Circuits4Tracks Made in Ontario

Circuits4Tracks has been approved for the Ontario Made program, presented by the Canadian Manufacturers & Exporters. This allows us to use the logo seen to the right on our products registered with the program. All of our products are designed and developed in Ontario, as well as all final assembly (and testing of ready-to-use units).

More information on this will be coming soon.


Interested in Expirementing with Occupancy Detection?

While our Quad Occupancy Detector is one of the lowest-cost way to detect occupancy, we have a limited-time special for those wishing to experiment with even less initial cost, and do so without first having to assemble a kit.

We have a limited supply of fully functional "Version 2" QODs available for the low cost of $1 per detector (that's $1 for a single, $2 for double, $3 for triple, and $4 for a fully-populated QOD) plus shipping. Version 2 was the second generation of our detector that pre-dates when we initially started selling the Version 3. These were used on our own layout beginning in 2009 until a recent re-wiring project involved using DIN rail board carriers that the older detector boards do not fit (Version 2 boards are 3" square, while current boards are 2.75" square).

These detectors have the same specifications as our Version 3 QOD. Like the Version 3, these only have a 1x6 header for the outputs, though some are straight and some are right-angle (like the one in the photo to the right). Also like the Version 3, they have a 3 amp maximum block current.

We will have a full count of available units shortly, but in the meantime you can send us an email for details on what is available and how to order them. Regular shipping rates apply, but free drop-off is available in parts of the GTA.

NOTE: These detectors are not ROHS compliant.


COVID-19 Issues:

We are pleased to say that it is business as usual for us in these unusual times. One of the benefits of being a cottage industry is that shelter-in-place provides more time. We have a good inventory of components, so if our site does not indicate there are units or kits that are ready-to-ship, these can be shipped within one day in most cases.

Our Signal Animator is the only product that is temporarily unavailable as we have run out of circuit boards.

Please note, shipping may be a little slower than usual due to limitations of the postal system under current conditions. For customers outside of Canada, it is likely that your country's customs clearing will be slower than usual as well. Several orders we have shipped spent the most time being cleared on entry to the destination country. If your order uses tracked shipping, you will be able to keep track of where it is at while it is on its way.

We continue to develop the new signalling system and hope to have some updated information on its evolution on this site soon.

Stay safe, and keep on railroading!


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.



Niagara Frontier Region Convention
We expect to be doing a clinic on Signalling and Block Detection.
However, this event has been postponed until an undetermined date.
Please check back to see this information as it is updated.
