Several days ago someone asked about a railcar photo. I believe that Backwoods Miniatures is introducing a new railcar/critter. I'm not affiliated in any way, just thought someone here might be interested in it. |

I saw that on the On30 Conspiracy yahoo group. Peter said it was based on a New Zealand prototype! I'd love to see a photo of that 
It's not totally my thing but very cool non the less. |

Hi there Steve and Neil,
It was me that was asking about the GAZ Railcar....
I like the look of the "twin Schnozzer" style critter, too.
I wonder what the point of it was? I imagine that it wouldn't have had controls at both ends, although it is obviously meant to be run either way....
So, in one respect, it could just as easily built with a utility type pick-up bed behind, and still been able to function in either direction.
Still, it's interesting.
John

Hi Neil,
Aaah, TWO engines...well, that makes a difference![:-eyebrows]
The Kiwi ones are large enough to also have two sets of back-to-back controls inside the cab.
But this Backwoods Miniatures one still puzzles me.
Thanks for the clarification, and extra info.
I have added it all to my electronic scrapbook...[:-bouncy]

Quite an interesting railcar, especially the wheel arrangement. 4 wheels on one end, 6 wheels on the other. Like Andy it's too modern for my railroad, but it's cool just the same.

The best book I have on NZ Bush Trams is The Era of the Bush Tram in New Zealand by Paul Mahoney, IPL Books, Wellington, Newzealand (1998) ISBN 0-908876-80-7
It has many photos ans history of New Zealand Bust Trams ( logging lines) inclusing the famous TTT Alco 2-4-42, built in 1907, the first of the articulated logiing Mallets AFAIK, and the Price V, perhaps the last built (1943) Heiser (although a knock-off copy and not built by Heisler). There are also many photos of 'jiggers' and 'rail tractors' Both owhich would qualify as critters.
The photo above shows a rail tractor started in 1947 and finished in 1952 with twin Chevrolet engines and twelve wheel drive used as a yard shunter (switcher). The photo is from 1961, and the tractor was used to dismantle the line in 1971 when it was then scrapped.
The last tractor in use was built by the same mechanic but had only one engine, although a similar six wheel double bogey chain-drive drive-train, but with a cargo truck cab on the front end.

Hi Neil,
Now THAT is what I call a RAIL TRUCK!!!
What a beauty!!
I love the chain drive.....[:-bouncy]
I can really see that filling in a spot on my NEW logging layout....(Prospective Logging Layout, anyway)...[:-eyebrows]
Many thanks!!

It sure is John 
My layout (that is only in my head at the moment  ) will not feature logging but will DEFINITELY have a rig like that running on it |

Hi again Neil,
I have been thinking (overnight) just how to go about building that little thang in On30...
The truck cab, chassis and running gear would not present much of a problem, but that chain drive, which converts the single-drive axle to a tandem drive (serving as a simple power divider) would be a bit of a challenge.
One would have to use some scale roller chain, linked to two sets of meshing gears on the hubs.
Having achieved that, I cannot see how one would simulate the prototypical 'droop' in the chain.
This only works in 1:1 scale because of the force of gravity acting on the weight of the chain, but in 1:48, the gravity and chain weight are reduced to the degree where I reckon that all you would get would be a constant chain 'derailment'....especially when moving from forwards to reverse...
Perhaps the only way around it, as far as I can see, is to make the chain drive direct, as here...
What do you think?
John

| Good luck in finding scale chain and sprocket that looks good in ON30 and works. Many of us would be interested having some. |
