Automated Switch Control Post of Figeac Station

Project Description

On the night of November 21 to 22, 2018, Figeac station suffered a severe fire, causing the interruption of rail traffic on the Brive–Capdenac and Aurillac–Capdenac lines. Service on the first line resumed a few months later, while the second line restarted in October 2019, limited to the Figeac–Aurillac section and supplemented by a bus service.

Before the fire, Figeac station was equipped with a relay-based geographic wiring interlocking system (PRG). This project aims to restore the operational situation that existed before the November 2018 fire. In particular, the objective of this contract is to create a computerized interlocking post of the PAI 2006 generation to replace the PRG destroyed by the fire.

Our Services

The passenger building (PB) housed the PRG signaling post along with its electrical supplies, as well as the electrical supply for several SNCF RESEAU installations (tunnel lighting, building facilities, etc.). The scope of work requires transferring several circuits from the PB’s main electrical panel (TGBT) to the PAI’s “Building Distribution Board.” To achieve this, TRACTEDIS conducted a detailed survey of the exact characteristics of the TGBT circuits in the PB. Additionally, TRACTEDIS carried out an inspection of the civil engineering power routes and electrical supply cables on site. Following these identification missions, TRACTEDIS developed updated electrical diagrams reflecting the current state of the fire-damaged site.
