In 1994, the subway network connected Line 1 to the Caracas valley with the opening of Line 3, which joins the main line (L1) in Plaza Venezuela and reaches to La Rinconada, covering the North-South axis of the city.
This Line has 9 stations and covers a total of 11.47 km (7.2 mi). The first stage (Plaza Venezuela - El Valle) opened in 1994, has 5 stations and covered a distance of 5.7km (3.11 mi). The second stage was opened in 2006 and has 5 more stations. This stage links El Valle station with La Rinconada multimodal terminal, which connects to the metropolitan railway that goes to Los Valles del Tuy, in Caracas' outskirts.
From March 1993 to March 1994, during the construction of stage 1 of Line 3. Telematica installed, tested and commissioned the Centralized Control System (SCADA) in the Operations Control Center (CCO) and the stations.
From January 1999 to December of 2008, Telematica performed preventive and corrective maintenance duties at the Operations Control Center and the system's fixed communication devices.
In May 2009, we started the installation and commissioning of the Automatic Train Operation (ATO) system on Metro de Caracas' second stage of Line 3. We were hired by Thales to execute it. It was completed in March 2010.
Simultaneously, in a joint work between SYSECA, S.A & THALES, from June 2006 to July 2010, we completed the supply, installation, testing and commissioning of several systems: SCADA; Fiber optics data transport network; PABX and emergency telephony; public address (PA) and passenger information system (PIS), closed circuit television (CCTV), and radio communication system in tunnel and stations. We also performed the technical-administrative coordination for the train control and communications group for this project.
