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 October 14, 2015, published by the Railway Association of Canada.
