Hello All,
What a great project!
Now, slightly…[#offtopic]…
I am a big fan of specialty flatcars; heavy-duty 6-axle, 60 ton Gunderson Well, and multi-axled and truck depressed center.
My pike is based on a coal mine branch loop.
Lots of oversized loads for the mine arrive on specialty flatcars negotiating 15-inch curves and #2 turnouts.
As I look at the 2-C+C-2 configuration of this locomotive, the first thing that comes to mind is “minimum radius.”
Just like the articulation of multi-truck flatcars, from what I can deduce from the photographs is, the truck assembly seems to be double-articulated.
From a modeler’s perspective the cab unit could be easily replicated with a Gas-Electric box cab.
Reproducing (scratch building) the truck assemblies is going to be the challenge.
From the photographs- -the leading trucks seem to articulate independently from the side frames that support the traction motors.
The center pin of the entire truck assembly is the attachment point to the cab.
If I were to model the 2-C+C-2 truck assembly I’d look at Northwest Short lines Standon drives.
Perhaps the 38-inch assembly.
Even though these are only two-axle units, a third dummy pair of wheels could be mounted inboard of the drive wheels.
InterMountain Railway Company makes HO-scale 38-inch wheels.
For the leading two-axle units, 28-inch scale wheels might provide the clearance needed for the front articulating trucks.
Using the Stanton drives- -over traditional center-mounted motor/drivetrain configuration- -allows for the area previously occupied by these components to be use
