Southern Hesse (RMV) regional services
The Rhine-Main Transport Association has given unique numbers to its regional railway services in regular operation.

The lines are mainly run to and from Frankfurt as the metropolis of the Rhine-Main region, but there are also a number of connecting lines between the major towns of the whole area.
