Central Arizona Chapter Modules



To make a modular layout work, standards are necessary so that abutting modules will have track and catenary alignged, eleectrical connections matched, etc. We have chosen to use the ETE Southern California Chapter be our guide. The exception to this is to use Molex electrical connections between modules to reduce the costs. For detailed information, see Module Wiring. A few "bridging" cables to match our connectors with SoCal's will be made up. Other than that, the overall standard is based on the national ETE HO module standard. For information on the the Molex connectors with pinouts, and another take on module design see Andy Hohl's Module Design document. The original corner modules were implemented with a track "gap" at the end of the modules. In order to standardize our modules, this gap had to be elimiinated. Here are instructions for extending the track to the module end.

October 2008

We have constructed four corner modules which are the property of the Chapter. With these, we can put together a continuously running layout, or by removing one or more corners, assemble a point to point layout.

To make sure the modules align properly, we have a metal template we purchased from the SoCal Chapter.

Work on scenery for one of the corner modules. Kent Taylor has contributed the Kibri Falkenstein which was started by his dad, Sam. Kent has been working to complete the model and fit it onto the Sam Taylor Memorial Module. The team has been working on creating mountains from foam, and building other strutures.


October 2010


Tim and Karen Johnson provided scenery for one of the corner modules which
includes mountains and a waterfall. The mountains are constructed of
insullating foam boards. These were hot glued together, then cut with a hot wire
to the desired shapes. Later, a plaster-like substance called Foam CoatTM
was applied, and rock castings were added while the Foam Coat was still wet.

The waterfall was made from Woodland Scenics Realistic WaterTM
then Woodland Scenics Water EffectsTM.  Once the Water Effects
had set, white paint was dry brushed over it so simulate falling

John Leipisc took our last unseniced corner module, and added
structures from his retired German layout. John installed lights in
the buildings to add night interest.



Progress on straight modules can be found here.
