On Tour pt II; wandering the back blocks

The most interesting bit of any preservation site (or workshop) is not whats restored, but what lurks out in the back paddock. At one Hutt workshops open day many years ago we wandered off under a bit of yellow tape (if you want to stop us it will have to be a minefield and machine gun towers) and made many discovery's, including possibly 2 ex WMR 4 wheeled wagon chassis. At Easter it wasn't quite so bad ( i can't explicitly remember seeing any keep out signs, though there was one about a security firm) but it does feel odd just wandering rows of old wagons and locos. I'd just like to apologise to Steam Inc for technically trespassing...

Anyway, among other things I was hoping to get some pictures of Ka 945, but since the shed wasn't open, I had a look round the site, and struck gold. You see the biggest problem when getting shots for modeling is that there is often lots of stuff that's in the way. However if someone has already striped things down, the problem goes away.


Leading or trailing driver, possibly for a Ja.

Take the tender out of the way, and voila, the bogie is exposed.


I can now finally work out just how the whole thing actually goes together, which 2D paper plans just done explain very well.

Want to see the cross head guide bars and valve gear hangers? just take all those annoying rods off. Why not remove the cylinders as well while you are at it?


A surprise for me in that the guide bars are not connected to the cylinders, and also note how far the main drivers crankpin sticks out from the wheel.

And we may as well get a shot looking the other way as well.

What do the front frames look like behind that metalwork at the front? A bit hacked around a bit, buts still visible.

Finally, there was some discussion on the standards thread at Nz120.org the other day about the possibility of having a dead scale wheel standard. as you can see from this stack the flanges are very small (which back up my measurements on local wagons)

Reasonably useless info: Those driving wheels are more likely for a K, having 12 spokes, although the balance weight looks a bit light, more like an Ab's. Ka's have 14 spokes and J/Ja 15 spokes iirc :D (Unless they are not even 4'6" diameter.... they do have a Wf floating around in stripped-down condition, might be the 3'9"-12 spoke wheels for that?)

According to the North yard catalog its a K/Ka with 12 spokes (J's had 14 and the G's had 15). The Ab's had completely different balance weights. and it definately wasn't a 3'9" driver.

Always an interesting playground. Hope you had your notebook, pencil and tape measure as well as your camera.

Hmm, had everything in the last sentence after 'as well as'.
I don't tend to measure stuff too much after being laughed at (by a finescaler of all people ) measuring up Dc and Df cabs at a Hutt open day many years ago.

I just discovered something and I remembered this thread... I was looking through one of my books and in more than one photo taken in the fifties and sixties Ka 945 definitely has 12 spokes and it's paired with 948 which has 14.
All I can presume is that 945 was the first to be built and continued with the K's 12 spokes...
