Reading this today and saw this quote.
It's an interesting theory that I like better than "crew safety".
During the 1960s when DW Brosnan was Southern's top dog, yeah, running long-hood forward had nothing to do with safety. The read
reason above is most plausible. From what I gather, Brosnan disliked the operating unions, along with just about everything and everyone else.
Note what happened after the SOU-NS merger: back to short hood forward.
