I understand that it doesn't make sense for NS to keep the roundhouse, but my main point was the recent change in tax laws makes it nearly impossible for an independent group to come in and save the structure without a huge financial burden. Asheville has a track record of saving historic structures from the wrecking ball, and the tax incentives are a big reason why. While the recent tax laws may not play a huge role in the decision by NS to demolish the roundhouse, it certainly makes it harder to justify saving historic structures like the roundhouse.
Sorry if I came across a little politically strong there, my main point was to point out the loss of the structure. Here is a link relating to the roundhouse and the tax credits.
