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. Double-track units
can use different frequencies on each track. Units work on
approaches from 240 to 7,500 feet and accommodate remote
installations having up to 3,500 feet of track wire.

The HXP-3 offers enhanced rusty rail performance and is
compatible with high-current cab signals. It shares module
compatibility with the PMD-3 and the HXP/PMD-3. It includes
all features found in earlier HXP models as well as more
advanced operating and recording options.

The HXP-3 is available in three models:
HXP-3 provides stand-alone operation for single or double
track applications.
HXP-3R provides built-in redundancy for single track
applications.
HXP-3R2 provides built-in redundancy for single or double
track applications.
