The Karlovy Vary Lower Railway Station – Johanngeorgenstadt forms an important regional rail link between the regional town and settlement north of it. Due to the management of the Krušné Hory mountains, it also provides daily commutes as well as recreational tourism. The connection to the German railway network connects Karlovar with the adjacent area of Saxony (Zwickau and its surroundings). The purpose of the construction is to increase the cruising speed on the line by removing permanent line speed limitations.
