The ICE-TD (a 4 part tilting diesel set, used in later years for the Berlin-Hamburg-Puttgarden ferry-Kopenhagen line), which was taken out of service last year, finds new life as an inspector train.
Happy to see that they found a use for the ICE-TD. I've always found a diesel "high speed train" very cool because of its uniqueness. Even though the software, tilting system and fuel mileage aren't great.
