The section of the 117 railway line between Bielsko and Kalwaria Zebrzydowska was opened on 1 June, 1888. It was one of the lines of Emperor Ferdinand’s Imperial Privileged Northern Railway. Initial plans to build a line from Kęty westwards were different. The railway was to bypass Kozy and lead through Wilamowice to Dziedzice.  According to oral accounts, personal efforts of the owners of the manor estate, Major Stanisław Klucki and Herman Czecz de Lindenwald, led to the change of plan and, despite the difficult terrain, the railway line was eventually led through Kozy. Among the workers building the stone bridges and culverts were Italian POWs from the Austro-Prussian War of 1866. The station in Kozy is typical of the small station buildings along Austro-Hungarian railway lines.  In the 1920s, the station gained an extension which housed the waiting room. In 1990, railway line No. 117 was electrified. The first stationmaster in Kozy was Karol Schnapka from Opava, the second in 1894 - Franciszek Knorre, the third in 1896. Franciszek Merka, then in 1907. Stanisław Krzemień and in 1914 Andrzej Jakobsche.  On 5 May 1917, a train carrying the Emperor Karl Habsburg, Emperor of Austria and his wife Zyta de Burbon-Parmena arrived at the station in Kozy. On the platform, the couple were greeted by Baron Marian Czecz de Lindenwald in a Polish nobleman’s outfit.
