SBASE, the public body that manages the Buenos Aires metro, has launched a tender worth $US 1.35bn for the construction of the new Line F. It will be the first expansion of the Argentinean capital’s metro network for 25 years. The project comprises a 9.8km underground line with 12 stations, linking Barracas and Constitución in the south with Recoleta and Palermo in the north, and providing interchange with all six existing metro lines as well as Constitución mainline station. The new line is expected to carry over 300,000 passengers each day. The tender, which covers engineering, construction and equipment work, includes a 20% advance payment, and requires completion within 60 months. The deadline for bids is April 26. Network upgrade Separately, Sbase has launched a $US 250m procurement programme for upgrades of the existing network, aimed at improving capacity, reliability and asset life. The programme covers improvements to infrastructure, including station upgrades, power supply and signalling systems and rolling stock, with work expected to begin later this year. A key element of the programme is the modernisation of Line B’s traction supply system, which is set to switch from 600V dc to 1.5kV dc, enabling higher-capacity operation and compatibility with newer rolling stock. Sbase plans to acquire around 40 new trains for lines A and C, valued at approximately $US 51m, to add capacity at peak times, and replace ageing vehicles. At the same time, Sbase will undertake a project to refurbish the existing fleet, including mid-life overhauls, while progressing potential procurement discussions for major multi-line fleet orders. The upgrades to the metro network form part of Buenos Aires’ wider 2026 infrastructure investment strategy, which significantly increases funding for public transport.
