First, exclude the distribution area; there are very many trains there, closely packed together, not to mention the risk of survivors attacking and zombies sneaking into your house without you noticing.
The remaining areas include the container loading area, warehouse area, and dispatch stations, but none conform to the traditional sense of a shelter.
