I thought about this after posting my inquiry and figured that was the probable situation. One problem we run into contantly with historic structures is code compliance with current building codes. Most of the time, in our work, we can deal with the local building officials and the Uniform Building Code does have a sub-section for the Conservation of Historic Structures that allows variances to many, but not all current code requirements. Places of assembly do come under much stricter requirements, and once in a while we lose the battle and historic material, doors, stairs, etc., bite the dust in the name of health and saftety issues. Handicap access to buildings does more to destroy their character than anything else, but that is the desire of the community (and the courts) as expressed in building codes.
As far as the Silver Plume depot, perhaps someone should ascertain the complete facts before all the nastiness? Then let loose if it is justifiable.
