The ability to have signals with speed indications can involve a daunting circuit if performed in hardware. Software drastically simplifies this, but requires a significant number of outputs. Add to this is the choice of signal styles: 3-colour versus searchlight and the way to wire them: common positive or negative.

We have designed a signal driver around a PIC microcontroller to get the best of both worlds. The Signal Animator does all this with the flexibility of being usable for searchlight and three-colour signals, wired common positive or negative. As a background to this design, here are some references regarding signalling:

This article describes the patterns and non-patterns in CROR signal indications. Originally appearing in the February/March 1994 issue of Rail and Transit (the newsletter of the Upper Canada Railway Society), this article has recently been updated to reflect new signal indications in the latest revision of the CROR.

This is the latest revision of the Canadian Rail Operating Rules, effective June 24, 2020, published by the Railway Association of Canada.

The Signal Animator version 1.10 is now available. There are some minor changes coming to the product.

Software

There is a new version of the software. SGAs sold since 29-Jan-2017 had version 2.00, but the current release is now 3.11, 3.12, or 3.13 (see below) which has the following changes:

Three versions of software are now available, with the difference being the default operating mode. You can always reconfigure the operating mode at any time, but if you use a particular mode, you can receive your SGAs ready to use without the need to reconfigure:

The software hex image on the SGA Documentation Page has version 3.11 available. If you have older SGAs but do not have the ability to flash the software, email us to find out if you need the update and how it can be arranged.

Circuit Board Layout

The version 1.10 SGA boards have a few layout changes. Overall dimensions and the mounting hole locations remain exactly the same. The changes are:

Circuits4Tracks only makes the electronics for signalling, we do not make the wayside signal appliances. The Signal Animator has the flexibility of being able to drive either Type D (3 separate LEDs) signals or Type SA Searchlights (using either Red/Green, or Red/Yellow/Green LEDs), wired with either common anode or common cathode.

Various manufacturers of signals exist. One option is to purchase dummy signals and add your own LEDs and a company that makes signals for HO and N scales is Pro Tech Model Parts.

Ordering multiple 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 required 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 the component. One hardcopy of the assembly and installation instructions will be included with the order. If you require individual kit packaging, you must email us in advance or at the time of ordering.
