"The extension of Line 1 marks another
important step in the expansion of the metro-rail system in Salvador. 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 modernization of our network", says José Eduardo
Ribeiro Copello, CTB's President Director.
“The extension of Metrô Bahia
Line 1 is excellent news for the people in the City of Salvador. It is a
further step of the State of Bahia’s Administration to provide access to
comfortable, safe, and sustainable transport. With the supply of
state-of-the-art digital signaling systems, Siemens Mobility is proud to be
part of this important innovation project”, says Andreas Facco Bonetti, CEO of
Siemens Mobility in Latin America.
Siemens Mobility will provide
the software update for all onboard units on the existing 40 train fleet and for
both Operation Control Centers (the main one and the backup). This contract also
includes the installation, testing and commissioning of a radio
system, electronic interlockings, and wayside equipment.
The Salvador Metro started operations in 2014 and is managed as a Public
Private Partnership (PPP) by concessionaire CCR Metrô Bahia and the State of
Bahia’s Administration. The system comprises two metro lines extending 32 km,
with 20 stations, 2 OCCs, 2 depots, and utilizes a 40-train fleet to move 370
thousand passengers per day.
Siemens’ intelligent solutions
played a key role in the creation of this system, including the installation of
the signaling, train control, catenary and telecommunications systems. The
control system Trainguard MT, implemented by Siemens Mobility between March
2015 and July 2018, allows for the automatic train operation to be activated
with a train operator onboard (Grade of Automation level 2). Even though the
conductor starts the train manually, the system automatically takes over
acceleration/braking and speed control between train stations and determines
the train’s stoppage and the opening/closing of doors at stations. The system
also allows for driverless maneuvers in the turnback areas.
In developing the
telecommunications system, Siemens Mobility successfully integrated the data
transmission, fixed communications, multimedia, message panel and timing, as
well as the electric monitoring and radio subsystems. Siemens Mobility was also
responsible for the complete catenary supply (distribution and electrical
supply system for traction) in 3 kVcc for the trains.
The radio based CBTC technology provides real-time data on vehicle
position and speed conditions, allowing system operators to safely increase the
number of vehicles on a rail line. This results in greater frequency of train
arrivals and will allow Metrô Bahia to accommodate more passengers on its
system. Additionally, the technology precisely locates each train on the tracks
and controls speed, improving safety for riders and employees, while also providing the ability for continuous
updates on system status that results in fewer delays and up-to-date travel
information.
The Siemens Mobility CBTC solution
Trainguard MT is the most extensively deployed automatic train control system
in the world and is also used by many operators in Latin America, like São
Paulo and Buenos Aires, and around the world, including Paris, Beijing, and New
York.
