 The complex will be fully underground excepting for the station building, with two levels of platforms, accounting for a total of 18 railway tracks.The new station is part of a larger urban redevelopment project along the corridor formed by the railways accessing Barcelona from the north-east, which divides the districts of Sant Andreu and Sant Martí.This project includes the rebuilding of Sant Andreu Comtal railway station, to the north of Sagrera, and the construction of a linear artificial park over the railways running on the corridor, which will be put underground.
