The Espai de la via mètrica is the center for the preservation of historic railway vehicles on the Llobregat-Anoia line and is located next to the Martorell Central station.

More than twenty locomotives, cars and wagons that provided service on the Llobregat-Anoia line up to the present day, both for passengers and goods, are exhibited in the space, and are a testament to the evolution of rail transport in Catalonia.
