The latest release in the Atlas O 21st Century Signal™ System is the much-requested PRR Position Light Signal. This unique signal design was a familiar sight on the far-flung PRR system and remain in use today. Like all 21st Century signals, it is constructed of finely-detailed brass, die-cast and ABS parts and features amber LEDs and the same easy, realistic operation that is acclaimed hallmark of the Atlas O system.

Available in both separate-sale and convenient 4-pack packaging. For both 2 and 3-rail operation.

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!
