 A further delay has arisen as a second cost-benefit analysis had to be carried out for the electrification to Grävenwiesbach, which was planned as a second stage.Therefore, the planning approval procedure for the electrification to Usingen will start in 2018.Accordingly, the Verkehrsverband Hochtaunus, as the owner of the line, had not yet announced the approval of the electrification works as of mid-2017.
