The "Tren del Cemento" is a historic, narrow-gauge railway, founded by the General Company of Asfalts and Portland Asland to exploit the line that connected Guardiola de Berguedà and the first portland cement factory created in Spain. It was inaugurated between 1911 and 1924. This old train, with its diesel locomotive, covers a 3.5 km journey that lasts approximately 20 minutes. It has four cars that have a capacity for 25 passengers each. The last stop of the train is the Cement Museum, which used to be the Asland cement factory located in the area of Clot del Moro, in the municipality of Castellar de n'Hug.
