From fully automated, integrated solutions to upgradeable solutions and overlay re-signalling techniques to reach beyond the limitations of conventional fixed-block designs, SelTrac system solutions readily meet your needs to move more people more quickly and increase revenue potential.

Applicable to any type or size of rolling stock and dedicated guideway, SelTrac system solutions are flexible and adaptable enabling customers to employ a complete, high-end system or incrementally upgrade functionality over time, without disrupting operation. Transit operators retain the value of their original investment as they expand and grow their systems. SelTrac can be configured easily to meet the specific functionality needs of the operation. With built-in flexibility, SelTrac addresses the diverse requirements of operators needing basic Automatic Train Protection (ATP), cab-signalling, or CBTC-based operations. From simply replacing existing signalling, to improving the headway performance of an existing fixed-block system, SelTrac is the convenient and cost-effective solution.

Our premium SelTrac solutions include “moving block” technology for unattended/driverless operation. These systems offer excellent operational flexibility under even the most demanding of conditions. And, to meet high or increasing capacity situations, SelTrac has proven that it can deliver headways of under sixty seconds, better than normally required.
