Replacement of Interlocking Power Supply System
At A.I.R. Station—the largest depot area managed by the Greek Railway Infrastructure Manager—Sigma Signal undertook a critical project to upgrade and maintain the station’s aging power supply system. Recognizing the importance of uninterrupted operations in such a vital hub, Sigma Signal carefully designed and executed all necessary activities, including the provision and installation of the needed equipment. The upgrade ensured that the station’s traffic control system continued to operate seamlessly throughout the process, maintaining full functionality and avoiding any disruptions to daily operations.
