For anyone who was dying of curiosity to know, in no particular order, and with uncertainty that this list is complete, here are the 9464 Standard O boxcars that were produced with a die cast frame. Some of the blurbs on the Lionel website indicate that some of the PS1 boxcars were produced with die cast frames. As an aside, Lionel also has a series of 6565 (6464 sized) boxcars with die cast frames.
NY Central 6-17247; released for separate sale, and, as part of the 6-17246 NY Central Freight set, which included 2 additional NY Central Std. O Boxcars in the Pacemaker scheme, both with die cast frames, 6-17248 & 6-17249, and a Pacemaker Caboose, with a plastic frame.
