Are these the branches that weren’t going to be included?
Only two of them are. I made this map as part of my suggestion for an extension to Riesa - Dresden (including the BR 146.0 and maybe the BR 145), consisting of three branches, among which the line over Dresden Friedrichstadt (the middle branch on this map), which wasn't originally announced. The left and right branches are the Meißen and Dresden Flughafen branch respectively, and those two are the branches that were announced at first but are no longer coming.
Separate names with a comma.
