“Electrification, yes, but an optimal!”
I wonder which voltage system will be applied for the “islands”, if actually isolated from the remaining railway grid. Using 50 Hz should be much easier to supply from existing public grid, rather than install inverters at each of the “islands”. In case of 50 Hz/25 kV, it would be international railway standard, whereas 50 Hz/15 kV probably would need less changes as compared to existing German systems.
This figure probably refers to 40% of train-km, but not ofpassenger-km. Also, long-distance trains possibly are not taken into account for the figure.
