Not sure *what* it is... But ONE of them, was leading a 120 car train through town at a fairly rapid (50+) clip. I thought wow, one locomotive for all of that. Then I saw that there was another one of them at the rear end of the train. Two locomotives per coal train out here is common. More and more BNSF is putting locos at both ends of the consist. Especially since you can run them by remote control. I suppose that would make things easier at the dumper. Engineer could get off of the lead locomotive, use the remote to drive it through the dumper, and then get onto the rear (now the front) locomotive, and take the train back to the coal fields. Eliminates the need for a huge loop, not that there is never enough space for said loop, since coal fired plants take up a lot of space, but they can sure as heck take up less space with this arrangement. |

Not the most powerful.Off the top of my head (too busy to look it up), I think the SD70ACe is 4300 HP. GE's C44-9W is 4400 HP, and each manufacturer has a 6000 HP locomotive (SD90 for EMD; AC60CW for GE), although both had a lot of teething problems. |

I thought some CP, CERX, and even a few UP SD9043MACs were eventually given the 256H four stroke engine. It's too bad they had to go with the 16-710G3C engine when they could have dropped the 20-710G3B from the SD80MAC and given the railroads a 5000hp SD9050MAC.However, I haven't heard of any orders for either the EMD 256H or GE's HDL engine lately. It seems the horsepower wars Trains reported on 10 years ago have faded. It is funny that you can draw a distinct line between the SD45/U36C/C636 in the late 1960s and early 1970s and the SD70/C40-8/MK5000(?) in the mid 1990s, and then between moderation of the SD40-2 and C30-7 in the mid 1970s and the SD70ACe and ES44AC/DC these days. There seems to almost be a periodic cycle of advances in motive power followed by utter conservatism on the part of the railroads. Way we're going it seems like in the late 2010s we should see the next round of motive power advances, and those should culminate by the mid 2020s. |

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. |

If the RRs got it about electrification we could see "E90s" that would only be limited by drawbar specs. A new generation of Little Joe's would be cool! |

AEM7 was built more for speed than for continuous high tractive effort. They are hardly the most efficient locomotive for moving freight. |

I think that it's an important enough issue that we should spend money on it. As usual California will probably take the lead. Our local air agency (SCAQMD) is planning to adopt emission limits for trains that are idling. They are being sued by BNSF so they haven't been able to enact them yet. |

I've recently seen an article in Scientific American about the prospects for very low sulfer synthetic diesel fuel made from lignite and brown coal. Apparantly we have tons of lignite which the powerplants and steel mills don't want to burn but could be extremely useful if turned into synthetic diesel fuel. Through several sulfer reduction processes the diesel fuel that results from the coal liquifaction could be cleaner than the diesel fuel which comes refined crude oil. If the coal derived diesel fuel can be used without modification in the existing diesel locomotive fleet then a significant portion of our transportation infrastructure could be insulated from foreign demand or supply fluctuations all while reducing emissions. I've always wanted to see the railroads electrify to accomplish these things, but when compared to coal burning powerplants it could well be cheaper and have a greater impact on emissions to switch to coal derived diesel.There'd be an odd symmetry to this technology since it'd bring the railroads back to being powered by the coal mines that they serve, just as the steam locomotive fleet did more than 50 years ago. |

Ok, I know there are several figures out there for most electrics and I strongly suspect that those figures are the short term overloads for both locomotives. The manual wouldn't happen to specify whether those numbers are continuous or overload are they? I believe the continuous rating for the ALP46 is something like 8000hp, and between 5000 and 6000 horsepower for the AEM7 and ALP44. |

Even if the dedicated plants burned diesel, and they would not,it would be cleaner. And w/ regen brajing they can be much more efficient. At the very least the 'Alameda Corridor' should be electrified . |

In addition to the emissions problems pointed out by other folks there's something to be said for having a critical portion of our transport infrastructure powered by a domestically produced source of fuel as possible. Without the railroads the country literally doesn't move, so it should be imperative that we take steps to eliminate the possibility of foreign supply problems from interfering with the operation of the railroads. Whether this comes from electrification, biodiesel, or synthetic diesel I don't really care. Right now with crude oil fluctuating the way it does we're only hurting ourselves and placing the entire country in danger by using that precarious commodity to move our economy. Railroads are perhaps the easiest thing to wean off our addiction to oil, and as some have mentioned it may be a good idea to electrify things like Cajon Pass and its line into LA, while in other parts of the country coal-based synthetic diesel may work out. |

Sorry, but no such information was given - just 10,000 diesel equivalent horse power & a starting tractive effort of 71,000 Lbs.Also 1,000 KW of HEP. |
