Based on the model of Alco DL-500, the series 321 of Renfe was at the time formed by 80 locomotives. Currently the locomotive 2148 is in charge of the company ALSA for the realization of tourist trains. The train in the photo had been rented by the British railfans of PTG who were making between Madrid and Teruel, the first part of a great railway trip through Spain. Over the bridge we were about forty railfans waiting for this train.
