Red Means STOP

Well folks I have spent the better part of the weekend installing two Atlas signals that I acquired at a recent train show. They are impressive devices and add another area of operating interest to the layout. They have the ability to become fully integrated with the Signal control boards (SCB) actually connecting to each other and displaying a color of signal appropriate to the occupancy of the block before it and after it. For now though I have them operating in independent mode, so that when a train enters the corresponding block, the signal goes to red and then yellow (timed for 8 seconds) when the train leaves that block, then back to green The SCB is controlled by a block occupancy detector - in this case, a NCE BD20. One word of advice though make sure you have good lighting under the layout, as the screw terminals on both devices are very small and difficult to get the wires in when you are underneath a layout looking up...my neck is still sore. Till next time....
