NEW! 21st Century Signal System


(Pre-production sample shown)

Atlas O is proud to introduce a quantum leap in signaling realism. For the first time ever in the O market, the Atlas O Signal System not only features signal fixtures that have true ¼” scale dimensions and details, but also includes the circuitry for true prototype operation.

A perfect complement to the incredibly realistic and extremely reliable 21^st Century Track System, the signal system can be used as a stand-alone accessory, or can be connected to one another for complete integration.

Easy Hook-up – as simple as 1, 2 ,3!

*1 – Connect power from transformer to signal circuit board.

*2 – Connect a single wire from an insulated track section on your 3-rail layout (or detector on your 2-rail layout).

*3 – Plug in your signal to signal circuit board.

It’s that easy!  

Frequently Asked Questions

Q. What do you need to get started?
A. The number of signals and detector boards you use depends on the size and complexity of your layout. In 3-Rail, you don't need a separate detector, as it is already built into the signal control board. For 2-Rail, the easiest way to get started is to use the complete, all-in-one pack Type G Signal Kit, #7930, or it's larger 4-pack version, #7934. More information is available in the manual that comes with the signals.

Q. What does the signal control board (SCB) and the block detector board (BDB) do?
A. The signal control board and block detector board comprise the electronic “brain” of the system. The block detector senses current flow in the block. Installed under the table or mounted under your layout, the control and detector boards are capable of four broad modes of operating options. They control the input from the block detector board and output to the signal target head.

Q. How does the stand-alone signal operation work?
A. The Red and Green are controlled by occupancy. The Yellow is the controlled timed feature in this mode of operation.

Q. Where do I install the signal?
A. The signal is normally placed at the entrance to a block. (A block is any section of track that is electrically isolated from the rest of the layout.)

Q. How do I add integrated signal operation?
A. To add integrated signal operation of two or more signals, plug in the modular Atlas Signal Cable - Item #s 6937 (7’), 6938 (15’) & 6939, (25’), in the length that is appropriate to your block size. Next, plug the cable into a jack, (RJ-11), on the first signal board and into the jack, (RJ11), on the other signal board. Jack 3, (RJ12), is where the signal plugs in.

Q. How does the integrated signal operation work?
A. Installation of the Integrated Signal Cable automatically disengages the timed Yellow feature of the stand-alone signal. All aspects are now under full control of the blocks and signals in front of and behind your train. (See manual for details.)
