1. LINKS TO THE TWO VIDEOS:
- Part 1 – Recommended Method “Delay From the Front“: https://youtu.be/LMnjJLROMQc or https://vimeo.com/300117722
- Part 2 – Alternate Method “Release From the Rear“: https://youtu.be/LMSptSSnkcw or https://vimeo.com/300124648
- There are MORE links below in Para 5 “More Related Links”.
- This video #668 shows a Z-Stuff DZ-1012v Block Signal Detector and DZ-1008 Relay automatically controlling 2 O-Gauge trains on the same track (see below photo).
Two different logic methods are demonstrated:
- Part 1 of the Video demonstrates the “Delay From the Front” method — which we think is the most versatile.
- The train in front uses the “stop block” to delay a train following too closely.
- Part 2 of the video demonstrates the “Release From the Rear” method — which has a similar logic to the “Insulated Rail” method.
- The front train is “trapped” by the stop block, and depends on the train approaching from the rear to “release” it.
3. THE IMAGES:
- The next 3 images are from Part 1 of the Video — which demonstrates the “Delay From the Front” method.
- The last image Figure 3 is from Part 2 of the video — which demonstrates the “Release From the Rear” method.
- The “Delay From the Front” method is probably the most versatile method.
- If you make a small test layout, you can easily experiment with both methods.
- Note you need the DZ-1012v Detector to do the “Delay From the Front” method.
- The DZ-1011 Detector can be used ONLY for the “Release From the Rear” method.
4. PART 2 OF THE VIDEO (Alternate Method)
- The below Figure 3 is from Part 2 of the video, which shows the 2nd logic method, “Release From the Rear“.
