Signal System



INTRODUCTION

There is no single model railroad accessory that captures the essence of prototypical railroading more than an operating signal system. Whether standalone or as part of an integrated system, a working signal adds both visual and operational interest to your railroad.

The Atlas All Scales Signal System enables you to provide realistic information to your train crews in a simple, yet expandable way. Our growing line of signal heads, masts, and bridges spans most common modeling eras, and are easy to install on your layout. The signals feature true scale dimensions and details, and are available in single and double head arrangements, as well as several multi-track bridge configurations. Regardless of scale, all Atlas signals now utilize a small standardized connector and separate cable to connect to the signal control boards, minimizing the impact of installation on a layout with existing scenery.

The Signal Control Board can operate standalone, or as part of an integrated system to replicate the behavior of many North American prototypes, providing selectable 2 or 3 block (ABS) operation, flashing aspects, approach-only, and PRR and color position light options. It can drive either common cathode or common anode signals, and can be powered by AC or DC. The system can be used on layouts operating on either analog (DC or AC) or Digital Command Control (DCC) power through the use of appropriate block detectors (not available from Atlas), and can also be manually controlled.


OPERATING OPTIONS

Stand Alone Operation: in this case a single signal runs independently of other signals, and displays appropriate aspects, such as red – yellow – green, in a timed manner. The signal turns red when a train enters a “block”.

Integrated ABS Block Signaling: Connecting a number of Signal Control Boards together in a daisy-chain fashion enables you to represent a prototypical block signal system, where the occupancy of the blocks ahead and behind your train determines the aspects displayed by the signals. The number of blocks is controlled by a simple jumper setting on each signal control board. A block detection system (either DC or DCC) is required.

Approach-Only Signaling: To better support prototypes whose signals do not illuminate until a train is nearby, the Signal Control Board has a setting to enable this behavior when connected in an integrated system.

Flashing Aspects: On some railroads, in order to increase the number of indications available to train crews, such as intermediate restrictions, certain flashing aspects are used. These aspects are now supported with flashing yellow and green options, and are automatically enabled for certain prototypes by a single jumper setting.

Complex Signaling and Interlockings: In combination with our new Turnout Control Module, simple turnout indication or complex route-based signaling is possible. COMING SOON!

Manual Control : Full control of signal aspect for Red, Yellow, Flashing Yellow, Flashing Green (with appropriate auto return to Green) is available for those wishing to create the ultimate in CTC-like systems.

THREE-STEP QUICK START SETUP

1. Plug any Atlas signal into the universal attachment cable (70 000 050) and then into the Signal Control Board.
2. Connect a single wire from your block detector of choice (DC, DCC, Optical) to the Signal Control Board.
3. Connect power from your transformer to the Signal Control Board.

FEATURES

  • Signal Control Board is universal, whether you model in N, HO, or O, AC or DC!
  • Common cathode AND common anode signals supported
  • Backwards compatible with original Atlas signal products
  • Accepts DC, DCC and Optical detector input for block detection (detectors not included)
  • Expanding line of signal heads and configurations available to fit many eras and prototypes
  • True Prototypical operation (ABS) for 2 and 3 block systems
  • Flashing Yellow or Lunar White modes are selectable, and Flashing Green aspects are supported
  • Easy to extend the system as your railroad grows by using simple telephone-style cord connections
  • Modular design with standardized plug connections between signal heads and boards
