 However, in the Départements of Bas-Rhin, Haut-Rhin and Moselle, trains normally run on the right and so signals are placed on the right.This area was part of Germany from 1870 to 1918; trains run on the right in Germany and the railways were built during that period.When the area became French again in 1918, the railway network was almost complete, and trains ran on the right.
