The Lackawanna did this too. Unfortunately, I do not remember exactly why. It might surface after a while. You could ID the cars that had this done after they were de-converted by a line of empty rivet holes in the sides.

Re: [RealSTMFC] Increasing slope sheet angle on hoppers
Is there a listing of on line shippers for GN?
Or any conductors switch lists or yard lists or junction interchange lists for GN available?
Maybe these documents could assist in identifying the commodity.

In 1955, GN changed the slope sheet angle on some of their 73000-73199 hopper cars:
from about 30 degrees to 55 degrees, and renumbered them into the 73700-73764 series. The cubic capacity dropped from 1622 to 1253.
I've asked after this matter on the GN group. Nobody knows why.
So I'll bring the subject up here.
What load would GN have modified these cars for?
I'm interested in factual knowledge, and also informed speculation, since I have doubts anyone knows specifics on this matter.
My suspicion is that it was for "ore", or what most civilians would call "dirt".
I will also speculate that if the "ore" were no longer being transported, they'd be prized as hopper cars that would dump just about anything.
