BRAZIL: Bahia state transport authority CTB has awarded Siemens Mobility a contract to supply communications-based train control to support GoA2 attended semi-automatic train operation on a 5 km extension of Salvador metro Line 1 from Pirajá to Águas Claras/Cajazeiras, including two stations.
Siemens Mobility will install, test and commissioning a radio system, electronic interlockings and lineside equipment, and update software on the 40 existing trains and at the main and back-up control centres
The contract announced on May 6 builds on an established relationship with the supplier, with Siemens having supplied the signalling, Trainguard MT train control, 3 kV DC overhead electrification and telecoms for the two-line metro which opened from 2014. The ATO implemented by Siemens between March 2015 and July 2018 enables the driver to start the train manually, with automatic acceleration and braking and door operation. The system also supports driverless turning back of trains.
‘The extension of Line 1 marks another important step in the expansion of the metro system in Salvador’, said CTB President José Eduardo Ribeiro Copello. ‘CTB is proud to be expanding its services together with its concessionaire CCR Metrô Bahia. We are pleased that Siemens Mobility will continue to contribute significantly to the modernisation of our network.’
