We are a cultural association and we are conscientious that our experience and knowledgement should be spread over. Since our very beginning we have participate in several divulgation activities. Our first public actuation was at the “Trens i Estacions” exhibition, at the beginning of the year 1981, at the old building of “Mercat del Born” in Barcelona. There took place the first public demonstration of a little train moved by steam power, constructed at scale and man-riding operated. From that moment onwards we participated at the first editions of the “Salon de la Infancia” in Barcelona, we performed exhibitions of our scale material at the “Ramblas” promenade in Barcelona with occasion of a sort of journeys organized by the already disappeared newspaper “ El Correo Catalan”, and as well we did at the “Plaça dels Paísos Catalans”.
