Thanks to all who replied to my TAG question. I was always curious as to the heritage of TAG, DT&I, OP&E and NP round roof boxes. Even the Ashley, Drew & Northern ran some 40-foot double door round roof boxes. These appear to be of PRR design with the rows of widely spaced rivets running parallel to panel seams.
What happened to the N&W 40- and 50-foot round roof boxes? Scrapped?
