more new ones. From June to November 2008, the district of Rottweil examined expanding Ringzug operations to the Rottweil–Horb section. In return, however, the Regional-Express stops in Sulz am Neckar and Oberndorf am Neckar would have been eliminated. However, this model ultimately failed due to resistance from the affected towns of Oberndorf and Sulz. Oberndorf station was modernised in 2014 and 2015 at a cost of €2.9m. Between 6 June and 22 November 2016, 28 kilometres of track and 44 sets of points were renewed between Plochingen and Tübingen for €27m. The section between Reutlingen and Tübingen was completely closed due to construction work between 12 November and 3 December 2021. Passenger operations Only the section between Horb and Tuttlingen is used by long-distance rail passenger services apart from a few IC train pairs on the Stuttgart–Tübingen section. There are hourly intercity trains on Intercity line 87, which can also be used by passengers with local rail passenger transport tickets. The following lines operate in local transport: With the timetable change in June 2020, Abellio Rail Baden-Württemberg took over the electrically-operated services between Plochingen and Tübingen. The procured electric railcars were not available at the beginning, instead rented railcars were used. Especially in the first few weeks after the start of operations, a lack of rolling stock and technical problems led to numerous train cancellations. In regional transport, between Plochingen and Bempflingen the tariff of the Verkehrs- und Tarifverbund Stuttgart (VVS), applies, from Bempflingen to Eyach that of the Verkehrsverbund Neckar-Alb-Donau (naldo), from Eyach to Horb that of the Verkehrs-Gemeinschaft Landkreis Freudenstadt (VGF), from Horb to Immendingen that of the Zweckverband Verkehrsverbund Schwarzwald-Baar-Heuberg (VVR). Freight operations Starting in Plochingen, regular freight traffic now operates from and to Wendlingen am Neckar (from there on to Oberlenningen), to and from Nürtingen (from there on to Neuffen) and to and from Metzingen (from there on via the Ermstalbahn to Dettingen an der Erms). The town of Reutlingen has secured the site of the former goods yard in order to have a site ready for the construction of a container yard in the long term. The site of the former Tübingen freight yard was largely cleared in 2015 and the tracks were removed, and the freed-up areas were subsequently developed. On one to two working days a week, the route is served in the mornings by a Hohenzollerische Landesbahn train running from the Tübingen
