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. |
