Actually, the Freight Car Department is my area and I can give you a firm answer on this one.
Yes, we plan to do the B&O boxcar as our next restoration project. A lot of the research and planning is done, new steel for repairs has been ordered and delivered, and the physical work started this past week. Most of the car has been emptied and some of the interior wood car lining has been removed to allow welding of the sides.
We are trying to do this with very limited funds, using almost 100% volunteer labor. But there are still expenses for paint and supplies, (donations to fund R374065), and of course anyone that would like to come out and help, you are welcome.
