Lots of detail still to do. Here's most of the instrument panel:

The X-20 will be a Poser figure. The rudders, elevons, and skid landing gear will operate realistically. Here's an early render:

The Wind Train is now in the Marketplace:

The Wind Train uses a historically accurate broad gauge track developed by Isambard Kingdom Brunel in the 1800s. The gauge (or width) is seven feet vs. the standard four foot eight inch gauge. The Brunel railway is also distinguished by longitudinal running under the rails and tied together by lateral transoms with tie rods. The Brunel track looks very different from standard rail.

The Wind Train includes a set of morphing track with several kinds of roadbed.

Here's a fully-textured render of the passenger car:

And one of a 2-car train on the broad-gauge track:

Everything is pretty well finished now and into final testing and kitting.

Here's a render of the second class passenger car with the side hidden to show the interior. The seat backs flip to face rearward.

I'm still finishing some of the rigging.

The wind train is imagined but it's imagined with actual historical parts. For instance, it incorporates wood-core Mansell wheels that were designed in the 1800s. Here are two renders of the Wind Engine with one side hidden. In the second the wind rotors are lowered into the engine.

Do read them. I read the trilogy for the first time many years ago, and found they held up to my second reading this year. The first book, Souls in the Great Machine, is almost startling in tis originality. It's a very different post-apocalyptic novel depicting a society where "Dragon Librarians" hold the real power because the library, Libris, has maintained the knowledge of the past, but where disputes are settle by duels. Steam and electrical power are forbidden and Libris, has established a computer, the Calculor, that operates with human component. Through this all a mysterious "Call" periodically turns everyone into a mindless wanderer. In my opinion, the second and third books, which expand the world from Australia to North America and provide more of a back story, are not quite as good but I was intrigued by the characters and carried along nicely.

Low quality render of partially textured wind engine: The engine has a working heliograph on the roof platform for signaling. There is also a set of operating wind instruments.

While the engine is described as complex with masts, booms, cables, the passenger cars are simple. Here are a couple of early toon renders:

The LK is now available in the Marketplace: There is also an associated freebie of the Soyuz 7K-LOK Lunar Orbital Spacecraft, mentioned above, released under and compliant with the Creative Commons Attribution-Share Alike 4.0 International license, based on the original mesh created by Fac-tory-o, available as a STL file in the Wikimedia Commons, licensed under the same license.

The LK lander like the Apollo LM, which was similarly cramped with similar arrangements and carried two astronauts, was used only to descend to and return from the moon. Photos of one mock-up show a sort of bench, but those of engineering versions do not. The LK lander was accompanied to the moon by the Soyuz 7-LOK, which was equivalent to the Apollo Command/Service Module and had more room as well as couches for two cosmonauts. Of course during most of the flight the cosmonauts would be weightless.

I've submitted the Russian LK Manned Lunar Lander to the Marketplace. Here's one of my test renders using a DAZ lunar moonscape:

The figure is essentially finished. Now on to the packaging and images for the market. Here's a view of the interior:

Nearly finished. Just some clean-up needed:
