When is The Underground Not an Underground ?

This isn't a bridge  it isn't a flyover , it's the UBahn or underground at U Bülowstraße.  Yes I did say underground .Such stretches rise from the ground and allow the gloriously bright  BVG yellow ubahn to surface , rise and pass over head before, gradually. returning under the ground .As can be seen in the extra, the station is also up aloft. This station was built in 1902. There are several through out the city .Not to be confused with the SBahn though .
Fooled any of you ? Maybe , Maybe not .Thanks to davidc for hosting the challenge .
