Use this Controller to light and controller your G Scale Dwarf Signals from Model Train Technology.

After a short delay we have been able to include full signal interlocking into the product.  This started with a few request for a way to use the D-Signal Controller to light the aspects in a three-way switch.  We got that working in a few days but then realized that a three-way switch is just two switches merged into one with one being primary and the other “interlocked” with the first.  In other words, when the first turnout is turned AWAY from the second one, it blocks a path to the exit.  In that case, BOTH signals of the second turnout should show Red regardless of the physical position of the switch.  Then, we decided that if we could simply cascade that through many turnouts we would be able to have a complex interlocking system without a computer and without much fuss.  All that is working and it is pretty slick!

In order to use the Coil Sensor your switches must be running on 12-16v DC, not AC.  The turnouts will operate just fine on DC and its and easy thing to switch over.

Dwarf signals are typically used in yards and siding to indicate the direction of turnouts.  Thus, each turnout would have at least two signals.  It also is possible to have a  Dwarf signals at the head the turn where Green means mainline and red means siding.  Another words, facing in the opposite direction.

The Model Train Technology Dwarf Signal controller is a FOUR light Fiber Light Controller.  This provides for signaling for two turnouts.

This product comes with two dwarf signals each with 36″ of fiber cable and the associate pins.   Additional dwarf signals can be purchase on the store.

You will use 2-core fiber pins (included) so that the Red and Green are swapped between the two Dwarf Signals.

The Dwarf Signal Controller can be trigger in one of five ways:

1. Operation of a stall- type actuating motor
2. Snap-like coil switch machine – this requires the MTT Coil Switching adapter
3. DCC Mirroring
4. Precision Detector
5. Mechanical Toggle or spring loaded center switch

The Coil Detector is only available with the purchase of a Dwarf Signal Controller.

TO save cost we designed the Diode Board and this board to be swappable.  This board DOES NOT have diodes but is a simple “Connect ALL” board.

For more information on how to install and use this board, see the video below:

THIS IS THE EASIEST way to add Triggered Block Signals to you layout with the minimum of wired and fuss.  The two fibers from the Block Signal go through the layout base and connect directly into the Controller.  You will use two ports – one for Red and one for Green.  Then,  connect your favorite Track Detection system (how about our new IR or Magnetic detectors?).  The detector can be powered from the Controller (5VDC) and then only one signal wire connects to the controller.

Set the controller to ports to the Block Signal setting using the simple keypad (it takes about 60 seconds) and then push the green button on the controller to start the animation.  When there is no train the light will be GREEN.   When the detector “sees” the train the controller will get a signal and switch the fiber light port from GREEN to RED.  It’s that simple!!

Each port has TWO Fiber Lights – thus you can have two block signals run by one detector circuit – one for EAST and one for WEST.

Configured this way,  the Fiber Lighting Controller can support 8 detector and 4 pairs of Block Signals/Circuits.

A 3-LITE version will be available in February 2021. This will require a separate 3-Lite Fiber Lighting Block Signal Controller.

Our Block Signals are 3D printed using the most advanced SLA printed technology available.  If you want to lite your own block signals,  just order the Signal Light Kit which includes 10′ of fiberoptic cable and the fiber pins that can be used with our Fiber Lighting Controller.  Coloring the lamps takes some practice.  We fasten the cable with both CA glue and Bondix resin glue.  You can bend the cable with hot water and cut it with very sharp snippers.
