Thanks for your offer, Pim! I've had answers saying the probability is "storeroom" which would be perfect as 4 of us will be travelling with our big overseas suitcases. However, one of the respondents at RENFE used consignas in the plural which could imply lockers. If you have any connections with RENFE, could you verify if the Cordoba train station has a storeroom or lockers large enough for big suitcases? Saluditos y muchisimas gracias, Chica369
