Hello Train Fans
Some of you might know me as a builder of heavy equipment like cranes or
mining shovels.
Here I would like to present my first train MOC, an EMD F7 of the Australian
Mt. Newman Mining Company.
The real loco has been hauling iron ore cars for several years and is now
retired and on display at the Pilbara Railways Museum:
Although there are already lots of LEGO-built F7s, I still like the design of
that specific type. Therefore I searched for a color scheme that has not yet
been copied with LEGO bricks and that was possible to recreate with the parts
in my collection.
The model is fully capable of negotiating curves and switches. A new feature
are the step ladders on the locomotive frame in the region of the trucks
using old style windows. They swing away in curves and therefore make room
for the trucks to swing out.
More pictures can be found on my brickshelf gallery after moderation:

Welcome to trains, Beat! That’s quite a nice F7, the colour scheme is nicely
done. I like the bogies, and those windows look great for ladders.
The only downside I can see is the coupler attached to the frame, which tends to
cause problems when cornering, if the couplers on your rolling stock are
attached to the bogies.

Hi ROSCO
Thanks!

Well, the idea with the windows is what I am most proud of on my model. I had
that idea about a year ago but haven’t used it in a model since then.

I agree, you’re right about problems when attaching the couplings to the frame.
But here on my F7 both couplings are attached to the bogies. On the rear one it
works like on the official LEGO train sets while the front coupling is attached
to a five studs long Technic liftarm which itself is mounted to the bogie. The
downside here is that the opening in the front apron is too narrow to allow for
a sufficient travel of the coupling. Therefore at the front it is not possible
to haul cars. And while pushing, there’s the problem that there is a joint too
much as there are two of them. One between bogie and liftarm and the other one
between the liftarm and the coupling itself. Here I have to think about a better
solution. But I don’t want to attach the front apron to the bogie - I like it to
be on the frame.
