So at the time of construction I imagine the techniques used to make a building look like some kind of classical architecture while actually being a facade on top of a steel skeleton must have been fairly new and experimental.
Was the maintenance story perhaps just not well thought through at design time?
It seems almost impossible to simultaneously design a building with recently developed construction techniques, to achieve such an impressive looking result, and to also nail any reasonable maintenance strategy as part of the design.
Lots of other stations built in the same style in the same period remain well-preserved and functional- Grand Central in the same city, opened 3 years later, being a prime example.
