Metro de Santiago has commissioned Ineco to carry out detailed engineering on the refurbishment of its Alstom NS74 trains, the first to operate in the city’s suburbs. The project involves a total of 35 trains with pneumatic running gear, a total of 245 carriages. Manufactured between 1974 and 1981, they have reached the end of their service life but are being refurbished, a process that began in 2011 and will provide them with another 20 years of operation.
Since then, Ineco has been providing services to Metro de Santiago to supervise the entire process, which includes replacement of engines, installation of new HVAC and door closure systems, renovation of interiors and fitting of passenger information devices, in addition to corridor connections between carriages.
