* This AutoControls.org Video 833 shows a DCC Programmable Train Controller (aka NCE Mini-Panel) operating an Automatic Passing Siding -- using relays to control 2 non-DCC, 3-rail O-ga. Williams Chuggington locos (and later MTH docksiders, and also an MTH PCC car and Williams Peter Witt car).
The Controller uses 4 relays: 2 relays to start and stop the 2 locos, a 3rd relay to control the "diverging turnout", and a 4th relay to control the status light.
* This system uses toggle switches, to control whether both trains travel once around the loop, or both trains travel multiple laps around the loop, or to run just 1 siding only (other siding "parked"), or have one or both trains keep repeating the sequence continuously.
* The system is configured so that it can be used as a public display. It has a pushbutton out in front, labeled "Push and Release, when Status Light is Green". The 'Status Light' shows Green when the controller is Idle, and changes to Red when the controller is 'Busy' with running a sequence.
* A Z-Stuff infrared detector is used to detect when trains are entering their siding.
* Also demonstrated is a variation using NO detector ("running blind") -- by allowing extra time to be sure the train being run, has enough time to pull into its siding after its stop block is de-powered -- before the other train is started.
The Controller uses an LGB DPDT latching relay to start and stop one siding, and an Azatrax.com DPDT latching relay to start and stop the inner siding.
The Controller uses one side of an NCE 'dual relay' (2 relays in one) to control the MTH diverging" turnout, and uses the other side to control the red/green 'status light.

In this video, we'll show you EXCERPTS (small pieces) of about TEN different videos.
We'll show 3-rail O gauge demonstrations if we have them. A few will be other scales, but would work the same in O gauge.
You can refer to those videos for complete demonstrations and explanations.
Please consider if this is something you might want to get your grandkids involved with -- as it combines both very SIMPLE programming and O gauge model trains -- which we think they might find interesting.
Demonstrating a simple program might also be entertaining for elementary school kids.
Having the kids enter the program themselves, would combine both programming and trains.
They could be even given homework assignments, to repeat this programming experiment on their train at home.
