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.

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.
The HXP-3 offers two multi-functional recorder options to
enhance record keeping, improve maintenance, and reduce
installation time. The first option is the HXP-3’s original RMM,
providing the following records for all HXP-3 configurations:
Train record log – reports all HXP-3 inputs and outputs
System event log – an accurate time-stamped sequential
log of all HXP-3 input and output status changes
Train data log – a time-stamped data log containing RX and
phase changes related to individual train moves
External event log – event logging for up to 14 optically
isolated digital inputs and 4 analog outputs (requires use
of a recorder interface module)
Onboard storage of local parameters transfers setup
information between normal and standby systems to reduce
installation time.
The second recorder option is the HCA-3 module. It provides
the following standard recorder logs (train record, system
event, train data, and onboard storage of local parameters)
as described above. The HCA-3 module also provides these
enhanced recorder features:
HCA data log – event logging for up to 14 optically isolated
digital inputs and 4 analog outputs in a GDA compatible
format (requires use of a recorder interface module)
Can be programmed with existing HCA-1 ALP executable files
Allows data retrieval either by a modem/serial port interface
or through the HXP-3’s CPU module
Offers compatibility with all HCA-1 software utility programs
