Probably brackets for something on the inside of the car, maybe side rails for load divider bulkheads? Just a guess.

I was thinking the same possibility, but the cars in that series are classified XM with no callouts for special equipment.

What are is the function of the 2 large rivets between each steel panel about a foot from the edge of the roof?

...and the rivet pairs are repeated in the middle and near the bottom of each panel.
???? another rib? load handling?

I don't know what they're for, but the rivet pairs are not vertically in line
with each other on the side panels.

Also on the ends of these 743-B cars, with 4/4 ends, there are a pair of rivets
in ribs 1-3-4-5-6-8 from top to bottom. That does seem to jive with the theory
that the rivets are for an interior lining.

Dave - I have a question about the type of roof indicated on your mechanical drawing for the NYC Lot 743-B boxcars.  In post #126331, you indicate that the cars had a "STANRAY roof".  Since the 2,000 boxcars in Lot 743-B were built in 1945, does this "STANRAY" mean the diagonal panel roof?  (I thought it was first applied to freight cars in late 1948!?)  Does the Stanray mean a flat panel roof (sans diagonals) by the same manufacturer?  Or is your mechanical drawing for the 500 cars modified in 1965-66 and placed in Lot 969-B?

Thank you for your response!

Ed Hawkins' spreadsheet lists Lot 743-B having rectangular panel roofs, not a diagonal panel roof.http://www.steamerafreightcars.com/prototype/frtcars/postwaraarpdf.html

The modeling recommendations at http://www.canadasouthern.com/caso/NYC-MODELS-FREIGHT2.htm are misleading for both 743-B and 969-B - AFAIK, no postwar AAR boxcars were built with carbuilder's flat panel roofs.  The the photo of the lot 969-B cars is inconclusive regarding rectangular vs. diagonal panels, but you'd think if the cars were given new roofs (which I find highly unlikely), they would have received overhanging-eave roofs given the date.

Ben -  Thank you!  I am wondering what mechanical drawing Dave has that gives roof type, truck type and running board type information.  None of my pre-1948 NYC diagrams have that; nor does Ed Hawkins' fantastic compilation of the 1944 AAR 40' boxcar data (for Lot 743-B, that is) - except for the roof type.

I am trying to build up a small roster of NYC 40' boxcars circa April, 1948.  I have one USRA double sheathed car, six clones of the all-steel USRA boxcars, one 1937 alternate design boxcar, and would like one 1944 AAR car with 4+4 improved Drednaught ends - that is my reason for asking.  This should balance out my 14 PRR boxcar fleet!  Down here in south Texas, we saw more PRR cars on MP than NYC cars, and about equal numbers of NYC and PRR cars on the M-K-T.

Thanks again!

The 969-B cars had rectangular panel roofs -- At least they do in the
two roof shots I have.

Thanks, Tim!

In your roof photos, can you see whether they have US Gypsum running boards?  Also, can you see what make of handbrake they had?

A.T. Kott

In the photo that Ben linked, the handbrake is clearly Ajax. But
in one of my photos, it appears to be a Ureco.

The running boards and brake platforms are Apex.
