I cannot speak to the Q's reasoning but know from conversations with folks
working for carbuilders that other RR's & private owners in the "70's chose
combo doors (1 sliding & 1 plug) as the latter seals better if you have a load
that needs to be kept sealed from outside dust, etc. Sliding doors, although
cheaper, become bent & 'out of square' by their nature & cannot be 'sealed' as
a plug can. Also harder to open/close. Thus if a large item, both doors could
be opened but if normal content, only the plug would be used which then sealed
better.
This subject makes me think getting someone who was with a major carbuilder
supplying the Q in the 50's/60's would be a good speaker for a BRHS meet if we
can't get someone who was in the Car Dept.

Subject: [CBQ] Double Dr Box Car Question
Been having a lot of conversations with Bill Glick lately about double door box
cars, specifically the 40 foot combination cars, classified XM-2's #41000
series (see Mike Spoor's book page 55).
WHY a plug door plus a regular box car door? Is there a divider that separates
the car info 2 compartments? Just don't know why 2 different doors are needed.
I can see the need for a double door such as the XA-8 #11000 series (same page)
so that larger items can be loaded, just seams strange to us, but I am sure
that someone has the answer.
