hp Bo-Bo electric locomotive to a Swiss freight carrier. |
