Facinating set of pictures, thanks for posting. Interesting place, intriguing to see how the concept of the fully electric loco has developed. Is the TEE set one that can still be run ? Seems Germany is coming to terms with its past, given some of the insignia displayed on one or two locos. A big no no when Mercedes and VAG (Auto Union) demonstrate and display their racers and rekordwagen from the 1933 - 45 era.
As an aside I came across by pure chance a place in the Eifel region, returning home after a visit to the Nürbergring in my little jalopy in 2007,

Oh, my little ( mid life crisis) jalopy posing at the Nurburgring
