Signal Animator System Response

A new application note about Signal Animator System Response has been added to the documentation for the Signal Animator. This document describes, input by input, what each indication is displayed. It is designed for those using the SGA to help understand what happens when input states change in order to test out wiring after installation, and any later fault finding that may be needed.


Basics of Signalling Article Now Available

A new article titled The Whys and Hows of Railway Signalling is now available. This article covers an overview of signalling: from the basics of what its purpose is, a brief history of how it has developed, and where signals should be placed. The article is available on our Tips & Tricks page.


Creating a Signal Plan Article Coming Soon

With recent work involved with one of our customers using our Signal Animator in ABS mode to signal his layout, the importance of creating a signal plan became apparent. A signal plan puts down on paper where signals are located and summarises what indications are needded for each signal. This permits confirming the SGA can support the needed indications, and identifies how the SGA interfaces with other components. Out of this, a wiring diagram can be developed to assist in making the necessary connections, and provides a list of system responses to permit testing that a signal will display the correct indication for each situation. A signal plan also makes it easier to see if your numbering scheme for signals makes sense.

This article should be available in the next few months.


Evolution of a Signalling System

Our article on the evolution of a Signalling System has been updated to outline the latest developments.

This article describes a currently working system that is not practical to market in its current design. The article describes its features and outlines the shortfalls that make is unmarketable. Then it outlines current plans to redevelop the system so that it can be sold as a product along with other items we offer.

If you are interested in signalling for your model railroad, or just curious, we encourage you to take a look at this article. There is an email link at the bottom for any questions or feedback.




We have added accessory items to our products page. This will include items for use with our products such as IC sockets, header plugs, spacers, and jumpers.


Traverser Power Supplies:

We now have a power supply suitable for the Traverser. It is a "wall wart" type power supply that provides 12 VAC at up to 750 mA, from a 120 VAC outlet (Canada and USA). The price is $8.99 on its own, but will only add $7 to a Traverser/QOD combo. See The Traverser product page for details.


Grade Crossing Bell Sound:

Our Grade Crossing Controller (GCC) implements the logic needed to operate a grade crossing, including the flashing lights. It is still necessary to have actual signal lights it will control, and if one wants an operating gate, that too must be built separately. Then there is the question of sound: a bell that sounds when the crossing is active is the ultimate bell and whistle for the layout.

There are sound modules available on the market that are reasonably priced. The HQ Series Sound Effects Module by ITT Products is one device that we have tested with the GCC. All that is needed to interface the two together is a resistor and a transistor. Take a look at our Documentation Page to see the new Application Note.
