>>1080813>"Non federal lines", are they like preserved railways?They're all lines that are not owned by DB (both the federal railway and the current """privatised""" but still federally owned company).
Instead they are owned by the states, by cities or counties or by other non-DB private companies.
These are mostly rural branch lines and were not affected by the 1977 DB steam ban. While most of them weren't operating steam anymore but switched to cheap DMU operation early on (otherwise they wouldn't have survived to this day), some saw the touristic opportunity of heritage operation and allowed preservation societies without their own track to use theirs.
Pic related was on a line of the HzL railway that is owned by the state of Baden-Württemberg and two counties.
>>1080809 is from a preservation group called UEF that operates on the tracks of the AVG, a rail company owned by the city of Karlsruhe.
