Making progress. Rekindled this vintage American Type by Pola, sturdy old beast, period correct. The diamond stack was an ash catcher for wood that was burned where wood was then plentiful. In terms of BTU's it would seem that compared to coal it would have been inferior.
Trying to get the elevated tier sub road bed level and sturdy was a trick. It had to be three inches above the lower gradient to allow clearance, and the Styrofoam packing I attempted to utilize ended up being impossible to carve to the precise level, and generally difficult to work with. Bagging the whole lot for something else seemed to be the next best option, when I spied these cardboard mailing tubes whilst waiting in line at the post office. Three by three inches, they were perfect, and once installed the train ran splendidly.
Initially, I thought I would have three, perhaps four, trestles to span the lower tier. When I started scratch building the bents, it became quickly evident that the overall gap, created by the curvature above, would be far in excess of what would look believable. Those old trestles were pretty close together, and it would have been a awkward thirty or forty foot gap crossing the radius below. Thus, using the same Balsa I am now scratching up seven timber tunnel portals, instead. Necessity being the mother of invention.
The final step in the puzzle was ground cover. Gluing the right shade of sand over the entire thing, over white plaster, would be a logistical nightmare. Living in the desert, there is no shortage of sand, but it is heavy and would need to be colorized to get the golden shade of sandy earth desired. Then, trying to apply the ground cover to the many vertical faces of Mormon's Gulch would require slopping on gallons of glue water, tipping the layout to various ninety degree angles, threatening to warp and damage everything.
Upon someone else's suggestion, I had used textured spray paint for simulated ballast on Henley, with reasonably good result. Spreading sand and glue upon rails and switches is something I've tried, and not enjoyed, at all, particularly if something had to be moved or adjusted. This tan colored texture spray paint ought to give a reasonably acceptable facsimile of the golden tan of the Utah desertscape.
Ultimately, Mormon's Gulch will slide neatly into the back of the hatchback, along with the subway layout, for transportation to model train
shows. It's always fun, or used to be, to show your stuff and chat with other model railheads.
