410 101-0 at the rear end of the ICE-S, seen at Köln Ehrenfeld short after the arrival from Düren on 16 June 2003. This train was originally built for testing the technical concepts of the ICE 3, and operated with three intermediate cars forming a "half ICE 3" (transformer car and two cars with traction motors). Now it is operated with less intermediate cars for different testing purposes. In this case it seemed to be a test run of the new highspeed line Cologne-Düren (ABS 4), where ICE and Thalys trains shall run with 250 km/h in the future.
