This HO scale RR Crossing is part of a prototypical fiber optic lighting system that provides the ability to have a fully integrated RR Crossing system with automatic train detection (and an optional bell sound, available separately).

It is designed to be used with our dedicated crossing flasher box. Each crossing flasher has a single flashing face and comes with 4ft of 1.0mm fiber attached to it.

To mount the crossing flashers, just drill a 1/8" hole in the layout, insert the fibers and then the tubing to the desired depth. The size of this hole will provide a snug fit for the RR Crossing post, keeping it from swiveling around.

The integration of the Crossing with the detectors and sound is shown in the block diagram below.

Features of the Dwarvin HO Scale Crossing Flashers

• Activated by two state-of-the-art infrared proximity sensors. (Tolerant of ambient (background) lighting conditions, be it completely dark or under full lights, with no false triggering.)
• Includes 2 electrical cabinets to conveniently disguise the infrared sensors.
• Includes convenient mounting bracket to hold infrared sensors in place under the layout.
• Built to true 1:87th scale dimensions (HO scale).
• Ideal for any modeling era.
• Can be powered on existing accessory DC power (includes adapter plug) or power with the optional110V power adapter.
• Additional infrared proximity sensors available separately for grade crossings with more than 1 track.
• Easy installation, under 20 minutes from start to finish! Requires drilling 4 holes (two for the crossbucks, 2 for the infrared sensors).
• Individual Crossbucks available separately (you never have to buy a whole kit to repair a damaged crossbuck!).

Application:

Applicable for a single-track grade crossing. To accommodate additional tracks purchase 2 additional proximity sensors to monitor the additional track.

Dimensions:

• Height: 3 1/4" (8.25cm) to the top, 2 1/4" (5.7cm) to the lights
• Width: 3/4” (2cm)
• Diameter of Fiber: 1mm
• Length of Fiber: 4ft
