  1. Your right Metsfan.The cosmos have been doing this for over 30 years.The M8s though are a much heavier piece of equipment and requires more power.As we speak,metro-north are working around the clock to update the electrical distribution system to the cantenary,once it was theorized that the M8`s had the potential to blow out substations due to its heavy power consumption similar to what the M7`s were doing.

     

    I know (NJT) had to do some major backend work to switch the :me: from DC to AC, not just more juice for the new equipment, but AC, and longer trains too.

  2. For MU that have been in service non stop since who knows when (before alll most all of us on here were born), through the hell years of railroads, over 2 voltages and line frequency of AC, plus 3rd rail DC, the cosmos are in remarkable shape, and have been the unglamorous workhorse alongside the FL9's, through blizzards, wars, how many presidents... They got the job done & still do. Will be sad when they go, i just hope the M8 is a worthy replacement in real world day to day operation.

  3. In my town i have seen these on the road, usually on the move:

     

    Gas station fuel storage tanks.

    Wind turbine tower sections.

    Wind turbine blades.

    Wind turbine nacelle.

    Everline railcars (5 total spotted).

    Transformers for a tier 1 substation.

    Bank vaults.

    House sections.

    Trailers for mobile home parks including FEMA trailers.

    Mobile cranes.

    Satellites.

    Missile parts.

    Rocket booster segments.

    Trees.

    Tree spade (the huge 6+ blade type).

    Large steel truss segments.

    Large concrete pieces, including beams, pipes, and septic tanks.

     

     

    In the sky i have seen galaxy and starlifter and hercules transports, more than once a piece. I have seen a sky crane helicopter.

  4. I have seen bomb cars for the Everline service in south korea parked over several nights near the i95 interchange.

    I just noticed they use dual bottom contact 3rd rail... WEIRD!

  5. Oh i know, i was saying external lenses that attach are 99% of the time for SLR systems. Telephoto lenses attach to the camera body as with the other lens types in the SLR systems.

     

    All in one or point and shoot cameras rarely have the ability to attach things on as far as optics, though some models have a telephoto converter kit that you screw on, but is a converter not a separate whole lens package. :P

     

     

    For SLR:

  6. So, optics. Coated, uncoated, fixed zoom, ultra zoom, what does it all mean?

     

    Basically you need a good set of glass (optics) to get the light from out in the world, to the image capture mechanism, be it film or some sort of solid state sensor. Coated optics have a coating to ensure good transmission, reduce reflection, and protect the surface from dust etc. Some coatings are hydro-phobic, meaning they repel moisture, keeping condensation from ruining your shot. Some cameras have a fixed zoom, meaning you control only the aperture, focus, and exposure, some fixed zoom cameras are automatic, such asa Polaroid type camera, meaning you only have one button, the shutter release. some cameras have an ultra or long zoom capability, meaning you can see things far away, all most like a telescope, without adding a telephoto lens. Telephoto lenses are attachments for SLR cameras for the most part, however some non SLR cameras have conversion kits.

     

    Built-in zoom will depend a lot on your camera's size, for instance, don't expect a 3 8th inch thick camera to get 15x zoom, there really isn't enough space to store the optics when folded (closed). There are a very few exceptions to this rule, as folded optics, and stacked optics technology has advanced quite a bit in the last few years.

     

    An example: http://www.olympusamerica.com/cpg_section/product.asp?product=1449 10x zoom in a pretty compact form factor.

     

    SLR zoom will depend on many factors, including construction, purpose, and settings. Some lenses in some configurations are more limited than others, because of focal range and exposure, but in general clip-on/screw in lenses are far more flexible, and expensive (some in many instances may cost more than the camera body) than built in.

     

    It is a good idea to when looking for a camera with good zoom capability, put it second to image stabilization, weight, and price, unless zoom is your primary concern and you all ready know about the image quality to be expected etc.

     

    Next section will focus on batteries and power sources.

  7. The cables are for head end power, door control, PEI, data, and air for the brakes.

     

    All comet 5 trailers in lead position (hooked to locomotive) look like this when uncoupled. A GP40FH-2 was hooked to this train from bay head, but was unhooked for fueling, the lights are running on battery power.

     

    The panel with buttons is for door control. Comet 5 have a separate door for low and high platforming on the end doors, and it can open either side of the middle door separately. Combinations of button pushing gives you the desired door opening results, including which to keep closed for the whole trip. There is also a cut-off switch for each door that can enable or disable using a key, this is usually done in order to keep the non-platform side from opening, however in yards and deadheads it can be disabled for convenience.
