Signaling your layout with DCC for control/operations

A discussion of the fundamental processes and steps necessary to design and build/install a successful layout railroad signaling system - basic to advanced.



Presentation will include the methods and hardware variations (options) needed to install and operate various prototype signaling systems. Included will be our experience and lessons learned having done/assisted/advised on several layouts in the Pacific Northwest and west coast. Time will be allotted for questions and answers during and following the presentation.

Designing a signaling system with cpNode (CMRI on Arduino)

Chuck and Seth will describe their experiences designing and implementing Model Railroad Signaling Systems and how they have used the cpNode system they developed, to streamline the process.
They will discuss power distribution and detection topologies, setting up signal locations, dividing the layout into blocks, cabling, cost optimization strategies and much more.

Phones for Ops - updated!

Clinician: 

Seth Neumann will review the requirements for an operations communications system and take you through the design process and show you how to implement a reliable telephone system for dispatching any era from the 1870s through the 1980s using your choice of inexpensive telephones or period equipment. The emphasis this year is on low cost electronic replacements for hard-to-find vintage parts.

Adventures in Dead Railing the HO/HOn3 Donner Summit

Clinician: 

I have been a member of the Dead Rail Society for several years, a group in San Diego area devoted to running trains by wireless DCC and battery power. The availability of lithium-polymer batteries and smaller radios has made this method of running trains, common for many years in larger scales, available in the smaller scales. I recently converted my Donner Summit HO/HOn3 layout completely to Dead Rail and removed all the track feeders so there is no power on the rails. In this clinic I will discuss the pros and cons of this move and how it has effected operations both positively and negatively. I will also discuss the design and construction of the layout which is based on an HO version of the Southern Pacific and an HOn3 representation of the Nevada County Narrow Gauge Railroad. Disclaimer: I am the owner of Tam Valley Depot which manufactures and sells the DRS1 radio system discussed in the clinic.

Controlling 280 Turnout Servos Using Fascia Mounted Panels

Clinician: 

This clinic presents one solution to controlling a large amount of turnouts and crossovers using mounted servos. The servos are controlled using pushbuttons located on fascia mounted panels. The electronics needed to drive the servos and to provide led lighted track routing on the panels will be clearly explained and demonstrated. There will be a step by step procedure that shows how to map the turnouts from a sample branch line track plan to the panel push button controls and to all the electronics and logic needed for successful operation.

Basic electronics for model railroads

Clinician: 

Over the past 20 years, model railroading has moved into the electronic age, with the widespread use of DCC, computer control, and signaling. Learn the basics of electronic theory, what all the different components are and what they are used for. Some of the things that will be covered are the wire size for the layout, the different formulas that you will need (how to figure out what size resister to use for dropping the voltage to the headlight), and the tools that you will need to troubleshoot your railroad.

Modeling with sound: Scale model animation for model railroading

Clinician: 

The use of sound in model railroading goes beyond DCC sound decoders in locos and cars. DCC sound decoders can also be customized for other models. Creating background layout sound has become easier to create, customize, and implement too. This clinic will explore your options for adding sound to your models and layouts, using different approaches, techniques, sources, and players. Come and find out how you can make some new joyful noise!

Modeling with movement: Scale model animation for model railroading

Clinician: 

Making things move is virtually synonymous with model railroading. But making things move realistically can go way beyond movement on rails. This clinic will review different mechanisms and means to add movement to scenes, buildings, cars and models to add visible "life" to your layout. Small, scale, smooth mechanisms can be built at low cost using a variety of techniques. Come see how you can move your world!

Modeling with light: Scale model animation for model railroading

Clinician: 

Layout lighting was once relegated to headlights, coaches and "whole house" lights. The availability of bright, tiny, light emitting diodes (LEDs) and other new technology opens opportunities for modelers that go beyond the norm. This clinic will look into combining these LEDs with "new" materials and electronic control expanding modeling options even more. These dynamic lighting techniques can enliven scenes and layouts in a big way. Come and find out how to light your way!

Measure your diesel horn

Clinician: 

Part 1: This clinic shows how to measure the continuous (RMS) sound level of your Diesel Horn with a Sound Level Meter. There is a proper way to report your Meter results to others.
Part 2: Measuring the true (RMS) voltage driven by a DCC Sound Decoder into a speaker system. Then calculating the wattage of the measured (RMS) voltage based on the impedance of your speaker(s) (4, 8, 16, or 32 ohms)
