Body of former narrow-gauge rail KBK close to Tetín
K.B.K., narrow-gauge rail Králův Dvůr-Beroun-Koněprusy ("King's Court-Beroun-Whytehorses") connected many limestone quarries on the western side of Český kras ("Bohemian Karst") between 1897 and 1962. Today, most of it's remains may be seen close to Tetín ("Teting") and Koněprusy, but the track is already replaced by pathways and thorny bushes.
