Overview

DB Regio AG, Regio Südwest was a regional business division of DB Regio AG, the Deutsche Bahn regional passenger-transport company. It was formed on 1 January 2015 by combining the former Südwest and RheinNeckar business divisions. The two areas had already shared a managing director before the consolidation. On 1 January 2017, Regio Südwest was combined with the Hessen region to form Region Mitte. Some activities and vehicles in Baden-Württemberg were taken over in part by the newly established DB Regio Baden-Württemberg. The division operated the Rhine-Neckar S-Bahn and most regional lines in the Rhine-Neckar region and Saarland. Its services also included regional express and local rail networks in the wider southwest. The Süwex-branded regional express network entered service in 2015 and connected Saarland with Kaiserslautern, Koblenz, Frankfurt, Mannheim and Karlsruhe. The division also operated special trains for football matches involving TSG 1899 Hoffenheim and 1. FC Kaiserslautern. Its fleet varied by route and electrification. The supplied German Wikipedia entry describes electric multiple units from the 425 series in parts of Baden-Württemberg, several types of diesel multiple units on non-electrified routes, and Stadler FLIRT 3 trains for the Süwex network. It also records operations on the Lahn-Eifel-Bahn and along the Moselle, and cooperation with regional transport operators on parts of the AVG Stadtbahn. The evidence identifies the division as a former organizational unit rather than a currently operating standalone company. The S-Bahn Rhein-Neckar website supplied here provides current passenger information for the service, but does not establish that the former division remains in existence.

History

DB Regio AG, Regio Südwest was established on 1 January 2015 as a consolidation of the former Südwest and RheinNeckar business divisions of DB Regio AG. The supplied German-language article notes that the two regions had already shared a managing director before they were formally combined. The resulting division managed regional passenger rail operations in southwest Germany, with responsibilities including the Rhine-Neckar S-Bahn and most regional lines in the Rhine-Neckar region and Saarland. The division's operations covered a mix of urban, regional and regional express services. The Süwex regional express network began operating in 2015. Its routes linked Saarland with Kaiserslautern, Koblenz, Frankfurt, Mannheim and Karlsruhe. In Trier, the RE 1 trains were coupled and divided with RE 11 services operated by Luxembourg's CFL, according to the supplied article. The division also ran special trains for matches involving TSG 1899 Hoffenheim and 1. FC Kaiserslautern, and cooperated with the Albtal-Verkehrs-Gesellschaft, Verkehrsbetriebe Karlsruhe and Stadtwerke Heilbronn on parts of the AVG Stadtbahn. The fleet reflected the range of services and railway infrastructure in the region. The article describes use of electric multiple units from the 425 series in the Baden-Württemberg catchment area, and diesel multiple-unit types including Bombardier Talent and Siemens Desiro Classic on non-electrified routes in Rhineland-Palatinate. It also records the introduction of Alstom Coradia LINT 41 and LINT 54 units on parts of the Dieselnetz Südwest from around November 2015, replacing older class 628 units on those services. For the Süwex network, new Stadler FLIRT 3 units were used. The article further notes rolling-stock modernization for the first S-Bahn Rhein-Neckar lot from late 2015. The organizational unit did not remain separate for long. On 1 January 2017, Regio Südwest was combined with the Hessen region to form Region Mitte. Some activities and vehicles in Baden-Württemberg were partly transferred to the newly established DB Regio Baden-Württemberg. Accordingly, Regio Südwest is described here as a former DB Regio business division, not as a current standalone company. The passenger-facing S-Bahn Rhein-Neckar website continues to provide information about regional journeys and tickets, but the supplied evidence does not state that the former division itself continues to operate.
