Since couple of years, with the beginning of Spring we travel to Upper Silesia to participate in a special event. From 13^th to 14^th April we took part in the 10th International Fairs of Industrial Heritage and Underground Tourism which took place in Zabrze’s Sports Hall. This year we shared our stand with colleagues from the Association of Upper Silesia Narrow Gauge Railroads. This way, in one place the visitors could learn about the offer and history of our engine shed and the longest continuously operational narrow-gauge in Poland connecting Bytom with Miasteczko Śląskie.
