Project Summary: Signaling panel and field installation on the Mecidiyeköy – Mahmutbey metro line

On a metro line, signaling is the system that keeps trains at a safe distance from one another. Tiva Enerji carried out the field and panel installation of this system for Bombardier on the Mecidiyeköy – Mahmutbey line.

Field end element installation

Field elements such as TRA, loss antennas, TRA filters and norming points were installed along the line. These are the devices that report the train's position and speed to the system; their locations are fixed to the millimeter, and incorrect positioning leads to signal errors.

Signaling panels

DCC/BEC, OBC, DTS, DTS Station, OTC, ATC and WMPP panels were installed at the stations and along the line. Each panel carries a different layer of the system: some handle onboard communication, some station control, and some automatic train control.

What makes rail work different

The work window on a metro line is narrow: most of the work is done at night when service stops, and the line has to be handed back in the morning. This calls for tighter planning than factory work; how far the team will get each night is set in advance.

Result

The field elements and panels were installed and handed over. This project shows that the team can work with the discipline rail systems require and within narrow time windows.
