One potential source of data that is often overlooked is the Historic American Engineering Record (HAER) which has a number of reports related to standing (at least at the time) roundhouses and repair facilities.

 Although these are not overtly archaeological and often are mostly architectural and engineering documentation, the wealth of data in these reports may be helpful for understanding an archaeological deposit. I have done some work with the railroad roundhouse and shop complex in Jamestown, California which might be of some help. If you have any questions I would be happy to assist you.
