Crossing signals for Pandora

I just completed installing a set of crossing signals in the Pandora switching portion of my layout.  These crossing signals add a level of detail and animation that is eye-catching, and certainly fun to watch as a train approaches the road crossing.  The installation was simple, once I figured out the product to use.  The photo shows the circuit that I purchased, as well as the crossing signals themselves:


These are the products used to add animation to the road crossing in Pandora.  Note that I used two sets of the crossbucks to protect the two tracks.  Not shown are the photocells used to activate the crossbucks.
The Logic Rail Grade Crossing Pro is mounted under the layout.  The unit is provided with four photocells, which are installed between the ties, two on each side of the grade crossing.  As a train approaches the grade crossing, the first cell is covered, turning on the signals.  The circuit has built-in logic that maintains the flashing until the train has cleared the fourth photocell on the far side of the grade crossing.  This allows even short motive power, such as the Galloping Geese of the RGS, to correctly trigger the system.


D&RGW C-19 347, a Blackstone Models Consolidation, is approaching the grade crossing in Pandora.  Note the flashing LEDs of the NJ International Crossbucks.
