The Rise and Fall of Tarnation

Construction Begins in Earnest on the Oil Drilling Module, but then Stalls because the Fates had Different Plans!

The big layout of the Southern California Traction Club is a magnificent layout with its City quarter, Suburban quarter, Industrial quarter, and Country quarter. Naturally I want to build some modules for the layout too. So I designed a few, then decided to start in on this one first for the Industrial quarter.



The Tarnation Supply Co. warehouse was the first structure that I built for the module. Its location can be seen on the plan and historical photo.

Then construction began on the module:

The module was built to regular HO modular standards: 1x3s with 2'x4' Homasote.

Cork roadbed glued and pinned into place.

The turnout was located first since its placement is critical having to fit between tanks and avoiding having its frog in the road crossing.

SCTC club member George Jones rasping the cork so as to bring the siding track below grade.

It is prototypical practice to have the sidings below grade. One of the reasons is so that cars sitting on the siding won't accidentally roll onto the mainline.

After the flex track was installed, the next step was to locate the main road. Thin strips of wood (paint stirrers) were used as forms for the road. I then mixed approximately a 50/50 mix of sifted gravel and Durhams water putty and spread it into the form.

After the mixture had set up a bit but was still soft, I used a vehicle to imprint some ruts in the road.

A small glimpse of what could have been. 

Here is a test shot I took to see how things were looking. But that was as far as work ever progressed on the module. The module has become a victim of progress.

The City Quarter of the Southern California Traction Club by far attracts the most attention and comments. Visitors are always crowded around the City marveling at the cars navigating through the steep canyons of the tall buildings. It was decided to extract the City Quarter from the main layout and expand on it making it a layout all in itself. It has been exhibited at a few shows now with great success. I'll explain more in a future post, but its proven to have been a very good direction for the club to grow.

So I don't know what the future of the module is. Besides the club moving into a new direction, there are exciting new projects in the works that have now captured my imagination and enthusiasm.

Too bad. This module would have been spectacular. Yes sir. It would have been spectacular.

Wonderful World of Color

Painting the Streets and Sidewalks
 I've been staring at plywood and plaster for so long that even the new concrete coloring looks exciting!
 I grabbed some buildings and posed this little scene. Two of the streets on the layout represent the pre-paved era of streets. So they were painted Floquil Earth.

 But for the most part the rest of the layout is painted Floquil Concrete. And of course Floquil came out with "Aged Concrete" right after I painted it! But it doesn't really matter anyway because...

Another case of "if I were to do it again". Because if I were to do it again, I would have used Durhams Water Putty tinted with concrete coloring. In the photo above the effects of track cleaning and chipping on painted plaster can be seen. Bright white plaster peaking through. Tinted water putty would fair much better.
You guys are so lucky to be learning from my mistakes. Yes sir! Your so lucky!

Paving the Way

Pouring the Streets and Sidewalks. 

Extensive testing of the track is essential before its covered with street paving. Especially that intersection. Making revisions to the track would be most difficult when its buried in plaster. Plus its fun to just run the cars around too!

It seems logical to me to pour the sidewalks first. I used angle stock that was the thickness I wanted the sidewalks to be. Where the sidewalks curve at the corners I cut slots in the angle stock so that it could bend (sorry about the dark photo). Then the angle stock is spiked down to create a trough to pour the plaster into. 

I used lightweight hydrocal, but if I was to do it again, I would use Durhams water putty. 
Originally designed for DC operation, the track is cut into electrical blocks. In the photo above you can see where the wires come up from under the layout and soldered onto each rail of each block. That also has to be tested for electrical continuity before being buried in the plaster.
 Once the sidewalks were in and the track passed inspection, I started in on the streets. Stripwood equal to the height of the rails were glued against the sidewalks (where the gutter would be). Then plaster could be be poured in between. The stripwood and rail would be used as a guide for a paint scraper to smooth out the plaster. I stuffed thick string into the flangeways to keep the plaster out, but I think I could have just masked if off with tape.

Interestingly, all the spikes rusted and soaked through the plaster. But I don't think the strength of the spikes were compromised. Besides, everything is now held firmly in place by the plaster. Derailments should be nonexistent since the whole layout is basically a rerailer!

Finally I sanded down the all the streets and sidewalks with a block sander to make it all nice and smooth. I don't want any pour marks showing. I also scribed expansion joints in the sidewalks before the plaster got too hard.

I can't get over how different the layout looks now. It's all looks so neat and tidy. Now I have got to get some paint on it. Right now it looks like a winter wonderland. Yes sir! It looks like a downright winter wonderland!
