Siemens Mobility to modernize three lines of São Paulo's transport network in Latin America’s largest ATO over ETCS project
Siemens Mobility has secured a contract from Trivia Trens
S.A. to deliver and implement a complete, digital signaling system featuring Automatic
Train Operation (ATO) over ETCS Level 2 for São Paulo's commuter rail lines 11-Coral,
12-Sapphire, and 13-Jade. The project covers 140 kilometers of track and 46
stations, marking Latin America's largest implementation of this advanced rail signaling
technology. The contract includes equipping 107 trains, six locomotives MRS,
three locomotives TRIVIA and 17 auxiliary vehicles (yellow fleet) with Trainguard
ETCS (European Train Control System) on-board units.
"This landmark project demonstrates our
commitment to bringing cutting-edge rail technology to Latin America,"
said Marc Ludwig, CEO of Rail Infrastructure at Siemens Mobility.
"By implementing ATO over ETCS Level 2 in São Paulo's busy metropolitan
transportation network, we're setting new standards for automated urban rail
transportation in the region and up to 30% increased network capacity. Together
with our client, we implement
the largest ETCS Level 2 project in South America."
The comprehensive scope includes the design, supply,
installation, commissioning and assisted operation of the signaling system
across the three lines, equipping various train types from various manufacturers
with state-of-the-art Trainguard ETCS onboard units. The solution encompasses
key components such as an Advanced Traffic Management System (ATS), modern
interlocking systems, Radio Block Centre (RBC), and complete trackside
equipment, backed by a two-year warranty period and spare parts provision.
ATO over ETCS represents the cutting edge of rail technology,
combining two advanced systems to maximize operational efficiency and safety.
While the ETCS Level 2 provides continuous digital supervision and control of
train movements via TETRA, the ATO system automates driving functions to Grade
of Automation (GoA) Level 2. This technological integration enables precise
acceleration and braking patterns, exact stopping at platforms, and optimized
headways between trains.
The implementation of this advanced technology will transform
São Paulo's commuter rail line operations through enhanced service frequency
and reliability. The system's optimized driving algorithms significantly reduce
energy consumption and peak power demand, while its streamlined architecture
minimizes maintenance requirements. With fewer trackside components and the ability
for future upgrades, this solution represents a future-proof investment for São
Paulo's expanding mobility needs.
