Either you have the narrowest of gauges or the guy standing between the rails (first pic) is Bigfoot himself...

Howdy Larry, welcome to Freerails (although you have been here a bit). Looks like Gn15 to me, there are several modelers here building "minimum gauge" layouts, you should fit right in. BTW-your workbench looks way too organized and clean! I have 2 workbenches and from time to time I use a Bic lighter and can of gasoline to clean up my mess.

Woodie

Hi Larry,

That's quite a grade.
May I suggest that you look at running it as an inclined plane. Like the Vivian V2 incline in Wales?

Have a look at the Vivian in action with an inclined table at
https://www.youtube.com/watch?v=naGrum5Qsnc

This is a whole lot easier than trying to bend rails vertically at top and bottom of the grade - See my effort at
https://www.youtube.com/watch?v=Zn_I3CrbBJk
I speak from experience here

You can use Kadees to shove stuff loose-coupled onto the table from straight approach tracks at top and bottom of the hill.
 
If you notch the rail top with a small round file,
the half-round dip in the railhead acts as a wheel trap and will prevent stuff moving on the table when being raised or lowered.
I used this method to stop the car moving in the lift on my "Jaxcilliest Enterprises" minimal-sized layout.





The yellow sleeper indicates where the rail head is notched.
The notch is only about 1/2 rail head depth.

The easy way to build it is as a single track powered incline rather than the 2-track balanced incline like the Vivian system,
where the loads take one table down and bring the other table back up with the empty cars.

I hope that the these thoughts are a help.

oztrainz,
The Vivian Quarry incline is the main reason I decided to do a incline instead of a vertical cage "elevator" type hoist. Your suggestion of a single platform on the incline does sound easier than trying to balance two platforms. A vertical cage type will eventually be built into a cut away view of the underground workings of my "Appetite" mine... if I live long enough.

My layout is indeed Gn15.  The first picture was taken on my HO scale urban switching layout.

G'day Larry,
Some additional thoughts,
If you notice the attachment point for the cable on the uphill side of the Vivian incline plane cars, they are below rail height level This means that at the top of the hill the haulage cable is actually below rail level. This allows you to get the rope path away from the tracks to the winch at the top of the hill. Build in a channel under the track and a vertically mounted pulley to kick the haulage rope perpendicular to the haulage direction and away from the track.

With a "suitably heavy" incline plane car you will always have tension on the haulage rope. So the car should track well on the incline plane.

Operating the haulage is where the fun will start. At the bottom of the hill it is obvious that you have arrived when the incline car bumps up in its pit at the end of its run and the rope will show slack. The real operational problem is at the top of the hill because the you can't easily see when you have arrived.

Some suggestions for your consideration -
1 - build in a spring between the haulage cable and the incline car and listen for the sound of the haulage motor loading up when the incline car arrives at the stops at the top of the hill
2 - position a microswitch at the top of the hill such that the limit arm trips the the power to the winch motor when the incline car has arrived. For a simple DC winch motor,If you wire in a diode a diode in series with the limit, you can drive in until the limit trip, but you can drive out back down the hill even in the limit is tripped.
3 - attach a magnet under the upper cross member of the incline car and use a reed switch the sense the incoming incline car. The same diode trick will work as in #2.

Hopefully that should give you some more food for thought,

oztrain,
This info does help. Since I am not well versed in electronics, when the time comes, I may need help getting my incline to work properly.

I may be the only person on the planet who does not know this... why is Australia often referred to as "OZ"?

Larry

That figure is a Bachmann "Big Hauler" semi scale guy. I should position him so the over size feet don't show.

No, just exploit the funny side of it!.

No worries, We'll sort it when the time arrives. The electrickery here is very basic - a DC power source, a sensing switch and a diode between the power source and your DC winch motor. You have a 50/50 chance of getting the diode right first time. :bg:

Because Australia is usually pronounced down her as OZ-STRAY-LI-YA and us being the lazy so-and-so"s we we are, we shorten our words in the local dialect of "STRINE" (shortened from "Australian")

So
afternoon becomes "arvo"
television becomes "telly" or "TeeV"
telephone becomes "fone"
"She'll be right" (not a problem) becomes "shill-bee" and so
Australia becomes contracted to "Oz"

It has nothing to do with a certain wizard and yellow brick road. But we do live in the best pace on this planet, but that's a well kept state secret :P

We also tend to move our mouths the minimum amount possible when talking - it helps to keep the bush flies out. They're usually that numerous that they'll pick you up and carry you away. Then there's the sharks, crocodiles, spiders, snakes and bunyips...

And if you believe all that, then I've got a house just up the road a bit with funny sails on top I can sell you ;)
