Supertrain Clips

this is a great rail technology, a wide body train, i wander if they would make this a reality in the world?

Possibly not, jet travel has replaced train travel in the world.

it did in the 1960s but Bullet Trains in england parris, Japan, and Germany replace air travel.

California is going to build a high speed rail between San Francisco and L.A. This would be the way to go.
Or better yet - between L.A. and Las Vegas.
A few years ago the Supertrain model was sold through an ad in Model Railroader and has not been heard of since.

Was this pre-ebay? Any idea what it went for?

Yes, several years before Ebay. I think the owner wanted $25,000. I don't know that there was any follow-up in MR because it was an ad, not an article.

they are planning to start on the construction of the desert Xpress high speed in March of 2010, I hard that the CAHSR would start on their construction in 2012.

Heh, I didn't make the music....
The music is theTheme from 'Supertrain' that I found online and embeded into the video before posting it to here.
Thanks in part to Micro$oft Movie Maker.

Gotta dig the the suggestion in the elements of the theme.
The opening bass-line evokes images of madly-pounding pistons, and the horns suggest the dawning of a new era before taking a "charging" melody.
Then the violins give notion of a superhero-esque something coming down to earth, before merely accompanying the horns to represent a train whistle.
Then at the conclusion of it, the synths make a sound of suggestive of something whooshing-by at high speeds.
Overall, a well thought-out work!

Well, it's made by Microsoft so both names are valid.

Does it really matter ?
