GE Transportation The Phase Motion Detector PMD-3 monitors train approach directions from 240 to 7,500 feet (2,286 meters), activating warning signals at the specified pre-set distance. The PMD-3 shares module compatibility with the GE - Transportation HXP-3 crossing processor’s advanced microprocessor technology. This helps improve the economy of the PMD-3’s long-term maintenance, while its design flexibility helps reduce total installation expense and training cost.
