The Government of São Paulo, through the Secretariat of Investment Partnerships (SPI), will hold the auction for the Alto Tietê Lot on Friday, March 28. This lot includes a sponsored concession for train Lines 11-Coral, 12-Sapphire, and 13-Jade. The public bidding session will take place at B3, in São Paulo, and involves a planned investment of R$14.3 billion over the 25-year concession, with significant improvements for passengers and an expansion of the services offered.
The concession will bring operational, structural, and technological enhancements for passengers, including upgrades to all three lines and the expansion of the rail network. Ten new stations will be built, and 24 existing ones will be renovated. All level crossings will be eliminated and replaced with overpasses, underpasses, or pedestrian bridges, improving passenger safety and easing urban traffic flow.
The lines will also receive investments in overhead systems, permanent way, and signaling, along with the implementation of new equipment and systems. By 2040, the three lines are projected to serve a combined average of 1.3 million passengers per weekday.
The concession will reduce train headways, ensuring more efficient operations across the lines:
Line 11-Coral:
Headways will be reduced to 3 minutes between Palmeiras-Barra Funda and Suzano, and to 6 minutes between Suzano and Cezar de Souza. The line will be extended by 4 km to reach Cezar de Souza Station, with service expanded to Barra Funda. Four new stations will be added, 14 renovated, and three completely rebuilt. All level crossings will be removed and replaced by overpasses, underpasses, or walkways.
Line 12-Sapphire:
The interval between Brás and Itaquaquecetuba will drop from 5 to 3 minutes and 15 seconds, and from Itaquaquecetuba to Suzano, from 10 to 6.5 minutes. The line will be extended by 2.7 km to reach Suzano and will gain two new stations. It will also integrate with Line 13-Jade and Metro Line 2-Green. One station will be rebuilt, and 12 others will undergo renovations.
Line 13-Jade:
Headways will be reduced to 10 minutes, and the line will be extended to Bonsucesso, with 15.6 km of new track. Six new stations will be built, and three others renovated. The Airport Express will run every 30 minutes during off-peak hours and every hour during peak times, with a new stop at Gabriela Mistral Station, providing connections with Metro Line 2-Green and Line 12-Sapphire.
The new contract introduces several regulatory improvements and innovations, including an initial investment program and a 24-month operational transition phase, with training and assisted operation by the concessionaire. This phase aims to ensure a smooth transition from CPTM management to the new operator, offering greater safety and service continuity.
The project also includes studies on climate resilience and extreme weather events, reinforcing operational safety and service reliability under adverse conditions.
Attractiveness for National and International Players
With a sponsored concession model that includes government contributions and availability payments, the Alto Tietê Lot auction has drawn interest from both national and international players. The São Paulo government has held meetings with investors in countries like France and Italy and is also exploring opportunities in the Asian market, reaffirming its commitment to attracting qualified bidders and boosting competition.
The concession of the Alto Tietê Lot will have a strong social impact, serving the East Zone and high-demand metropolitan areas where over 4.6 million people live. The project is designed to expand access to high-quality public transport, cut travel times, and ensure greater comfort and operational efficiency for passengers.
