HO Train Spiral.

HO Train Spiral.

RE: HO Train Spiral.

Interesting that they placed extra pusher engines throughout the length.

I like how the cars on the inner tracks seem to go by faster than the outer tracks... yet I know they are all traveling the same speed.

That's why passing on the inside is preferred by racers.

Noisy bugger, but then that's a lot of wheels :)

The problem with sloppy work is that the supply FAR EXCEEDS the demand

Be a heck of a DisneyWorld theme park rise entrance "moving sidewalk"

Step on, 15-30 minutes later, step off in front of the ride loading area. Sidewalk keeps going up and over to the beginning point.

Yes - You'd need a red "Stop button" for the entry point/exit point employee/attendant, but otherwise it'd be at a slow walking pace.
If nobody is in line, you walk down the moving sidewalk. If it stops in mid-route, it stops. People can keep walking to the ride instead of the parallel sidewalks they use now.

RE: HO Train Spiral.

That would be a major flange wearer!
That must've been put together with that bendy track since the normal turn sections wouldn't allow those subtle angle changes needed to nest the spirals.

Those are coal\hopper cars. You'd almost always require buried pushers. :)

If you are EVER in the area of Tehachapi California DO visit the Tehachapi Loop. It's less than a 10 minute drive off the side of the freeway. I cannot drive past that side trip ever since it's soooOOOO fascinating. You can drive right up to it, stand in the middle of it, sit above the tunnel entrances, as no one is around there ever. It's fascinatingly disorienting to have all the massive hardware moving in various directions around you. Trains come by every 15 or so minutes.

We watched a rolling oil pipeline go by once that 14 engines moving it!

May I suggest that you look into reading the short story "The Roads Must Roll", by Robert A. Hienlein, as it provides a detailed description of how you would go about building and operating such a 'transportation' scheme.

Now if we can suggest a way for a car on an inner track to push a car on an outer track, we have the seeds of an over unity scam.

...and what happens when 1 belt in the middle comes to a stop... sadeyes

Yes, Hienlein wrote an excellent one that time. As he did so many times.

RE: HO Train Spiral.

On the HO train, the multiple engines may be required to keep excessive tension in the couplers from flipping cars to the inside.

RE: HO Train Spiral.

One way I can see how this could have been done was to build a duplicate but not necessarily identical separate spiral off camera on which to assemble the train so it can enter and exit the scene without the need to use a one thousand foot long building...

My favorite Heinlein book is The Door Into Summer; the cat in the opening chapter is oddly similar to our present feline...he may not be looking for the door into summer, but he definitely doesn't like exiting the house on the windy side.

Two more sci-fi faves of mine: John D. MacDonald's "The Girl, The Gold Watch, And Everything" for its fascinating speculation on the elongation of time, and "More Than Human" by Theodore Sturgeon and Richard M. Powers for the way the whole of six supposed human miscreants becomes far greater than the sum of its parts.
