The award of the €17m (£14.2m) contract for Subterráneos de Buenos Aires (SBASE) follows an international public tender process.
Line B, in operation since 1930, is about 10km long and includes 18 stations. This project will increase the line’s capacity, benefiting the 250,000 passengers that use the service daily. Alstom already provided signalling systems for Line B in 2005 with an extension in 2013.
The scope of the new 15-month project includes the design, assembly and commissioning of medium-voltage ring cables, third rail power and tunnel disconnections. It also includes modifications in substations and other complementary systems in the power supply.
