Quoting Zkpilot (Reply 2): why don't they install overhead electric lines and use electric locomotives? no problem with O2 starvation then! They'd be able to operate at a faster speed. |
Quoting Mir (Reply 5): Possibly because the lines have long stretches of nothingness, and maintaining the wires would be cost-prohibitive. |
Quoting WunalaYann (Reply 6):
Honestly, if all the major networks in Europe can do it, there is no receivable reason why it could not be done in the world's largest and most prosperous economy... |
Quoting Mir (Reply 5): Electrified lines are practically non-existant in the US outside of public transportation and the main Boston-New York-Washington line. I have no idea why. Possibly because the lines have long stretches of nothingness, and maintaining the wires would be cost-prohibitive. |

Quoting Klaus (Reply 7): I'd also expect that you could make those diesels a whole lot cleaner if you really cared; But it would again be a matter of cost. |
Quoting Jush (Reply 10): Well if you look at the height of the tunnel I wouldn't double stack containers in the USA either |

Quoting ZANL188 (Reply 11): Electrification has been done in the U.S. (particularly in tunnels) and then removed later for the reasons you site. Strikingly, electrification went by the wayside about the same time steam did and, in many cases, for the same reason - diesels did not require the infrastructure that steam and electric did. |
Quoting Klaus (Reply 7): The problem is that a smaller population is stretched across a larger area in the USA. That doesn't make it impossible, but it's still a matter of costs, especially in a country which simply doesn't support the necessary investment and blows all its subsidies on road and air traffic. |
Quoting Halls120 (Reply 16): After all, people are clamoring for the ability to travel coast to coast by train |
Quoting Halls120 (Reply 16): Right - we should stop investing in air travel, and electrify the entire rail system. After all, people are clamoring for the ability to travel coast to coast by train. It's so efficient, after all. |
Quoting AsstChiefMark (Reply 17): If you could operate a TGV at maximum speed nonstop between New York and Los Angeles, the trip would still take 14 hours. That's assuming you have a straight, flat track between the cities. |

Quoting Klaus (Reply 18): The challenges in the USA are certainly not identical, but still related. |
Quoting Halls120 (Reply 20): And I doubt that you could run such a train without stopping. After all, the union rules would never permit it. |
Quoting Halls120 (Reply 20): Yes, if we had planned better, we could have better train connectivity in those places where it is logical to have it. But coast to coast rail service isn't logical, given the vast distances that one covers in the US. |
Quoting Klaus (Reply 21): Not that many people travel by ICE from Munich to Hamburg either, but the train will make the entire run nevertheless, with a few stops in between. |
Quoting Halls120 (Reply 20): And I doubt that you could run such a train without stopping. After all, the union rules would never permit it. |
Quoting Trekster (Reply 22): In this day and age of Eniromental stuff, that train just takes the biscuit. There should not be that amount of smoke being released into the air... |
Quoting Halls120 (Reply 23): Your attempt to suggest that if the US had done what Germany has done with its train system simply isn't logical. The differences in distances between our major cities and your major cities is vast. |
Quoting ZANL188 (Reply 25): Diesel-electric locomotives generate their electricity on board vs sending it hundreds of miles across country as would have to be done with an electrified line in the U.S. |
Quoting ZANL188 (Reply 25): Electrification of rail lines doesn't remove the carbon footprint of a train, it just moves it elsewhere. |
Quoting Klaus (Reply 27): And I'm pretty sure that a sizable portion (if not the majority) of US domestic travelling is done over far shorter distances. |
Quoting Klaus (Reply 27): And modern electric trains feed their braking energy back into the network while diesel trains simply vent it as heat. |
Quoting Klaus (Reply 27): A diesel train will always have a major CO2 footprint. Electric trains can easily be fed with renewable energy (hydroelectric, wind, solar, geothermal...) and often are. |
Quoting ZANL188 (Reply 29): True for places like New York & possibly LA, but for most of the country to get from one major city to another involves longer distances. |
Quoting ZANL188 (Reply 29): And if there isn't another train or town nearby to use that energy a fair portion of it will be lost.... |
Quoting ZANL188 (Reply 29): BTW: Hybrid diesels are available on the market. |
Quoting ZANL188 (Reply 29): Ok carbon was a poor word to use.. The enviromental impact is moved elsewhere regardless... |
Quoting ZANL188 (Reply 29): BTW: How do the French power the TGV?? |
Quoting Trekster (Reply 22): In this day and age of Eniromental stuff, that train just takes the biscuit. There should not be that amount of smoke being released into the air... |
Quoting ZANL188 (Reply 29): BTW: Hybrid diesels are available on the market. |
Quoting Klaus (Reply 30): If they were to use braking energy, they'd have to lug around rather massive batteries which would again reduce efficiency. |
Quoting Klaus (Reply 30): Heavily subsidized nuclear energy; |
Quoting VHVXB (Reply 3): Or they could install fans at both ends of the tunnel to suck out the fumes |

Quoting ZANL188 (Reply 33): It matters not... Locomotives need ballast to achieve traction performance targets anyway. Swap batteries for ballast = no loss of efficiency |
Quoting ZANL188 (Reply 33): Exactly. Electrification only moves the environmental impact elsewhere, in this case to a reactor. Hydro moves it to a dam where the fish can't get upstream, etc, etc, etc |
Quoting AsstChiefMark (Reply 24): Quoting Halls120 (Reply 20):And I doubt that you could run such a train without stopping. After all, the union rules would never permit it. I'm pointing out that our country is so damned big that even high-speed trains would still be undesirable for fast, long distance trains. I'd say anything longer than four hours on a high-speed train operating from city center to city center is about the point at which most Americans would consider flying. |
Quoting Klaus (Reply 27): And I'm pretty sure that a sizable portion (if not the majority) of US domestic travelling is done over far shorter distances. |
Quoting Klaus (Reply 30): Quoting ZANL188 (Reply 29):True for places like New York & possibly LA, but for most of the country to get from one major city to another involves longer distances. Not generally coast-to-coast distances, however. Which was my point. In Germany rail is a good alternative for most domestic flights. In a USA with high-speed trains the percentage would be lower, but still significant. And that ratio would continue to tilt in favour of rail travel with further rising oil prices. |

Quoting Klaus (Reply 35): Modern high-speed trains don't have separate locomotives. |
Quoting Klaus (Reply 35): There's still a big difference in relative impact in favour of renewables. |
Quoting Pyrex (Reply 37): The transsiberian railway, the longest railway track in the world, is fully electrified, and I bet maintaining power lines in Siberia is much harder than in Arizona... |
Quoting ZANL188 (Reply 39): Unfortunately the transiberian was politically motivated to help open up that part of the world. |

Quoting 57AZ (Reply 41): However, there are plenty of city pairs that could support high speed rail that are not linked. Houston-New Orleans: 340 miles Orlando-Tampa: 80 miles Orlando-Jacksonville-130 miles Orlando-Miami: 230 miles Jacksonville-Atlanta: 320 miles Atlanta-Chattanooga: 130 miles Chattanooga-Nashville: 140 miles |
Quoting Halls120 (Reply 42): A similar system in the US just isn't feasible. |
Quoting Halls120 (Reply 36): You are? Based on what? Your gut feeling? |
Quoting Halls120 (Reply 36): Based on what evidence? |
Quoting Halls120 (Reply 36): But let's look at some other city pairs. |
Quoting 57AZ (Reply 41): However, there are plenty of city pairs that could support high speed rail that are not linked. |
Quoting ZANL188 (Reply 39): But we are talking about freight locomotives, hybrids inparticular |
Quoting ZANL188 (Reply 39): But there is always an environmental impact even with renewables. |
Quoting ZANL188 (Reply 39): BTW: Ever heard of biodiesel? |
Quoting Klaus (Reply 44): I wasn't at this point. Freight is a different matter again. Flying, for instance, plays a much smaller role there. |
Quoting Klaus (Reply 44): You couldn't impact the environment that much worse if you tried! |
Quoting Halls120 (Reply 42): There are indeed a number of city pairs in the US that could probably support high speed rail. But not on the order of DB, which is a national system. A similar system in the US just isn't feasible. |
Quoting Klaus (Reply 18): The challenges in the USA are certainly not identical, but still related. |
Quoting 57AZ (Reply 43): You'd be surprised at how many people here in the US would consider short-medium haul passenger rail trips over automobiles or airlines if they had a convenient, reasonably economical alternative. |
Quoting Klaus (Reply 44): Quoting Halls120 (Reply 36):You are? Based on what? Your gut feeling? Are you telling me that all the US domestic flights except a negligible fraction are coast-to-coast or comparable in distance? That looks rather implausible. The distance distribution usually sees a larger frequency of lower distances, with decreasing frequency at growing distances. Having the major population centers at the US western and eastern coasts will skew that distribution somewhat, but I don't see why the principle suddenly wouldn't apply any more at all. |
Quoting Klaus (Reply 44): Quoting Halls120 (Reply 36):Based on what evidence? Flying has much higher fuel-dependent costs. As much as we all love aviation as such, there are other forms of transportation which are more CO2-efficient, cheaper and even faster on certain distance ranges. Flying starts getting practical at a certain distance; The presence of a decent high-speed rail network pushes that crossover point upwards by a good bit. Other factors can further move it up or down. Overall costs, delays, overhead and reliability factors all factor in there. |
Quoting ZANL188 (Reply 45): Ah yes you were speaking of a non-existent high speed hybrid diesel passenger locomotive then I presume? |
Quoting ZANL188 (Reply 45): In terms of potential environmental impact I believe the TGV (powered by nuclear generating stations) takes the cake.... |
Quoting Halls120 (Reply 47): Notice I'm not disputing your claim- just asking you to support it with something other than your opinion. |
Quoting Halls120 (Reply 47): I'm going to run right down to my Congressman's office tomorrow morning and tell him we need high speed rail in the US. When he asks why I think it will work in the US, I'll just hand him a copy of your post above. I'm sure a bill will be forthcoming immediately! |
