I was looking at the Atlas 21 Century system as well as Custom Signals equipment. Right now I am only planning on using 3 signals and a single track main. I was then thinking about Bi Directional signals from Custom. Anybody have suggestions or comments on using either the bi directional signals or using 6 single signals on both sides of the track. I watch the tutorial on erics trains website using Atlas and it looks really cool

That is absolutely true if you hook the signals up the correct way   Three signals would always be yellow or red with a block system  The Custom signals do have a timer circuit if you want to use them that way. We use Atlas/Custom signals   Have had them installed on our outer loop since 2006 without a problem   That loop uses 15 blocks though.

We have a mix of MTH and Z-Stuff signals. The MTH signals are triggered by insulated rail and relays. The Z-Stuff are using the optical sensors for now. We have a couple of Atlas signals that work nicely, but two others got sheared off in a derailment. The MTH and Z-Stuff are a little sturdier.

 

You can pretty much integrate any signals to work together if you have enough wire, enough relays and sensors and enough patience. I haven't tied our signals together as they're more for traffic control around layout blind spots rather than true block control.

I think signals by Z-Stuff are the best.  My favorite part of using their signals is that the  detector is built in.  No need to spend extra money or work on detectors. 

 

I do have signals from MTH and Right-Of-Way Industries on my layout.  Both of which I enjoy as well.  But in recent years ALL new signals bought have been by Z-Stuff.

It isn't completely clear to me whether you want to have a block signal system (which would provide a Stop indication and an Approach indication for both opposing and following trains, and signals would change to reflect the location of the train and the position of turnouts) or operating signals (which would be activated and display a Stop indication when a train is passing, and then upgrade to Approach, and then to Clear on a timer, even if the train has stopped just past the signal).

 

There's nothing wrong with operating signals.  That's what is most commonly installed and it looks nice. However the drawback is that it is strictly a simulation and cannot reliably indicate occupancy of the track.  To have a block signal system, you must divide your track into blocks (by using an insulated joint in the outside rail) and each signal is controlled by a relay.  The relay is also connected to the switch machines of any turnouts in the block, and to the relays in both adjacent blocks.

 

It is not terribly complicated.  The Atlas/Custom Signals system is easy enough for the average person to install, and they have good support material on the website.

 

It can get expensive, although it could be installed in stages.  The track must be divided into blocks when laid, but the signals do not have to be installed all at once if money is an object.  I have 32 block signals on my layout.  However, I have two wyes, a crossing at grade, a two track main line, and a passenger main track through town.  But I am a retired railroad official and I want a fully functional automatic block signal system.  I could have installed 4 blocks on each track of the two track main and had an automatic block signal system.  It would have given trains a Restricting indication any time they left the main track to enter a wye, yard, or the passenger main.  The crossing at grade would have been unprotected.  I can't say that it would have taken the fun out of the layout, but part of the fun, to me, is the block signal system.  And the signals add realism.  There is yet work to be done, as I am adjusting their placement a little bit and most of the mounting bases still are visible.  One by one, they will be camouflaged at the base and will be more realistic looking.

Most of my Signals are from MTH, being a B&O guy, many are color position. I control them with an isolated rail and where needed micro switches at switch points. To control the signal indication, I use 12volt DC relays from Radio Shack and wire in a full wave bridge to the coil circuit. That’s much easier, smaller and cheaper than an AC relay.
Where an isolated rail would be impracticable I use Z-stuff signals or controls
My signals don’t follow exact prototype operating practices, but close enough to give a realistic impression.

Utilizing z stuff signals and signal bridges.The down side is with my rolling stock weathered the bridges not the standard signals inconsistently don't see some rooftops(pending color) and cause chattering of the signal, Iam adding soon an I pad system for operation and detection which hopefully will remedy the problem by using a different sensor to see the train and keep signals correct.

Mike,  I like the look of those Atlas dwarf signals.  But I can't tell if they use LEDs or mini bulbs.  Could you enlighten me?  My guess is that they are LED's, from the way they are wired to the supplied PC board.  They are designed to connect to other Atlas signal systems and the 6924 universal control board.

The 6931 (6935 set of (4)) dwarf lights are wired to Atlas switch motors as shown. There are some alteration for multiple switch motors as one throw.  If the switch motor impedance is not within spec. a replacement motor has to be used.


The concrete bases were fabricated from medium density particle board, not part of the dwarf light.

(Moments more and Rich is still giving Scrappy a washout and now has also thrown his cap onto the ground and is jumping up and down on the cap): *&%#@

 

*&%#@ is "Gee, you're on the Ground," on steroids.  The stomped cap is an extra, normally only used when you are the guy who's going to have to re-rail the engine.

 

That's how it's done with hand signals.
