A four wheel car handles vertical curves in the track just fine, even with rigid axles. The rear axle IS rigid but the front can rock side to side (springs dampen this motion) which keeps all the wheels on the rails in places where the track may be out of level, side to side.

I test-ran the frame extensively (with crew-man aboard) to confirm things were OK with this design. Based on these tests, I moved the draw-bar connection back to the end of the main body, relieving side-stress on tight curves.

I also set the wheels-axles up so that one wheel can turn independent of the other. This has much less drag on those tight curves.

Entry/exit will be easy. The cupola sides will hinge at the top and swing upward; the side door will slide open to the rear. This combination will yield a quite tall doorway.

Hard to tell in this picture but the top frame (above sliding doorway) has been removed. This part will be reattached to the bottom of the cupola side.

Prototype "bobbers" have their wheels located near the ends of the car. This adds stability and is fine if track radius is broad enough.
Again, our radius is really much too sharp for these large trains. We've often had to mimic LGB to make things work. Long fixed wheelbases are constantly seeking a place to climb the outside rail and if you CAN keep things on the track (enough weight) this arrangement makes for much wear of flanges and/or rail. (Our rail is aluminum and quite susceptible to wear.)

Ergo: 308 has a very short wheelbase.

Seems very well thought-out.

Thanks Ray,
I sure hope so!

Now, how about a bit of Photoshop MAGIC?
This was shot on our layout but I removed all the background clutter for the open look we can never have there and changed to B&W to "move back in time".

I call this "Working the lumber yard".

I worked from this photo.
To fully enjoy model railroading one must possess the child-like ability to PRETEND.

Dennis, THANK YOU and a happy and blessed New Year to you and to all!

2014 was a very good year for BLRY. We survived a reinvention and still made a lot of progress.

See below: Where we were a year ago......

My method of design is a hands-on approach. What I mean is I start with concept drawings, then move to a full sized mock-up and refine the design as I build. The project, hopefully, ends up a much improved version of the original concept.

Here is an example. This is a recent photo of the caboose under construction.
