1. LINKS TO THE TWO VIDEOS:

2. SUMMARY:

  • 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:

Note: CLICKING ON any of the below images, should open them LARGER.

 

 

  • 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.

Opinions:

  • 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“.
