Very cool video. I noted a couple of things which relate to another thread here on FR about a pole road loco. The wheels are more like thread spools than pulleys, check them out. And one of the wheels looked like it had a truck tire between the "flanges", probably an attempt at a "traction tire"...ya suppose? Food for thought, or modeling.

I still want to see an un-Photoshopped picture.

Narrow Gauge Railways in America
  has a chapter on various lines (in 1876)
and cites-

''FARMERS UNION RAILROAD--in Iowa, has a charter to build a road from the Mississippi river, to the Missouri river, a distance of 300 miles. At yhe end of the year, they had built 12 miles, between Liscomb and Beaman, and ''track laying is still going forward''.

Maximum grade 53 feet/mile, and this is maintained for about a mile. Sharpest curve, 4* (1432 ft radius) The rail is of hard maple wood, 3 1/2" X 6", notched into cross ties and keyed, and estimated to last four years.

Average cost of road per mile, including equipment, $5000

Equipment- one locomotive and 10 freight cars.''

The fact that this is sawn wood would indicate that a single flange on the wheel was used, which would mean that a switch would be possible (but chances are they didn't have one)

It looks dual gauge.

@tebee
Normally one can enlarge the thumbnail by clicking on it, and copy the internet address given then - it will show a larger picture in the posting. So, please...

It unfortunately the biggest version of the picture I could find on the internet - from here http://www.alexandratramway.org.au/historical_background.htm

I am still looking for a bigger version

Those are not thumbnails, but holding down (ctrl) and hitting (+) will magnify the screen view. Jose.

Jose-
When I do that, only the text gets larger.

Tebee-
Thanks for that photo and link! From what I can see, the wheels of a car taking the diverging route would have to physically jump over the straight rail at the ''frog''--but that very may be just because the pix is so small.
After having made the assertion that a pole road switch is impossible, and having been proven wrong (happens all the time), I will give you all another chance to prove me wrong--by saying that the unshown part is built like a stub switch.

Herb

Download this document.
you can enlarge the picture ( 300%) sufficiently to be sure about some details.
They used single-flanged trucks and the frog is of the kick-over type as used e. g. in the North Wales slate operations where they employed double-flanged vehicles.
Of course it is a stub switch.
Interesting to note that the straight road even is dual-gauge!
