Today's hyper-ugly Penn Station has 11+1 platforms with 21 parallel tracks. Köln Hbf only has 6 platforms (tough maybe wider ones) and 11 tracks.
Demolishing the old Penn Station is said to have been a first-order architectural crime - judging from the photos in the link, that appears to be true. *Lunatic*, n. One whose delusions are out of fashion.
