Project assignment by TOMI SA for signaling studies within the project “Rearrangement and upgrade of the signaling system – remote control and replacement of 70 track changes in localized sections of the axis Athens – Thessaloniki – Promachonas” (ID 717)

1. Study of modification of auxiliary traffic light Σφ5 in the entry and exit traffic lights of the stations
2. Study of adding a slip path
3. Study of addition of timing for the cancellation of a blocked route
4. Study for the modification of the interlocking system of the stations “Theba” and “Eleon” after the abolition of the exclusion position “Ypaton”
5. Study of modification of the interlocking system after the abolition of existing track changes at the stations of Theba, Sphinx, Aliartos, Livadia, Doxaras, Kranon and Mezourlos
6. Study of modification of mimic control panels, so that during the movement of the trajectory changes, a flashing indication appears, which will be stabilized after the detection of the change in a specific position (straight or bypasses)
