I think it is fair to say that while Amtrak doesn't entirely "make rates up as they go", there's a lot of questionable black box nature to the numbers regarding overhead allocations and the like. Amtrak has a lot of room to perform alchemy on some of the figures, and this has been a sore point for some time.
Probably the best-documented example of this can be found in the history of the expenses of the Pacific Surfliners, which IIRC saw its operating costs triple in the space of about three years in the 1990s due to an overhead shift (this was, not coincidentally, right as the Desert Wind/Pioneer were getting cut and so on).
