At Troyes it crosses the Seine again, and turns east. It enters the Aube valley near Jessains, and continues upstream along Bar-sur-Aube. It leaves the Aube and enters the upper Marne valley at Chaumont. It passes Langres and the railway junction Culmont-Chalindrey, where it crosses the line Nancy–Dijon. It reaches the river Saône at Jussey, and follows it downstream until Port-sur-Saône, where it turns southeast to reach Vesoul. It turns east, passing Lure, Belfort, Dannemarie and Altkirch.

History

The construction and exploitation of a railway from Paris to Mulhouse was conceded to the newly formed Chemins de fer de l'Est in 1853. The first section that was opened in 1848 led from Flamboin-Gouaix to Troyes, and was part of a railway from Montereau-Fault-Yonne to Troyes. The section from Paris to Noisy-le-Sec was opened in 1849, as a part of the Paris–Strasbourg railway. In 1856 a line from Noisy-le-Sec to Nogent-sur-Marne was built. The sections between Nogent-sur-Marne and Flamboin-Gouaix, between Troyes and Langres, and between Dannemarie and Mulhouse were opened in 1857. Finally in 1858 the section between Langres and Dannemarie was opened. Services
