Can someone please pass on the wheel size and axle spacing on the Aristo-craft center cab diesel ? 
I wish to model a loco from Australia called the 'Harman' which was built in Port Melbourne Australia (1927) for the Tyers Valley Tramway in Erica Victoria Australia.
It was a complete flop for the job so they bought a Climax in the end, Oh well !
The trucks look like they may do with modification or rebuild of the side frames.


Looks a bit plain fugly but that's they way I like em !
It was a 2'6er and had a small piston on each side of the trucks to an internal reduction gear centered below then reduction chains to each axle.
Axle spacing on the prototype is about 3'6" so I need about 53mm which is way small but close enough will do.
A published plan is available in 'Narrow Gauge Downunder' mag Oct 2007 if anyone is interested.

Any help would be much appreciated.

Thanks Dennis

That is about 60mm which is about 12% larger than prototype which I guessed it would but that is close enough. 
As for the wheels they are about right !

Excuse me for the metrification, they changed half way through my schooling here in Australia as they did with the money too.
I still use both, depending on what I am measuring.
Imperial is better suited to human size things for me.

I will order one of those Aristo pups and rip it's legs off ! /DesktopModules/NTForums/themes/mls/emoticons/shocked.gif

 A close up of the Harman bogie.

A bit wierd to make out but the springs are removed and the truck displaced to the right with the cradled bar that the springs sit on missing. /DesktopModules/NTForums/themes/mls/emoticons/crying.gif

Trainworld have the (plain) powered trucks (pair) listed for under $100.
I will build the truck sides myself to resemble the Harman's.  

Looks like an easy project because:-

Can use basic motor blocks.
There are no rods or mechanisms.
The Harman has a straight boiler.
The locos body is simple and boxy.
There is only a single dome and stack.
Any colour you want as long as it's black.
