Adding TCS wow sound decoder to Bachmann Heavy Mtn

After receiving my package from Tonys Train exchange, with my DCC system and sound decoder etc,  I started the installation in the Vanderbilt tender which has limited room in width to install a round speaker. So here are some shots following Erik from Tonys Train Exchange advice , using 2 new mini speakers.

Amazingly small TCS Wow sound decoder to install in tender

This decoder has many choices of bells, whistles, engine types, all manner of mechanical injectors, pumps, generators, brake squeal, air release as well as light control and great control of the running engine including very slow speed right out of the box.

Holes need to be drilled through the tender bottom to allow the sound exit.

New batch of rocks

Rocks cast in Hydrocal, from many different molds from several manufacturers, and from my own mold shown in last post from a previous casting. Most will be used in the mountain area around the logging branch.

I use a lot of different rock molds from various manufacturers, including Woodland Scenics, but I just came across a rock mold I made a while ago from a fine grained piece of rock  found in the garden.

Latex rock mold

Nice detail in the rock and think the cast from it is going to make a nice outcropping in the river valley. Just needs some coloring and weathering plus some small evidence of vegetation.

Removable mountain

 

Starting to get whole logging area working, and I needed a mountainous area for logging but it should be removable because it would be over several fairly long track tunnel sections. I thought a base of foamcore would work, be light but strong enough with a structural frame above, making it more ridgid.

Thinking about how I would do this, I decided to try the new shaper sheet material, but even though Woodland Scenics says it needs no under support, I wanted to visually rough in the mountain and thought a hot glued cardboard strip web would also give it more strength, since it would be movable. Actually I do not think it will have to be moved all that much because even with a derailment under the tunnel, you can pop up inside the mountain enough to retrieve a car or engine.

The Shaper Sheet material shown is interesting as it has a very heavy foil backing with a fabric adhered to the foil, that mechanically bonds with applied plaster. Woodland Scenics has a Plaster made for it which I believe is lightweight Hydrocal with a retarder to slow the hardening so there is time to work a soupy mix, and get it into all the crevices.

Timber Tunnel and track access panel

Back to the timber tunnel project:

Tunnel with cover

Here is the tunnel and the piece of Woodland Scenics Shaper Sheet material. I thought I would try it to produce an removable access panel. The Material is a bendable heavy foil backing with a fabric (the white to the left of the tunnel) bonded to the foil. This is then coated with thinned plaster. Woodland Scenics sell a special plaster for this that has a longer working time, so you can coat the whole sheet before it starts to set up.

Removing Access cover

The plaster has not yet been added in these photos, but you can see that it still holds it’s shape pretty well, and will get much stiffer and stronger once the plaster and other scenic material has been applied.

Showing Track that is covered

Here you can see the track that the panel will cover, giving access to an area of a long tunnel in case of derailment. Edges of the panel will have bushes, small rock areas etc to hide the edges of the panel. I will enter a post in the near future when I complete this section with scenery, ballast and cliff faces.
