Belfort - Mulhouse-Ville line 442.6 Belfort 454.2 Petite-Croix 456.7 Montreux-Vieux 464.9 Dannemarie 474.2 Altkirch 481.1 Illfurth 490.9 Mulhouse-Ville 108.4 ***** In Belfort, located in the Porte Bourguignonne, it connects the railway lines to Besançon Dole, Vesoul Paris and Méroux Delle. This railway line heads east on a gentle ridge and side valleys near Montreux-Château in the Bourbeuse valley parallel to the Rhone-Rhine Canal. The Rhine-Rhone high-speed rail line also passes here, the canal is crossed further west at its highest point in Valdieu-Lutran in the south and, unlike the waterway, which was built after the watershed to the Rhine in the Largue valley, the railway route runs south through the foothills of the Jura directly to the Ill valley, which it reaches at Carspach and follows in a straight line, from Illfurth still with the canal, to Mulhouse in the Rhine valley. In Mulhouse there is a connection to the Strasbourg-Basel, Thann and Müllheim railway line. At the time of the Compagnie des chemins de fer de l'Est, it was numbered "line 40". In the old nomenclature of the Eastern region of the SNCF, it was numbered "line 4" and referred to as the "Paris – Basel Line". After 1871, following the annexation of Alsace-Lorraine to the German Empire, Montreux-Vieux station was expanded and became a border station. A new station was built on the French side at Petit-Croix. The section from Montreux-Vieux to Mulhouse was managed by the Imperial General Directorate of Alsace-Lorraine Railways and trains ran on the right according to German standards. When Alsace and Moselle became French again after the First World War, a flyover was built at Illfurth to allow trains to change direction. It was destroyed around 1970, with the change of direction now taking place at Mulhouse station. Launched on 2 June 1957 on the line between Paris-Est and Zurich (via Troyes, Mulhouse and Basel), the TEE L'Arbalète was one of the first Trans-Europ-Express lines of the SNCF. The equipment used was SNCF RGP1 ​​(X 2700 + X 2770), then a Dutch-Swiss diesel train (CFF/NS) in 1964, and finally the CC 72000 locomotive hauling Mistral cars. After the connection to Zurich was stopped, the TEEs were replaced by Corail trains (finally called Intercités) Paris – Troyes – Belfort – Mulhouse (Basel until 2007), hauled by CC 72000 locomotives. During 2017, Coradia Liner trains (B 85000) ran with the last CC 72100s on the line, then the latter were completely withdrawn from service in August of the same year. Since January 1, 2018, these Intercités have been taken over by the Grand Est region; they became TERs on September 1 of the same year. The line was electrified at 25 kV – 50 Hz from Belfort to Mulhouse-Ville on 10 September 1970. Since the first section of this high-speed line was put into service, TGVs have used part of the Paris-Est to Mulhouse line between Petit-Croix and Mulhouse. As a result, the operation of the TER Alsace from Belfort to Mulhouse was reorganised to accommodate all the trains. This involved the closure of the three stations of Valdieu, Ballersdorf and Brunstatt, in order to reduce TER journey times. The closure of Flaxlanden station was also planned, but it was saved following discussions and thanks to the mobilisation of local residents through a petition. The SNCF and the Alsace region hope to be able to reopen these stations when the second phase of the LGV Rhin-Rhône between Petit-Croix and Lutterbach is put into service. ******* The Paris–Mulhouse railway line refers to Paris with Mülhausen and Troyes, Chaumont, Vesoul, Lure and Belfort. Ihr gebräuchlicher Name in der SNCF-Region Est ist Ligne 4. Sie wurde et appenweise zwischen 1856 und 1858 eröffnet. Früher wurde die se Strecke auch vom Arlberg-Orient-Express und dem Trans-Europ-Express „L'Arbalète“ auf der Strecke Paris–Schweiz benutzt. Seit der Inbetriebnahme der LGV Est Européenne hat der Personenfernverkehr stark nachgelassen. 1871 to 1914 verlief of the German-French Grenze zwischen den Bahnhöfen Petit-Croix (französischer Grenzbahnhof) and Montreux-Vieux (Deutscher Grenzbahnhof). Der in Deutschland gelegene Teil der Strecke gehörte zu den Reichseisenbahnen in Elsaß-Lothringen. Die Schnittstelle zwischen dem aus deutscher Tradition stammenden Rechtsbetrieb und dem in Frankreich herrschenden Linksbetrieb überwand kreuzungsfrei ein Überwerfungsbauwerk zwischen den Haltepunkten Illfurt und Zillisheim. ********** Rolling stock: Régiolis self-propelled train – B 84500 – Alstom DBC explanation • SNCF training – CABRIDE 4K MAP hot box: http://cabride.infos.st/
