1. Overview:
- This new video (#668) shows a Z-Stuff Infrared Block Signal Detector and Relay AUTOMATICALLY controlling two 3-rail O-gauge trains on the same LIONEL O-27 track loop.
- This is probably one of the SIMPLEST methods you can use to control two non-DCC trains on the same track.
- It just requires 1 "Stop Block" to be cut in the center rail (or either rail if using 2-rail track), and then placing the detector-relay combination at the end of the block.
- Although the demos use O-gauge trains, this detector-relay combination should be able to control trains of just about ANY gauge, 3-rail or 2-rail — using AC, DC, or DCC track power.
Maximum Current: (updated 12/24/23)
- Note the RELAY used to control the trains has a current rating of 10 AMPS at 24 VAC, so this should be capable of controlling even the most "current-hungry" O-gauge locos.
- Reference the Z-Stuff DZ-1008 relay instructions at zstuffexpress.com/_files/ugd/ffc73c_14b5794af32e473187c64e928f87b96e.pdf

3. Video Part 1: ("Delay From Front")
- Part 1 shows a Z-Stuff DZ-1012v Infrared Block Signal Detector placed at the END of an isolated "Stop Block" in the center-rail.
- The Detector's time delay is used to cut off the power in the block -- which will STOP a following train that is following too closely behind a leading train that just passed through the block.
4. Video Part 2: ("Release From Rear")
- Part 2 -- using the "Release From Rear" method -- shows a Z-Stuff DZ-1011 Infrared Block Signal Detector placed several train-lengths "UPSTREAM" of an isolated "Stop Block" in the center-rail.
- When the following train activates the Detector, the connected relay will START the leading train that is stopped in the Stop Block.
~~~
- Although a DZ-1011 Detector was used for this Part 2 demo, the newer DZ-1012v Detector is recommended.
- The "Delay From Front" method shown in Part 1 is the RECOMMENDED method. But in some cases this "Release From Rear" method may work better.
5. Related Earlier Discussion:
- Note this Part 2 "Release From Rear" method has a logic similar to the "Insulated Rail" method (discussed in an earlier Video #667, and described in the 8/2018 thread here: https://ogrforum.ogaugerr.com/...lays-nor-electronics .
