GE Transportation The HXP-3 series of constant warning time crossing control units from GE - Transportation provides consistent detection times with varying train speeds. Interfacing advanced microprocessor technology with long-term reliability, ease of maintenance, and design flexibility, HXP-3 systems help reduce total installation and maintenance expense. With a single island module for all crossings, this processor provides single or double track monitoring.

Options Accessories An Auxiliary Crossing Driver module (AXD) provides the HXP-3 with three additional independent constant warning outputs which may be used for: Remote start operation. Traffic signal preemption. MD relay drive function when two relay drives are required at a double track crossing. A single AXD relay drive output to control both tracks at a double track crossing. Shunts NBS-1 with 10 ft (3.048 m) leads NBS-2 with 10 ft (3.048 m) leads NBS-3 with 10 ft (3.
