the station developed into a small railway junction in the following decades. Deutzen () Deutzen station was opened on 15 November 1919. At this time, the village of Deutzen, now known as Alt-Deutzen ("old Deutzen"), was east of the modern Deutzen in the area now covered by Borna reservoir. At this time, the town experienced enormous population growth due to the opening of a brown coal mine. East of the station, the Deutzen opencast mine was put in operation between 1910 and 1963. After 1965 the town of (new) Deutzen was built on the already worked area, since the centre of the old town had been subsumed by the Borna-West open-cast mine. The area west of the station and the railway is currently being worked by the United Schleenhain coal mine. Regis-Breitingen () Breitingen halt was renamed Breitingen–Regis in 1902 and reclassified as a station in 1905. With the merger of Regis and Breitingen as Regis-Breitingen in 1920, the station also changed its name to Regis-Breitingen. The station is the last stop in Saxony in the fare zone of the Mitteldeutscher Verkehrsverbund (middle German transport association). It has formed part of the S-Bahn Mitteldeutschland since 15 December 2013. Treben–Lehma () Treben–Lehma halt was opened on 2 December 1889 as Trebanz–Treben. Between 1905 and 1970, it was classified as a station, but since then it has been a halt. It was renamed Lehma in 1952, but it has been called Treben–Lehma since 1953. Travelling towards Hof, Treben-Lehma is the first station in the state of Thuringia (it was in Saxe-Altenburg until 1920). It has been served by the S-Bahn Mitteldeutschland since 15 December 2013. The station is located in the municipality of Treben between the districts of Treben in the north-east and Trebanz (in which it is located) and Lehma in the south-west. In addition to the entrance building, the freight sheds and the workshops are also preserved. Altenburg () Initially, Altenburg was a terminal station, as the Duchy required the station to be as close to the town as possible. Since a direct extension to the south was not possible with the technology then available, trains, after reversing, originally continued of a line that bypassed the town to the east. Since the dead-end station on today's Fabrikstraße became more and more of a problem for rail operations, planning for a change of route commenced in 1871. Instead of building a
