This part is still misleading: "The ICE test train used was a Velaro Novo test car from Siemens Mobility" The test train used is a set from the late 20th century. So old that its regular brethren are already scheduled for retirement. This is the last generation of ICE that was still using separate locomotives (and with that, limited traction) instead of powered wheelsets distributed all over the full length of the train. The only thing Velaro Novo in this demonstration is that they inserted an unpowered prototype car into the trainset.

https://de.wikipedia.org/wiki/ICE_S https://de.wikipedia.org/wiki/ICE_S The theoretical assumed Vmax of this old train should be 440 km/h. The fasted actual speed was 406,9 km/h back in 1988. The test itself was focused on the Velaro Novo: https://en.wikipedia.org/wiki/Siemens_Velaro#/media/File:Wagen_Velaro_Novo.jpg https://en.wikipedia.org/wiki/Siemens_Velaro#/media/File:Wag... https://en.wikipedia.org/wiki/Siemens_Velaro https://en.wikipedia.org/wiki/Siemens_Velaro Design targets from German Wiki: * 15 percent less mass * Up to 30 percent less energy required (I guess that is on focus of this test) * Target speed 250 between 360 km/h * 30% less maintenance costs * 10% more seats I like the concept of the Valero (ICE3) the design with the engines below the floor of passenger cabins is elegant. The press text is unfocused and seems "Marketing". The DB probably cares more about the fact, that the ten year old track is maintained in good condition. The biggest problem of DB is bad maintenance of tracks and trains. Caused due to the attempt to make it a profitable stock company and weird split-up of tasks between sub-corps and the state as fallback. It should have been remained a one public state railroad not focused on earnings. Sins of deregulation and privatization of the 90ies. PS: Interestingly Deutsche Lufthansa is known for the well in-house maintenance branch. That's why they're happy with the B747-8. Not so big as the A380-800. The maintenance of four engines doesn't require them much effort. Here everything is in one major corporation and the need for good maintenance quality is intrinsic.
