And it's not only the poor and forgotten areas that aren't electrified.
- The link between Hamburg and the island of Sylt isn't (one of the most profitable ones)
- The ICE-link between Hamburg and Puttgarden (to Copenhagen) isn't (one of the most busiest around 110%++ capacity)
- Large parts of Swabia, one of the most industrious areas of Germany are completely un-electrified apart from the ICE-link between Munich and Stuttgart. Getting from Aalen to Lake Constance or Kempten via Ulm you will see a lot of "Mittelstand"-Companies but not a single electrified track.
These trains are being considered for use on similar regional stretches currently served by diesel-electric trains in the Netherlands as well.
