    I note that those figues assume the use of internal combustion engines for
    traction.

    How about electric trains ?

    both the 12 valve and the 24 valve are well known and very respected
    around here mate, primarily because they work well.

    at least thats how we judge stuff here in the us old boy.

    You seem to be beyond clueless to the fact that these American
    full-sized diesel pickups do their job while still getting order-of 15
    mpg at gross weights of >15,0000 pounds. They've been common-rail
    injecte turbocharged for several years now, and before that were
    typically HEUI types since the early '90s.

    The rest of the (its lowercase, by the way) world doesn't do any better
    than that.

    The number of kilowatts [horsepower] used is the same so it depends if the
    power is generated from nuclear, orimultion, coal, oil, gas, hydro, wind,
    solar or tidal. In effect you have to go with cost in that case, which is
    the only important measure.

  5. I must say that I am puzzled by your assertion as the numbers were taken
    from 'official' websites. Why do you criticise them so?

    I suspect it is purely because the numbers do not agree with his prior
    claims but do agree with mine and your estimate. Simple as that.

    I have posted the links to perfectly valid figures and will let the reader
    Another failure to understand on your part. Its not a matter of opinion, the
    numbers are what they are, you have none, and I've given plenty.
    Average human weighs in at 200lbs. pile 40 of them in a rail car nd you have
    "bulk transport." You've yet to prove that rail transpor is inefficent,
    quite the opposite, you've proven nothing in that regard. As to cost, that
    isn't a measure of efficiency, and I'm not saying building a rail line is
    cheap. BUT... in the long term, it WILL save huge amounts of fuel, which was
    the original point.

    Sadly, your figures were not accurate, given the assumptions that were used
    to arrive at those figures.
    I've never commented on U.S. data on auto use, so assuming (once again) what
    my opinion is would be just that, an assumption.
    Without a thorough examination of any report that the U.S. Government
    publishes, one has to take into account the funding source and the actual
    data collection agency. Therefore, they are no more accurate than any other
    study source, and possibly much more biased.

    I note that those figues assume the use of internal combustion engines for
    I'm not sure how energy consumption would be measured on these, given the
    method of "fueling" them. I did a brief search, and found that most studies
    measured kW usage over a year, rather than individual units.

    This link provides details of the train weight and passenger loading on a
    light rail system.
    http://www.sacrt.com/lightrail.stm

    I suggest that the lack of data for power use per train is because power use
    varies widely based on load. Load would be difficult to determine, as it
    would be unknown how many passengers were on an entire rail line at one
    given time. Further complicting this, most electric transit systems have
    multiple feed points or "substations". As such, it would be impossible to
    measure all of these points and come up with an accurate estimate of the
    power usage given the mobility of the consumption points. However, if you
    find such data, I'd certainly like to see it.

    Do you abuse some kind of illegal substance?
    Fuel use is well documented in the links I gave you or linked pages thereof.
    It is substantially, very substantially in favour of buses and even private
    cars. There can be no rational dispute of this.
    Here are the figures copied below so that the lazy or plain stupid can read
    them with the minimum of effort.

    Network South East – 108 passenger-miles per gallon,
    Regional services – 123 passenger-miles per gallon,
    Intercity - 123 passenger-miles per gallon,
    System wide average – 115 passenger miles per-gallon. - Similar to a diesel
    powered car containing two people but much less than the 200 passenger–miles
    per gallon available from an express coach with 20 aboard doing 10 miles per
    gallon.



    Note that the coach [bus] is less than half full. These coaches have 55
    seats or more.


    What assumptions do you dispute. If the coach/bus were used at a higher
    capacity the figures would be even more in favour of them. All the
    assumptions are made in favour of the train in order to underline just how
    much more efficient the bus is despite assumptions leaning towards train.

    I have given you links. If the data is too complex for you to manage that is
    your problem. For you to doubt the data accuracy is plain silly. There is no
    possible agenda that would justify your doubt.
    The plain truth is that it does not agree with your view and therefore you
    will not accept its validity.
    Children usually grow out of this at by the time they reach their teens.

    Parameters for conversion of GW-h to litres and gallons are as follows:
    1. Power stations are 37% efficient (up from 35 in 1990) [Source is
    Table 5.5 of the digest of United Kingdom Energy Statistics”].
    2. Transmission losses amounted to 4% [Transport-watch assumption].
    3. The net calorific value of diesel is 42.9 Giga-joules per Tonne and
    the specific gravity is 0.84.
    4. One gallon equates to 4.546 litres
    5. Hence one GW-h is equivalent to (3600 x 1000)/(0.37 x 0.96 x 42.9 x
    0.84) = 0.281 million litres of diesel burnt in buses or to 0.06187 million
    (imperial) gallons.

    If you had read and understood the information I provided you would not need
    to ask the question.
    It ends up with undisputed figures for the UK of a best of an equivalent of
    123 passenger miles per gallon on intercity electrified routes with local
    services falling to a low of 108.

    now that is a hoot. a person from the uk, complaining about the us,
    calling that guy from the us a fantasist. huw, just the fact that you
    are here bitching about the us shows you and pooh butt to be the
    biggest fantasists in existance today. to believe that you uk guys
    can even play in the same league as us us guys proves that. i mean,
    come on. what has the uk done, other than provide a rather basic
    testing ground for dental hygiene? you wanna bitch about our car
    industry? what has the uk ever provided? oh yeah, electronics by
    lucas, the prince of darkness. oh, an triumph, the bike that helped
    invent the mighty wipe. look, we can't use your industry as a bad
    example, because you don't have any. so, while i understand you
    coming on and complaining about the us to take your mind off of the
    uk, don't lose perspective.

    and pooh bear wanting to rip on our military. hey, again, at least we
    have one. i am sure it won't be long before you see proof of that,
    since we will probably have to come over and save your sorry asses
    again.

    geezz, come on. your envy is showing huw.

    Comparisons

    A commuter train carrying 80 passengers requires roughly 710 British
    thermal units (Btu) of energy per passenger per mile, and a trolley
    with 55 passengers uses around 1,050 Btu per passenger mile, and a one
    person car, some 7,380.
    Public transport also saves valuable city space. Buses and trains
    carry more people in each vehicle, and if they operate on their own
    right-of-way (particularly in underground tunnels), can safely run at
    much higher speeds. An underground metro can carry 70,000 passengers
    past a certain point in a single lane in one hour, surface rapid rail
    can carry up to 50,000 people, and a trolley or a bus in a separate
    lane more than 30,000. A lane of private cars with four occupants, by
    contrast, can move only about 8,000 people per hour. ["Out of the car,

    Costs

    Few U.S. drivers realize that, including fuel, maintenance, insurance,
    depreciation, and finance charges on their cars, they pay $34 for
    every 100 miles of driving. On a yearly basis, it costs the average
    solo commuter nearly $1,700 just to get to work. By contrast, the
    average public transport fare is $14 per 100 miles. ["Out of the car,
    into the future" by Marcia D. Lowe. WW, Nov/Dec 1990]
    The first step is to bring to light the hidden costs of driving, such
    as air pollution, municipal services, and road construction and
    repair. Perhaps least-recognized of these public expenses are items
    such as police, fire, and ambulance services required for an
    automobile-centered system. According to an analyses of the salaries
    and personnel time of the Pasadena Police Department in California, 40
    percent of department costs are from accidents, theft, traffic
    control, and other automobile-related items. Extending this finding to
    the entire United States suggests that local governments spend at
    least $60 billion on automobiles. Employer-provided free parking (a
    tax-free fringe benefit) represents another huge subsidy to drivers,
    variously estimated to be worth an additional $12 to $50 billion a
    year. ["Out of the car, into the future" by Marcia D. Lowe. WW,
    Nov/Dec 1990]

    costs two billion dollars per year to Ontario businesses. [Ross

    The Ontario Ministry of Transportation has estimated that the societal
    costs of automobile accidents causing injury and death exceed $1.9
    billion per year, including health costs, policing, repairs, lost
    wages, and other impacts. This is equivalent to roughly $380 per
    taxpayer per year. [Udo Stillich, p. 11; found in: "Transporting

    Energy

    The energy equivalent of 575,000 barrels of oil a day are required to
    produce 10 million cars in the U.S. . [Greenpeace International (1991)
    found in: "The Recycling of Automobiles: A Study of the Scope of the
    "by Mike Carriere / file industry sectors automotive]
    DOT (Department of Transportation [U.S.]) says the average one-way
    commute is about 10 miles. To accomplish this flat, a 3000- pound car
    with a single occupant uses about 65,000 BTUs of energy. It would be
    roughly 3,5 times more energy-efficient to travel in a four-person
    carpool; 7 times more efficient to go by bus; 35 times more efficient
    to go by subway; 60 times more efficient to go by train. ["Motion
    sickness" Friends of the earth. Vol. 21 No. 2 Spring 1991]
    It has been estimated that between 66 and 105 gigajoules of energy are
    needed to produce a motor vehicle, depending on the proportion of
    recycled materials used. This is equivalent to the energy contained in
    between 2000 and 3000 l of gasoline, or the amount of fuel consumed by
    16000 to 26000 km of driving. [A state of the Environment Fact Sheet

  18. You want more internet info????

    From the same source:

    Americans collectively drive nearly as much as the rest of the world
    combined. Not only are they the biggest travelers on the planet, they
    travel interplanetary distances. In 1990 the U.S. auto and truck fleet
    will travel two trillion miles, the distance to the planet Pluto and
    back, 364 times.

    --------------------------------------------------------------------------------
    Feasible One Day Journeys By Car In The USA And Canada


    have had many people ask how far it is possible to travel by car in
    one day in the USA and Canada.
    On rural Interstates you can safely assume an average speed of 60mph
    over a long distance, but on US Highways and state highways it is much
    more difficult to give a figure since the quality and nature of the
    roads can vary (although most are excellent). Also, you may wish to
    stop to look round towns or admire views, and you may encounter the
    occasional delay due to "construction" (road works). A safe working
    figure for an average speed on open roads in the west is probably
    around 50mph, but rather lower through towns, over mountain passes,
    etc. Due to the greater number of towns overall speeds on normal roads
    tend to be less in the east than in the west.

    Alpine, Texas to Dalhart, Texas (480 miles)

    A fascinating ride as the country changes from the mountainous area
    near Alpine to the flat lands of the Texas panhandle.

    Baker, Oregon to Jackson, Wyoming (525 miles)

    Via Challis this is a very long trip - about the limit of what is
    viable in one day. Using the Interstate for the majority of the trip
    would probably make it much more acceptable in terms of journey time.

    Bishop, California to St George, Utah (430 miles)

    Via US395 South to Big Pine, over the mountains via a fairly slow back
    road to US95, south to Las Vegas, then I-15 North to St George. A long
    trip.

    Craig, Colorado to Jackson, Wyoming (340 miles)

    A fairly long trip. Rock Springs is a good place to stop for lunch.

    Flagstaff, Arizona to Las Vegas, Nevada (246 miles)

    An easy trip.

    Flagstaff, Arizona to Los Angeles, California (467 miles)

    Los Angeles, California to St George, Utah (410 miles)

    An easy trip, especially if you start from the east side of Los
    Angeles. Las Vegas is a convenient place to stop for lunch.

    Lordsburg, New Mexico to Tucson, Arizona (200 miles)

    A short trip, allowing time to visit both units of Saguaro National
    Park near Tucson.

    Logan, Utah to St George, Utah (383 miles)

    A fairly long trip, with some heavy traffic likely on I-15 in the Salt
    Lake City and Ogden area.

    Jackson, Wyoming to Twin Falls, Idaho (305 miles)

    A short trip.

    Golden, British Columbia to Princeton, British Columbia (250 miles)

    An easy trip.

    Grand Marais, Minnesota to Minneapolis/St Paul, Minnesota (260 miles)

    A fairly easy trip.

    Helena, Montana to Jackson, Wyoming (410 miles)

    Helena, Montana to Kalispell, Montana (234 miles)

    An easy trip.

    I see you've decided to clip my numbers without any cause, except to decieve
    anyone reading your replies.

    Here they are again:


    WIDE open for an hour, making 2900+hp, a locomotive only burns 170gallons of
    fuel.

    With that kind of power, you can pull 4000 tons (40 rail cars) at 50 MPH no
    problem. Thats 200,000 ton miles. A truck burning fuel at 5 MPG will go 850
    miles on 170 gallons. Hauling 25 tons, thats 21,250 ton miles. If the
    locomotive is operated properly it'll use less fuel, since it won't be wide
    open 100% of the time.

    Now, unless you can debunk these figures, or have a contradictory source, I
    suggest you are the one with hot air in lieu of numbers.

    Or maybe your "facts" are simply in the loo.
