Signal design

SEPTA is modernizing and increasing the resiliency of its signal power supply system by providing solar power reinforcement technology for rail signals on its Regional Rail lines. SYSTRA is responsible for signals design and engineering services for the installation of solar supply and distribution systems.

The first project on SEPTA’s system in which solar panels will be used to provide signal power, it will improve safety and sustainability and help reduce energy consumption and greenhouse gas emissions. Providing a backup power source, the solar panels will be an advantage during severe weather, meaning the signal system can run for two days if the primary power source fails.
