From 1904, Frei-Weinheim had a railway connection for goods and passenger traffic for exactly 50 years. The former train station building in Heimat style is still preserved.
The single-track Selztalbahn connected the Rheinhessen hinterland from Jugenheim-Partenheim to the port in Frei-Weinheim. In Nieder-Ingelheim, there was a connection to the left bank Ludwigsbahn, which had been running between Mainz and Bingen since 1859. Since the Selztalbahn was primarily used for the transport of sugar beets, it was nicknamed “Zuckerlottchen.” Frei-Weinheim housed the railway depot. The railway line also benefited the new industrial settlements, such as the white lead, black color, fertilizer, and chemical factories. For them, the handling of coal, which was landed at the port, was particularly important. A coal column was on standby for this purpose. The increased individual traffic for goods and passengers made the route unprofitable, leading to its closure in 1954. The tracks were removed in 1996. The former route is reflected in the horseshoe-shaped layout of Frei-Weinheim west of Rheinstraße.
