Shipping Delay

Orders from now until January 25 will be shipped on January 26.


UK Customers:

We are still planning another shipping special to addresses in the UK, but the date for this has been pushed back into February or March 2020. Check back on this page over the next few weeks for the details and a coupon code to be used at our checkout.

A lower shipping fee will apply as we will import your order to the UK, and ship from within the UK. That also means there will be no duty and VAT to pay on arrival.


Bulk Packaging of Kits

When placing an order with more than two of the same kit, bulk packaging will be used. This means that instead of separately packaged kits, the ordered quantity of each component will be packaged together. One or two separate components needed for all kits will be in a plastic bag or IC tube with a label or labels applied to indicate what component is included. One hardcopy of the assembly and installation instructions will be included with the order.


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.


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.
