1) Germany, tank-to-wheel (TTW).
2) Since 2018 including RBH Logistics.
3) Previous years’ figure adjusted.
Modern rolling stock can convert a proportion of its kinetic energy into electrical energy during braking, allowing this to be fed back into the traction current grid no. 19. In the year under review, the recovery rate increased to 15% (previous year: 14%). The fleet vehicles that are able to “recycle” electricity is currently growing, thanks in part to the delivery of further ICE4 in the year under review.
