One thing that I did find about BERLIN is that when you use the keyword KRYPTOS with it in a Vigenere table and use BERLIN as the passphrase, and NYPVTT as the message text, it solves to ELYOIE.
Now before doing the columnar transposition on the lower left panel, the variables are:
TNHAEOETFOLSEDTIWENHAEIOYTEYQ
EIOYTE
That is really close to what is needed to solve to BERLIN and exists in the existing cipher string.
